Abstract:
Midges (Anarete pritchardi) coordinate their flight motions to form a cohesive group during swarming. In this paper, individual midge motion dynamics, sensing abilities, and flight rules are represented with a midge swarm model. The sensing accuracy and flight rule are adjusted so that the model produces trajectory behavior, and velocity, speed, and acceleration distributions, that are remarkably similar to those found in midge swarm experiments. Mathematical analysis of the validated swarm model shows that the distances between the midges' positions and the swarm position centroid, and the midges' velocities and the swarm velocity centroid, are ultimately bounded (i.e., eventually satisfy a bound expressed in terms of individual midge parameters). Likewise, the swarm position and velocity centroids are shown to be ultimately bounded. These analytical results provide insights into why the identified individual midge sensing characteristics and flight rule lead to cohesive swarm behavior.

AbstractThe wheat midge, Sitodiplosis mosellana (Géhin), is an infrequent but devastating pest that has been present in western North America for at least 100 years. This note provides the first published report of the presence of the wheat midge and its parasitoid, Macroglenes penetrans (Kirby), in Montana. Annual surveys were conducted in Daniels, Roosevelt, Sheridan, and Valley counties of northeastern Montana for 5 years (2000–2004) using a systematic soil sampling method to collect overwintering wheat midge larvae. In addition, in 2004, infested wheat heads were collected from 10 fields in Sheridan County, and wheat midges and parasitoids were reared. The wheat midge occurred in all four counties, though at relatively low levels. Densities fluctuated across years and locations, with the highest densities (>200 midge larvae/m2) occurring in Sheridan and Roosevelt counties. Macroglenes penetrans was found at all 10 sample sites and constituted up to 52% of the emerged adults (midges + parasitoids).

Abstract:
AbstractIn 2002, two types of light traps were compared against sticky yellow cards for efficiency and selectivity in capturing adult swede midge Contarinia nasturtii (Kieffer) (Diptera: Cecidomyiidae). Incandescent light traps were more efficient at capturing swede midge than were sticky traps. Incandescent light traps were more selective than blacklight traps and required less time for processing of samples and identification of captured midges. Emergence (2003 and 2004) and pheromone (2004) traps were used to assess swede midge population dynamics. Captures from emergence traps indicate up to five overlapping emergence events for swede midge each year. Emergence traps captured swede midge earlier in the season than pheromone traps, but pheromone-trap captures continued later in the season than those in emergence traps. Pheromone traps are small and portable, easy to maintain, and capture significantly more swede midge than emergence traps.

Abstract:
AbstractA three-year field study in northeastern Saskatchewan, Canada, determined the effects of seeding date and seed treatment on feeding injury by Contarinia Róndani (Diptera: Cecidomyiidae) midges to canola, Brassica napus Linnaeus (Brassicaceae), and subsequent seed yield. Emergence cage monitoring indicated the presence of two generations of midges at the four locations observed. Intensity of midge injury to canola was low, but damaged plants were common. Field location and seeding date influenced probability of midge injury and canola growth stage. The wettest of the four locations had the greatest number of midges but low levels of probability of damage in two of three years. Early-seeded plots had higher injury probability than late-seeded plots, with the highest probability of injury occurring one to two weeks after flowering commenced. Seed treatment marginally affected midge injury ratings, suggesting that insecticide efficacy dissipated before the midges attacked. Seed yield was higher in early-seeded than in late-seeded plots in two of three years, despite the greater level of damage seen in early-seeded plots. Overall, the research showed that the agronomic benefits of early seeding outweighed the effects of the midge damage observed; therefore, producers in the Canadian prairie provinces should seed canola when conditions are most agronomically suitable.

Abstract:
AbstractSwede midge (Contarinia nasturtii (Kieffer); Diptera: Cecidomyiidae) is a serious invasive pest of Brassica Linnaeus (Brassicaceae) oilseed and vegetable crops in Canada and the United States of America. Pheromone mating disruption is a promising new tactic for managing this difficult pest, but research is needed to determine how pheromone delivery can be optimised. With an understanding of swede midge diel mating patterns, pest managers could limit pheromone release to periods when midges are sexually active. We conducted a series of 24-hour trials to test whether swede midge exhibit diel periodicity of emergence, female calling, and male capture in pheromone traps. We found that females began releasing pheromones almost immediately following emergence within the first five hours after dawn. In the field, we found that males were most active from dawn until late morning, indicating that midges mate primarily during the first five hours of photophase. Low levels of reproductive activity during midday and nighttime hours present opportunities to turn off dispensers and reduce the cost of pheromone inputs in a swede midge mating disruption system.

Abstract:
AbstractThe soybean pod gall midge is an important pest of soybean in Japan and is known to occur also in Indonesia and China. This gall midge is described from Japan as Asphondylia yushimaisp. n. and is clearly distinguished from its congeners by the arrangement of the lower frontal horns of the pupa and the sequence of the mtDNA COI region. It is concluded that Prunus zippeliana Miquel is a winter host of the soybean pod gall midge since haplotypes of the soybean pod gall midge coincide with those of the Prunus fruit gall midge that produces fruit galls on P. zippeliana. In addition, phenological and distributional information on the two gall midges and on their host plants supports the identification of the winter host. In Japan, the soybean pod gall midge overwinters as a first instar in the fruit galls on P. zippeliana and emerges as an adult from the galls in May. In summer and autumn, the soybean pod gall midge has two or more generations in the pods of soybean, Glycine max (L.) Merrill or wild fabaceous and caesalpiniaceous plants. Thus host alternation by A. yushimai is confirmed. This is the second finding of host alternation by a species of Asphondylia, the first instance being that of Asphondylia gennadii (Marchal) in Cyprus.

In the present study we described the structure of a trophic network composed by gall-midge species (Diptera: Cecidomyiidae) and their host plants in the Restinga of Barra de Maricá (Maricá, Rio de Janeiro, Brazil). Species data were retrieved from literature and different topological descriptors (links per species, connectance, and modularity of interactions) were used. All gall-midge species were monophages, with connectance of 2.8% of the 2,016 possible interactions. The network of host plants and gall midges had low number of links per species and high modularity, which indicates high specificity and specialization of plant-galling interactions in the area. This is the first characterization of a trophic network with good taxonomic resolution for the Neotropical gall midges.

Abstract:
Abstract Wheat midge, Sitodiplosis mosellana Géhin, is an invasive pest of wheat, Triticum aestivum L. (Poaceae) throughout Canada and the United States. The applicability of available monitoring tools, including sex-pheromone baited traps, yellow sticky cards, and soil core sample surveys, in the northern-most agroecosystem of its invasive range has not been assessed. In this study, the attraction of male wheat midge to two Delta traps (green and orange) baited with one of three pheromone lures (a flex lure and two red septa lures from different sources) were compared. The efficacy of three yellow sticky cards (7 × 12 cm, 14 × 18 cm, and 14 × 18 cm rolled into a cylinder) for capture of male and female midge was assessed. Larvae were extracted from wheat heads sampled at the same sites to determine relationships with earlier adult trap capture. More male adult midges were captured in pheromone-baited traps with a greater surface area and in traps baited with the Scotts flex lure than the Great Lakes IPM septa lure, which had higher and more variable pheromone release rates. The smaller yellow sticky cards captured more male and female midges than the larger yellow sticky cards, regardless of shape. The number of female midges captured on yellow sticky cards predicted the number of larvae in wheat heads. The number of male midges captured in pheromone-baited traps did not predict larval density. Relationships were found between the number of overwintering cocoons recovered in soil core samples and emerging midges the following spring.

Abstract:
Forcipomyia taiwana, a bloodsucking midge that is one of the most irritating biting pests in Taiwan, has raised widespread public concern. However, we have little information about the extent to which landscape factors affect their potential habitats. As a result, landscape professionals do not have enough information to implement preventive strategies to control midges. The purpose of this study is to investigate the relationship between landscaping and algae growth for larval breeding sites of Forcipomyia taiwana. The intent is to determine the environmental strategies that make the planned landscape unsuitable for midges to breed. GIS based on data collected from 16 constructed landscape sites (317,187 m2 in total) was utilized to spatially examine the relationship between the occurrence of the algae for midge breeding sites and the ground surface types and planting characteristics in each landscape. The results revealed that the potential midge habitats can be controlled through careful selection of the ground surface, the improvement of the site drainage, and choosing plants with the appropriate characteristics. Apart from choosing the appropriate type of paving surface, the integrity of the paving installation and the coverage of the ecological surface also influence prevention efficacy.

Abstract:
[Abstract]: The development and commercial release of midge resistant grain sorghum hybrids in Australia has been one of the real success stories of the sorghum industry. Almost all the current commercial sorghum hybrids grown contain a significant baseline of midge resistance that has greatly reduced that pest status of this insect. However while breeding efforts have been successful, it seems only one mechanism of resistance remains present in commercial hybrids. This mechanism of resistance known as ‘ovipositional-antixenosis’ is polygenic in nature and has contributed to the gradual reduction in the genetic base of commercial sorghum hybrids, potentially limiting the advancement of other agronomic traits.In order to expand both the level of resistance and the genetic diversity within Australian commercial sorghum hybrids, research was undertaken to capture new sources of midge resistance. Initially the goal of this work was to isolate and characterise the most promising new antibiosis sources of midge resistance previously documented within international breeding lines. However as the work progressed the discovery of a previously undescribed tolerance source of midge resistance led to more detailed studies of midge larval biology within a narrow range of sorghum germplasm lines to better characterise the resistance mechanism.To complete this work a new water-injection technique was developed to allow more precise studies of midge larval biology where previous traditional screening methods were deemed inadequate. Using this method several antibiotic lines were shown to contain diverse modes of action, while the tolerance mechanism of resistance was confirmed and more accurately characterised. In all cases plant characters within the developing spikelet were associated with each resistance mechanism.Overall, one source of resistance, found in lines derived from the Indian land race line DJ6514, was identified as superior to the others tested. Germplasm derived from this source was found to confer inter-related antibiosis and tolerance mechanisms. Both mechanisms were indirectly shown to be caused by the unique antibiotic properties of the developing caryopsis. Larval mortality (antibiosis) increased in this line, in line with increased feeding against the developing caryopsis. A second tolerance mode of action was also linked to anti-feeding properties of the developing caryopsis. Larvae were recorded at higher than normal rates feeding away from the caryopsis resulting in the survival of both larvae and grain in a significant proportion of spikelets. This escape ‘tolerance’ mechanism of resistance was confirmed indirectly in several studies and could be artificially induced in other genotypes when larval feeding against the caryopsis was delayed. As such the resistance is better described as antixenosis to caryopsis feeding.When both resistance mechanisms are present, the resistance isolated from DJ6514 was found to cause a three to four fold increase in seed set in resistant lines. This source of resistance has been directly selected for incorporation into the Australian breeding program and has been shown to be inherited simply as a single gene that needs to be deployed on both sides of the breeding program to ensure stable expression. When breeding efforts are complete a new suite of highly resistant and genetically diverse midge resistant sorghum hybrids will emerge into the marketplace.

Abstract:
The hypothesis that midge sex pheromones could be chemically more diverse in structure than previously thought was tested in the context of four midge species of importance to UK horticulture: pear leaf midge, Dasineura pyri; pear midge, Contarinia pyrivora; blackcurrant midge, D. tetensi; and blackberry midge, D. plicatrix. The major component of the pheromone of D. pyri was identified as (2R, 13R, 8Z)-2, 13-diacetoxy-8-heptadecene. Four isomers were separated by HPLC and in field tests the first eluting isomer only was attractive to male midges. Analysis of volatile collections from female C. pyrivora showed two consistent responses from male midges and they were identified as 2,7-diacetoxyundecane and 7-acetoxyundecane-2-one. The field testing with isomers of 2,7-diacetoxyundecane separated by HPLC revealed that the first and the third eluting isomers were attractive. The racemic 7-acetoxyundecane-2-one was active as well as the first eluting isomer from HPLC. Two EAG active components were detected in D. tetensi female volatile collections. The major component was identified as (Z)-2,12-diacetoxy-8-heptadecene and after separation of stereoisomers by HPLC the third eluting isomer has shown to be attractive to male D. tetensi in the field. The structure for the minor component was proposed as a keto-acetate homologue of the corresponding major component. Preliminary work carried out on identification of the female sex pheromone of D. plicatrix indicated two responses from conspecific males. These were shown to be 15-carbon acetates with the acetate function at C-2, probably with two and one double bonds respectively.

Abstract:
Sorghum (Sorghum bicolor [L.] Moench) production in many areas of the world is reduced due to damage caused by sorghum midge (Stenodiplosis sorghicola). There are several methods of control to reduce losses due to sorghum midge, which include cultural practices, biological control, chemical control and resistant cultivars. The best long-term solution for sorghum midge control is the use of genetic resistance in cultivars and hybrids. Recently, sorghum midge resistant hybrids have been developed by several sorghum breeding programs, but there is limited information about agronomic performance relative to planting dates compared to susceptible standards. Thus, the objectives of this research project are: (1) to evaluate the value of sorghum midge resistant sorghum hybrids in the USA production system, (2) to confirm the presence of sorghum midge insect resistance in sorghum hybrids, and (3) to determine whether the resistance in eighteen sorghum hybrids is stable across two environments in Texas where sorghum midge is a damaging pest. Sorghum hybrids with different levels of resistance to sorghum midge were evaluated at College Station and Corpus Christi, Texas in 2003 and 2004, using two different planting dates and the presence or absence of an insecticide treatment. Agronomic data, sorghum midge incidence ratings and number of adult midges, were determined for all entries. All entries designated as resistant did have some resistance compared to susceptible checks. Across all hybrids, grain yield was higher in sorghum with normal planting dates compared to late planting. Under midge pressure resistant hybrids performed better than susceptible hybrids, but lacking midge pressure the susceptible hybrids were higher performing. The use of midge resistant hybrids in commercial production is only warranted when producers are reasonably sure that midge will be a problem. Otherwise, they should continue to plant early using traditional hybrids.

MicroRNA (miRNA) plays a role in nearly all the biological pathways and therefore may provide opportunities to develop new means to combat the Hessian fly, Mayetiola destructor, a destructive pest of wheat. This study presents a comprehensive analysis of miRNA species via deep-sequencing samples from Hessian fly second instar larvae, pupae and adults. A total of 921 unique miRNA species were identified from approximately 30 million sequence reads. Among the 921 miRNA species, only 22 were conserved among Hessian fly and other insect species, and 242 miRNA species were unique to Hessian fly, the remaining 657 share certain sequence similarities with pre-miRNA genes identified from various insect species. The abundance of the 921 miRNA species based on sequence reads varies greatly among the three analyzed stages, with 20 exclusively expressed in adults, two exclusively expressed in pupae and two exclusively expressed in second instar larvae. For miRNA species expressed in all stages, 722 were with reads lower than 10. The abundance of the remaining 199 miRNA species varied from zero to more than eight-fold differences among different stages. Putative miRNA-encoding genes were analyzed for each miRNA species. A single putative gene was identified for 594 miRNA species. Two putative genes were identified for 138 miRNA species. Three or more putative genes were identified for 86 miRNA species. The three largest families had 14, 23 and 34 putative coding genes, respectively. No gene was identified for the remaining 103 miRNA species. In addition, 1516 putative target genes were identified for 490 miRNA species based on known criteria for miRNA targets. The putative target genes are involved in a wide range of processes from nutrient metabolism to encoding effector proteins. Analysis of the expression patterns of miRNA and pre-miRNA for the miRNA family PC-5p-67443, which contains 91 genes, revealed that miRNA and pre-miRNA were expressed differently in different developmental stages, suggesting that different isogenes are regulated by different mechanisms, or pre-miRNAs had other functions in addition to as an intermediate for miRNA biogenesis. The large set of miRNA species identified here provides a foundation for future research on miRNA functions in Hessian fly and for comparative studies in other species. The differential expression patterns between a pre-miRNA and its encoded mature miRNA in a multigene family is an initial step toward understanding the functional significance of isogenes in dramatically expanded miRNA families.

Abstract:
Oilseed rape (Brassica napus (L. )), the second most important arable crop in the UK after cereals, is attacked during the summer by cabbage seed weevil Ceutorhynchus assimilis (Paykull) and brassica pod midge Dasineura =brassicae (Winnertz). In mainland Europe, these two 'pests are known to be attacked by a range of hymenopteran parasitoids but virtually nothing is known about their parasitoids in the UK. This study found that the ectoparasitic Trichomalus perfectus (Walker) (Pteromalidae) was the most abundant species attacking C. assimilis, achieving, in unsprayed crops, levels of parasitism up to 73%. The egg-larval Platygaster subuliformis Kieffer (Platygastridae) was reared from D. brassicae for the first time and is probably a new species record for the UK; it was the most abundant species attacking the midge in winter rape. The endoparasitic Omphale clypealis (Thomson) (Eulophidae) was the most abundant species attacking D. brassicae in spring rape. The complexity of assessing parasitism in the multivoltine D. brassicae is discussed. In-field temporal and spatial distributions of hosts and parasitoids were studied using a novel randomization test and the results related to known biological characteristics of species. Using a new design of insect flight trap, P. subuliformis was shown to respond to 2-phenylethyl isothiocyanate and O. clypealis to 2-propenyl isothiocyanate, both volatile secondary plant compounds, produced by brassicaceous plants on damage. Field trials demonstrated that the post-flowering application of the organophosphate insecticide triazophos, has a detrimental effect on T. perfectus, killing adults and larvae, whereas the synthetic pyrethroid alphacypermethrin was less harmful because it was applied before the main migration of T. perfectus into the crop. The importance of the parasitoids ' of rape pests to integrated protection strategies for the crop are discussed.

Abstract:
This study investigates aspects of the biology of C. impunctatus with a view to producing an optimised laboratory culture of this species. Artificial membrane feeding of C. impunctatus is shown to be enhanced by the addition of blood vestiges to the outer surface of the feeding apparatus. The effects of holding temperature, environment and conspecific density upon oogenesis in blood fed female midges are assessed through mortality, digestion of the blood meal and development of the eggbatch over time. Oviposition in C. impunctatus is investigated through choice and nochoice bioassays which show Sphagnum spp. Mosses to be highly effective in this regard. Juncus articulatuslacutiflorus infusions also significantly increase the number of eggs laid by females in comparison to oviposition substrates used in colonisation of other midge species. Preliminary studies are also carried out to provide a suitable larval medium for colonisation purposes. The possibility of future colonisation is discussed with reference both to those experiments carried out, and to those areas not yet addressed in the C. impunctatus lifecycle. Dispersal of C. impunctatus is also examined, both on a local scale and in terms of gene flow between UK populations. Capture, mark, recapture studies showed the marked population of C. impunctatus remained relatively close to the release site in the habitat used for the study. The effect of prevailing winds, however, was found to be highly important in terms of passive directional movements of individuals. Daily survival rates of parous females were calculated as very low in relation to other species of midge making this species an unlikely candidate for pathogen transfer in Scotland. Polymorphism in the molecular markers used to examine gene flow in C. impunctatus across the UK was minimal and precluded phylogenetic analysis. This result is interpreted in terms of both possible long-distance dispersal and the effects of rapid post-glacial popUlation expansion into the UK.

Abstract:
El propósito del presente informe es analizar el riesgo de mercado teniendo en cuenta la materialización de las condiciones descritas en el Reporte de Estabilidad Financiera 2021-I. Para ello, se mide la transmisión de volatilidad que existe entre los mercados de deuda pública, deuda privada y acciones, de manera que se pueda identificar si un mercado, en determinado momento del tiempo, fue generador o receptor de volatilidad. Posteriormente, se estima el valor en riesgo (VeR) a un día del portafolio en posición propia de los tres mercados, así como los efectos de una posible materialización del riesgo de mercado sobre el balance de las entidades.

Full text
Abstract:
Este trabajo explica cómo los costos de comerciar (protección y otros costos) desestimulan las exportaciones manufactureras y por qué Colombia exporta mayoritariamente productos primarios. Para esto, además de una revisión de literatura y una descripción del desempeño exportador colombiano, se presenta una metodología que mide la protección total causada por el arancel y las medidas no arancelarias (MNA) y que permite generar una serie de la protección verdadera para el período 1950-2019. Los resultados muestran que el país no ha explotado su potencial exportador de manufacturas porque los incentivos para hacerlo han sido magros, un resultado de la alta protección a la producción local, de una infraestructura escasa y de unos servicios logísticos costosos.
