Повний текст джерелаCoccophagus rusti Compere, 1928 es un hymenóptero perteneciente a la familia Aphelinidae, que actúa como parasitoide de queresas. Esta especie fue introducida al Perú por Flanders en 1968 para el control biológico de Saissetia spp. (Hemiptera: Coccidae) en plantaciones de olivo. A pesar de su efectividad como parte del conjunto de controladores introducidos para el control de dicha plaga durante la década de 1970, en el Perú no se han realizado estudios sobre el ciclo biológico o la crianza de este parasitoide, bajo condiciones de laboratorio ni de campo, lo cual limita su empleo en el control biológico de plagas de cóccidos en nuestro país. Por tal razón el presente trabajo de investigación realizado durante las estaciones de primavera y verano de los años 2007 y 2008 en las instalaciones del Laboratorio del área de la Unidad de Producción de Insectos Benéficos de la Subdirección de Control Biológico (SCB) – Servicio Nacional de Sanidad Agraria en Vitarte, tuvo como objetivo determinar el ciclo biológico y la capacidad de parasitación de C. rusti bajo condiciones de laboratorio, como punto de partida para subsecuentes estudios e investigaciones. Los resultados sugieren que bajo condiciones controladas, el parasitoide es un eficiente controlador de la queresa S. coffeae.

Повний текст джерелаThe potencial of parasitism and the efficiency of Encarsia formosa on Bemisia tabaci were evaluated on collard green, tomato and soybean plants. The period of developmentof B. tabaci biotype B from egg to adult and the number of nymphs were evaluated on those plants. The ability of parasitism was evaluated by the number of daily parasitized nymphs and the total number of parasitized nymphs per female of E. formosa. The ideal number of parasitoids per plant was evaluated by releasing variable numbers of E. formosa on a fixed number of B. tabaci biotype B nymphs. The results were as follows: the duration of the egg to adult period of B. tabaci biotype B on tomato (22,03 days) was statistically superior to that on soybean (21,17 days), while this last one was significantly superior to that on collard green (19,8 days), under the same environmental conditions; the parasitoid showed preference to oviposit on the third and fourth instars of B. tabaci biotype B nymphs; the number of parasitized nymphs on collard green was higher than those observed on soybean and tomato, whereas the numbers on these last one did not differ; no difference was observed as to the parasitoid longevity when third and fourth instar nymphs were offered on the tested plants; however one observe a significant difference in the mean number of parasitized nymphs; on collard green plants eight parasitoids per plant resulted in a good control of this insect pest.

The systematic analyses and studies of host-parasitoid inter -actions of ~u2;Aphis~u1; ~u2;gossypii~u1; andAphelinus~u1; ~u2; mali~u1; were under- taken in this study by using the concepts and methods of Systems analysis. A series of experiments were conducted to determine the effect of parasitization by parasitoid ~u2;A.~u1;u2;mali~u1; on the demographic processes for host popu -lation of ~u2;A.~u1;u2; gossypii~u1;. The development and re- production of aphids after being parasitizedin different age intervals were compared with unpara- sitized aphids. The parasitizing effect of ~u2;A. ~u1;u2;mali~u1; become distinct at day 3 after parasitization. The effects of parasiti- zation on the development and reproduction of host aphids were related to the aphid age attacked: when the first and 2nd day old young nymphs had been parasitized by the parasitoid, the parasitized- aphids were killed by mummification before reached adult stage, however, the nymphs could develop to adult stage and to produce offsprings when had being parasitized in the older 3rd and 4th day old ages.

The parasitoid, Aphelinus gossypii, can both parasitize and feed on its host aphids. It is an important natural enemy in regulating cotton aphid population. In this study, we investigated the population fluctuations of aphid parasitoids on three different plants (Psidium guajava L., Ageratum houstonianum Mill., Bidens pilosa L.), and compared the developmental time and functional responses of A. gossypii among the three different plants. The species composition and population densities of parasitoids were distinctively different among the three different plants. There were 5 species of primary parasitoids collected on P. guajava, among them, A. gossypii was the most abundant. Its population density reached the highest level in November, and then dropped to the lowest level from May to September. A positive correlation was detected in the density fluctuations between A. gossypii and the cotton aphid on P. guajava(R2=0.2951,p=0.0184). Three species of primary parasitoids were found on A. houstonianum, of which, Aphelinus sp. was the most abundant. Its population density reached the highest level from January to March. Temperature showed a positive correlation in the density fluctuation of Aphelinus sp. on A. houstonianum(r=-0.8722,P=0.0002). On Bidens pilosa, two primary parasitoids, Aphelinus spp. were detected, but bolt were present at a very low level with only 14 individuals collected. There were significant differences in developmental time of A. gossypii on the three different host plants. The developmental time from parasitization to mummification was the shortest on P. guajava at 5.63 days, and the longest on B. pilosa at 6.8 days. The developmental time from mummification to adult emergence was the shortest on A. houstonianum at 6.4 days, and the longest on B. pilosa at 6.8 days. The total developmental time from parasitization to adult emergence was the shortest on P. guajava at 12.3 days, and the longest on B. pilosa at 13.7 days. At 25℃, a single female of A. gossypii was exposed to the cotton aphid at eight different densities (2, 4, 8, 16, 32, 64, 128, 160 per leaf disk) on three different plants for 24 hours, to determined its effectiveness in host feeding . The number of the cotton aphids fed by A. gossypii increased with the increase of aphid density. A. gossypii showed a Type Ⅱ functional response. The host-feeding number reached the upper limit when aphid density at 160 aphids per leave (5.75 aphids fed on A. houstonianum, 8.75 on B. pilosa, and 6.88 on P. guajava). The parasitized aphid number reached the upper limit at aphid density of 128 aphid per leave (25.13 aphids parasitized on A. houstonianum, and 38.13 on P. guajava). The aphids parasitized on B. pilosa reached the upper limit (25.5 aphid per leaf) when aphid density increased to 160 aphids per leaf. The parasitized aphids by A. gossypii also showed a Type Ⅱ functional response type. The number of aphids consumed reached the upper limit when the aphid density at 128, 160 and 128 aphids per leaf (29.88 aphids consumed on A. houstonianum, 34.25 on B. pilosa, and 44.38 on P. guajava). The curve of consumed aphids by A. gossypii showed a Type Ⅱ functional response. Although A. gossypii showed a better performance both in predation and parasitism to cotton aphid on P. guajava, the parasitoid also has a high potential controlling the cotton aphids on the two different weeds.

Chalcidoids are the most diverse group consisting of 22,000 described species in Hymenoptera. It is estimated that their total diversity could be from 60,000 to more than 500,000 species. Among them, the family Aphelinidae are smaller than average size (1.5 mm or less), containing 1,224 species in 32 genera. In spite of their small numbers, aphelinid parasitoids are major biocontrol agents of economically important pest species belonging to the hemipteran groups of coccoids, aphids and aleyrodids. However, the taxonomy of Taiwan aphelinids has not been established and poorly studied. Furthermore, since Dalman (1820) referred one Entedon species to the genus Aphelinus, no fewer than 102 genera were originally described in this family. Only since the middle of the 20th century did scientists begin vigorous attempts to study the types of described genera; this led to a drastic reduction in the number of genera to 32. However, the complex morphological features and complicated slide mounting make aphelinids as an extremely unpleasant and difficult group to study taxonomically. In this study, we provide a convenient, pellucid and permanent mounting method for aphelinids, and use plenty morphological drawings to make taxonomists feel easier to study these tiny insect groups. From 2008-2016, according to the collections and foreign academic exchanges, we provided a reliable key and revised Taiwan aphelinids, which currently include 108 species of 10 genera, including 7 new species and 25 new recorded species. The data shows a great biodiversity of Taiwan aphelinids because of the unique island with varied crops, plants and climate. We believe we can use these data to study the association between parasitoids, host insects and host plants in the future. This revision is just a beginning in that direction.

A collection of whiteflies of Bemisia and their Encarsia parasitoids was made during 2005~2006 in Taiwan. All of the Encarsia materials belong to the subfamily Coccophaginae (Hymenoptera: Aphelinidae). In this study, 1233 parasitoids reared from different whiteflies and 400 slide-mounted specimens were preserved in the Taiwan Agricultural Research Institute (TARI). Based on an analysis of these specimens, 19 species belonging to Encarsia from Bemisia were described and illustrated along with data of whitefly hosts and distribution. They include 13 recorded species, namely E. aseta Hayat & Polaszek, E. azimi Hayat, E. cibensis Lopez-Avila, E. duorunga Hayat, E. inaron (Walker), E. japonica Viggiani, E. longifasciata Subba Rao, E. lutea (Masi), E. obtusiclava Hayat, E. protransvena Viggiani, E. sophia (Timberlake), E. strenua (Silvestri), and E. synaptrocera Huang & Polaszek; four new species, namely E. atricornis sp. nov., E. guangxina sp. nov., E. lineolata sp. nov., E. maglusalae sp. nov.; and two new records of species from Taiwan, namely E. fuzhouensis Huang & Polaszek and E. perniciosi (Tower). All specimens described are preserved at National Taiwan University, Taipei, Taiwan. Collecting methods depended on whether the whiteflies were collected in the field or were reared indoors. Furthermore, a key to species of Encarsia from Bemisia is provided along with detailed illustrated figures.

Resistance to cotton aphid, Aphis gossypii Glover was compared among muskmelon (Cucumis melo L.) cultivars, Tainan 8 (TN.8), Tainan 9 (TN.9) and Autumn favor (C.T.), to assess the possibility of controlling cotton aphid by using aphid- resistant cultivar and parasitoid, Aphelinus mali Haldeman. Results revealed that TN.8 was the most susceptible cultivar, while TN.9 and C.T. were resistant with antibiosis effect of the development and reproduction of cotton aphid by no choice test. In free choice test, the highest population score was found on TN.8 for each aphid colony, and the lowes was on TN.9 at 5 days after aphid released. Results from these two tests suggested that TN.9 was more resistant that C.T.. Both of them could delay the population increment of cotton aphid with antibiosis and antixenosis. The influence of preconditioning host cultivars showed significant difference among various aphid conlonies which tamed from three different mudkmelon cultivars, respectively. on the longevity and body weight of apterous adult when tested on C.T., number of progeny produced per adult on TN.8, and survival rate of progeny on all cultivars. Host conditioning influenced antixenosis of C.T. by exhibiting the same level as Tn.9 when tested with preconditioned aphid colony of TN.8. but was lower than TN.9 when tested with the other two colonies, and the odor preference to host plant cultivars. Population growth ofsypii in field showed the slowest on TN.9, may delay the population increment of the cotton aphid. Aphid-resistant muskmelon cultivars had no negative impact on A. mali. No matter the host aphids werer from aphid-resistant or suscceptible mudkmelon cultivars.Resistant cultivars may complement the activity of the parasitoid in reducing cotton aphid. The compatibility between aphid-resistant mudkmelon cultivars and parasitoid is good, therefore, it can be incorporated in the integrated pest management program for controllong the cotton aphid population on muskmelon.

Повний текст джерелаThe soybean aphid (Aphis glycines) has become the most important pest of soybean in North America. Despite their efficiency, insecticides do eliminate the pest only for short periods and several applications may be required during the growing season. Furthermore, they are detrimental for the environment and human health. Biological control appears as a promising alternative for the control of A. glycines populations in North America. Three parasitoid species (Binodoxys communis, Aphidius colemani, Aphelinus certus) have been identified as potential candidates. The objective of this study was to study some biological attributes of these parasitoids in Québec. For B. communis and A. certus we examined their seasonal activities and their cold hardiness in laboratory and natural conditions. For A. colemani, we evaluated its capacity to parasite the soybean aphid and to disperse in soybean fields. Our results revealed that the B. communis strain we used had lost its capacity to enter diapause, probably due to the long period of laboratory rearing following its sampling in Asia. Aphelinus certus showed an interesting potential because the species is synchronized with its host both in the fall and the spring and has the capacity to overwinter in Québec. For A. colemani, the essays suggest that it disperses rapidly out of the field without attacking significantly A. glycines.

The silberleaf whitefly, Bemisia argentifolii, was reared on poinsetiia under barious constant temperatures. The highest survival rate from egg to adult were observed at 25C and 28C The low temperature thresholds for the development of egg , 1st,2nd, 3rd, and 4th instar nymphs were 12.7, 14.8, 10.4, 10.6, and 17C,respectively. The parasitoid wasps, Eretmocerus orientalis, were reared on third instar nymph of this whitefly. Survival rates of immature stages increased with the raise of temperature from 20C to 30C. The development periods shortened from 20C to 33C. The low threshold temperature for the development of egg to adult was 10.8C. E. orietalis preferred to oviposit on the whitefly nymphs of the third instar and feed on those of the first instar. The population densities of B. argentifolii on potted poinsettia on green houses at TARI and pipe houses at puli from 1993 to 1995 were surbeyed.

The objective of this study was to observe the relationship between the silverleaf whitefly (Bemisia argentifolii Bellows & Perring), and its two parasitoids, Eretmocerus orientalis Silverstri and Encarsia transvena Timberlake. Parasitism, host feeding, survival rate, development time, longevity and fecundity were recorded. The two aphelinids parasitized all instars of B. argentifolii; however, 3rd instars had the highest percentage of parasitism (55.84﹪) by E. orientalis, and 3rd instars had the highest percentage of parasitism (44.4﹪) by E. transvena. The two aphelinids can not complete development at 15℃. The survival rates of E. orientalis were above 80﹪at 20-30℃, and of E. transvena were above 82.4﹪at 25-30℃. The longest developmental periods of E. orientalis was 23.4 days at 20℃, the shortest was 13.2 days at 30℃. The longer developmental periods of E. transvena were at 20℃ (27.4 days) and 25℃ (25.5 days). At 30℃, E. orientalis and E. transvna had the fastest development rate. The highest longevity of E. orientalis and E. transvena were at 25℃ and 28℃. The highest fecundity of E. orientalis was at 28℃ (93.4 eggs), the smallest fecundity was at 15℃ (8.6 eggs). The highest fecundity of E. transvena were at 25℃ and 28℃, the lowest fecundity was at 15℃ (5.6 eggs). The higher amount of B. argentifolii 3rd instar nymphs killed by E. orientalis host feeding were at 20℃(31.0) and 25℃(36.4). The larger amount of B. argentifolii 3rd instar nymphs killed by E. transvena host feeding were at 25℃(54.2 ) and 28℃(57.0). When supplied with 40 whitefly 3rd instar nymphs, the wasps deposited more eggs, E. orientalis deposited 72.2 eggs and E. transvena deposited 59.6 eggs. The longest longevity of E. orientalis was 8.3 days at 40 nymphs, the shortest was at 10 nymphs. The longest longevity of E. transvena was10.1 days at 40 nymphs.

Results of the effects of temperature on the development of Encarsia pergandiella Howard show that the developmental time from egg to adult was the shortest (11.8 days) at 32℃ and was the longest (26.45 days) at 16℃. Thermal summation from egg to adult was 333DD. E. pergandiella caused mortality to its host, Bemisia argentifolii Bellows & Perring, through parasitization and host-feeding. The primary behavioral pathway for E. pergandiella to successfully oviposit and feed on B. argentifolii nymphs was searching, antennation (drumming), probing, host-feeding and grooming. At 24℃, the adult longevity of E. pergandiella was the longest, at 16.07 days, when provided with B. argentifolii nymphs and the shortest at 4.57 days when not provided any food. Fecundity of E. pergandiella female decreased with the increase of the oviposition time. The number of hosts fed by E. pergandiella females decreased with the increase of the host-feeding time. The total fecundity per female was 78.8 and the total number of hosts fed per female was 36.65. The functional responses of E. pergandiella females were examined at 5 temperatures (16、20、24、28 and 32℃), and each at 8 different host densities of 3rd instar nymphs B. argentifolii. The number of parasitization, host-feeding and consumption by E. pergandiella females were increased with the increase of the density of the host. When the host density was at 128, the maximum number of host parasitized was 2.5 at 16℃, 17.17 at 20℃, 25.83 at 24℃, 26.25 at 28℃ and 19.67 at 32℃. Under the same number of the host, the maximum number of hosts fed was 6.67 at 16℃, 8.50 at 20℃, 13.42 at 24℃, 15.33 at 28℃ and 12.33 at 32℃. Also under the same number of the host, the maximum number of hosts consumed was 9.17 at 16℃, 25.58 at 20℃, 39.24 at 24℃, 41.58 at 28℃ and 31.17 at 32℃. The type II functional response curves raised with the increase of temperature, except at 32℃. A higher proportion of E. pergandiella females left the leaf at lower host density, and the proportion increased with the increase of temperature. The studies showed that the developmental time and the functional responses varied significantly at each of the 5 temperatures tested.

Повний текст джерелаBuilding upon an existing aphid population dynamics model, we develop a method to quantify the contribution of parasitoids in reducing the maximum aphid density. We validated the method, over a two years study in soybean fields, using the biological model made of the soybean aphid (Aphis glycines Matsumura) and Aphelinus certus Jasnosh, its most abundant parasitoid in north-eastern North America. The method estimated that natural populations of A. certus reduced peak soybean aphid densities by only 1-6%. The cause of this low regulation is associated to the late establishment of A. certus population in soybean field, although the underlying mechanisms remains unknown. Proportion hyperparasitism on A. certus, before peak soybean aphid densities, were too low for hyperparasitism to be accounted for the poor efficacy of A. certus in regulating the soybean aphid. Regarding aphid population dynamics, we proposed a re-parameterisation of the aforementioned model to facilitate the interpretation of its parameters when field colonization by aphids is not simultaneous. This allowed us to identify a high predictability in peak aphid densities from colonization time for the soybean aphid. We recommend using models to forecast peak aphid densities and to use the impact assessment method to incorporate augmentative parasitoid release strategies into aphid management programmes.
