Abstract (sommario):
AbstractMethyl parathion or Penncap M (an encapsulated methyl parathion) are used extensively throughout the United States for controlling stink bug pests in soybeans, Glycine Max (L.) Merrill. However, this insecticide is highly toxic to mammals, birds, and non-target arthropods, and thus is less environmentally sound than other insecticides. For environmental and human health considerations, investigating alternative insecticides for control is desired. For this investigation, research based on field experimental data from Florida, Georgia, and Louisiana during the 1988 and 1989 growing seasons were employed. Results indicate that alternative, currently available, and less toxic insecticides may reduce producer costs, increase yield, and improve soybean quality. These alternative insecticides include Scout (tralomethrin), Karate (lambda-cyhalothrin), Orthene (acephate), and Baythroid (cyfluthrin). In terms of improved profits these alternative insecticides may dominate methyl parathion or encapsulated methyl parathion.

Abstract (sommario):
Dengue is an infectious disease with high rates of morbidity and mortality, transmitted by the bite of the female mosquito of the genus Aedes aegypti, vector distributed in tropical and subtropical areas throughout the world. America is one of the most affected regions. This vector is controlled through insecticides that due to its constant use in populations, a resistance phenomenon has been produced. The objective of this review is to identify the situation of insecticide resistance in populations of Aedes aegypti in Latin American countries. In this region, several insecticides have been used for vector control; in the last 10 years insecticides of the pyrethroid and organophosphorus group have been used as adulticides for the control of the mosquito, conditioning resistance. Some insecticides such as organophosphates and deltamethrin, despite of not being intensively used in Latin American countries, also show resistance. Improvements in vector control are required, including the rotation of the insecticides during the different seasons, as well as innovating techniques and forms of vector control

Abstract (sommario):
Asiatic huanglongbing (HLB) is a devastating disease of citrus associated in North America with the bacterium ‘Candidatus Liberibacter asiaticus’ (LAS) vectored by the Asian citrus psyllid (ACP), Diaphorina citri Kuwayama. ACP management is considered a vital component of a program aimed at reducing the incidence and spread of HLB. Considerable research has been published comparing the efficacy of different insecticides for ACP control as well as on seasonal strategies for applying ACP insecticides. However, published information was largely lacking for even the most intense insecticide programs on their effectiveness for keeping HLB out of a new citrus planting in Florida citrus. We therefore conducted two replicated (individual plots 0.2 to 0.4 ha in size) experiments on protecting young citrus from HLB using different ACP management programs. An intensive insecticide program was evaluated in each experiment: eight annual calendar applications of traditional insecticides (hereafter referred to as the “complete” program). In one experiment, citrus was either planted alone and subjected to the complete program or citrus was interplanted with orange jasmine, Murraya exotica L. (a favored ACP host plant) and subjected to a reduced insecticide program (four calendar sprays of traditional insecticides). There was one set of plots in which both jasmine and citrus were treated with insecticides and one set in which jasmine was not treated at all. In the second experiment, citrus was either subjected to the complete program or to one of two other programs: a reduced insecticide program consisting of five calendar applications of traditional insecticides or a mineral oil program (oil applications every 3 weeks plus one dormant insecticide spray). The results of the two experiments were similar. Relatively good ACP control was achieved under each ACP management program during the first year but, as the experiments progressed and trees increased in size, ACP outbreaks occurred regardless of the psyllid management program. Little HLB developed under any ACP management program during the first year, but thereafter HLB increased and large percentages of the trees in each experiment became LAS-infected in less than two to three years. The combined results of the experiments indicated that up to eight monthly pesticide treatments per year applied on a calendar schedule were ineffective for preventing young citrus from becoming diseased. Of important significance is that the orchard within which the two experiments were conducted was subjected to a minimal psyllid management program and contained many older trees known to be infected by the HLB pathogen, a challenging situation for getting young trees into production without contracting the disease. Thus, the ACP management programs we evaluated might have been more effective if ACP in the surrounding areas had been more aggressively controlled and diseased trees in the surrounding areas removed to reduce inoculum loads. Also, the programs might have been more effective for slowing the spread of HLB if our research plots had been larger.

Abstract (sommario):
The stink bug Dichelops melacanthus has become an important pest for corn crop and it has been causing several losses even in the initial phase of the crop. The objective of the experiment was the evaluation of effectiveness of the insecticides on the control of D. melacanthus in corn by adding of sulfur or not, in different control times. In order to evaluate the effect of the insecticide by adding or not sulfur on the control of D. melacanthus, 17 treatments with 4 different insecticides (with and without sulfur, in two different control times plus control) were used to get the results. The experimental design used was the randomized blocks, with four repetitions. The evaluation of effectiveness on stink bugs control was gotten by visual evaluation of the symptoms at 6, 13 and 20 days after emergence (DAE). Analysis of variance by F test (Anova) was done and the averages compared through Scott-knott test (p≤0,05). The pulverization of insecticides was more effective when it was done 4 (DAE), reducing the symptoms and injuries occasioned by the stink bug D. melacanthus and the mortality of damaged plants. The insecticide bifentrina+carbosulfano showed the higher effectiveness on stink bug control. To conclude, the use of sulfur associated to insecticides did not present a significant effect.

Abstract (sommario):
Three series of new anthranilic diamide derivatives containing sulfide, N-cyanomethylsulfilimine, and N-cyanomethylsulfoximine groups were designed and synthesized by coupling the active substructures of anthranilic diamides and sulfoxaflor. The structures of the synthesized compounds were confirmed by infrared spectroscopy, 1H and 13C NMR, and elemental analysis. Several unique structural characteristics were revealed via the crystal structure analysis of compound N-(2-(2-methyl-2-(methylthio)propylcarbamoyl)-4-chloro-6-methylphenyl)-3-bromo-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-carboxamide 16e. Bioassay results indicated that most of the synthesized compounds showed superior insecticidal activities against Mythimna separata and Plutella xylostella when compared with the positive control cyantraniliprole. In particular, N-(2-(2-methyl-2-(N-cyanomethylsulfideimino)propylcarbamoyl)-4-chloro-6-methylphenyl)-3-bromo-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-carboxamide 17e showed excellent insecticidal activity against Mythimna separata, with a mortality rate of 100 % at a concentration of 1 µg mL–1. These results indicated that sulfide, N-cyanomethylsulfilimine, and N-cyanomethylsulfoximine moieties, as important active substructures, could improve or maintain the activity of the anthranilic diamide and promote novel pesticide development.

Abstract (sommario):
Okra (Abelmoschus esculentus L.) is susceptible to number of diseases like Yellow Vein Mosaic Virus disease, Damping Off, Fusarium wilt, Powdery Mildew and Enation Leaf Curl. The Okra is favorite host of whitefly which transmits the okra Yellow Vein Mosaic Virus (OYVMV). OYVMV disease causes considerable yield losses in Okra. Experiment was conducted to check the efficacy of organic matter (poultry manure, leaves) and insecticides (Acetamiprid, Diafenthiuron, Pyridine Carboxamide) against OYVMV and its whitefly vector. In this experiment, ten okra varieties were sown in randomized complete block design (RCBD). Organic matter and insecticides were applied at recommended doses (@5ml/L) on weekly intervals. Among insecticides, Acetamiprid showed the best result to manage whitefly infestation with 60.01% mortality and OYVMV disease severity with 53.98% efficiency. Polo (Diafenthiuron) also showed good results to manage whitefly (56.36%) and OYVMVD (46.34%), but Ulala (Pyridine Carboxamide) insecticide was least effective to control whitefly population (47.27%) and to manage the infection of OYVMV disease (43.91%). Leaf manure was more effective with 61.16% efficiency as compared to poultry manure (56.01%) against OYVMV disease severity. New chemistry insecticide (acetamiprid) gave the most effective control of whitefly and transmission of OYVMV and could be used in place of conventional insecticides. Leaf manure proved significant defense activator in okra plants with effective control of disease and could be used as eco-friendly management approach.

Abstract (sommario):
Abstract Selected insecticides were evaluated for sorghum midge control at the Texas Agricultural Experiment Station Research Farm near College Station, TX. Hybrid grain sorghum (ATx399 × RTx430) was planted 20 May in rows spaced 30 inches apart. Insecticide treatments were compared in plots, 8 rows × 40 ft long, arranged in a RCB design with 4 replications. Insecticides were applied to the middle 2 rows of plots. Insecticides were applied between 0800 and 0900 hours CDT by using a hand-held backpack sprayer with TX-3 hollow cone nozzles at 35 psi, producing a finished spray volume of 5.6 gpa. Application began when 10-30% of the panicles were flowering; insecticides were applied 10, 13, and 16 Jul. Adult sorghum midge abundance was determined just prior to each application by counting the number of sorghum midges on 10 individual sorghum panicles enclosed in clear plastic bags. The panicles were cut from the plant and returned to the laboratory for examination and sorghum midge counts. Grain yield data were collected from the 2 middle rows per plot. Panicles were hand harvested from selected 8.75 ft sections of row/plot and mechanically threshed. Data were statistically analyzed by using ANOVA and LSD.

Abstract (sommario):
In an attempt to find the neonicotinoid insecticides, twenty novel dihydropyridine derivatives were designed, “green” synthesized via one pot facile three-component reaction and evaluated for their bioactivities against Tetranychus cinnabarinus, Myzus persicae, Brevicoryne brassicae, Fusarium oxysporum f. sp. vasinfectum, Magnaporthe oryzae, Sclerotinia sclerotiorum and Botrytis cinereal. All of the tested compounds showed potent insecticidal activity, and some were much better in comparison with imidacloprid (IMI). Especially, compounds 3d (LC50: 0.011 mM) and 5c (LC50: 0.025 mM) were 12.2- and 5.4-fold more active than IMI (LC50: 0.135 mM) against T. cinnabarinus, respectively. Moreover, out of all the derivatives, compound 3d (LC50: 0.0015 mM) exhibited the strongest insecticidal activity against B. brassicae and compound 3i (LC50: 0.0007 mM) displayed the strongest insecticidal activity against M. persicae. Surprisingly, when the concentration of compound 4 was 50 mg/L, the inhibition rate against F. oxysporum and S. sclerotiorum reached 45.00% and 65.83%, respectively. The present work indicated that novel dihydropyridine derivatives could be used as potential lead compounds for developing neonicotinoid insecticides and agricultural fungicides.

Abstract (sommario):
The screening of suitable insecticides is a key factor in successfully applying trunk injection technology to ornamental plants. In this study, six chemical pesticides were selected and injected into the trunks ofOsmanthus fragransto control the nettle caterpillar,Latoia lepida(Lepidoptera: Limacodidae), using a no-pressure injection system. The absorption rate of the insecticides, the leaf loss due to insect damage, and the mortality and frass amount ofL. lepidalarvae were evaluated after 77 and 429 days. The results showed that 4% imidacloprid + carbosulfan and 21% abamectin + imidacloprid + omethoate had the fastest conductivity and were completely absorbed into the trunkswithin14 days; however, the efficiencies of these insecticides in controllingL. lepidawere extremely low. Additionally, the treatment 10% emamectin benzoate + clothianidin and 2.5% emamectin benzoate was almost completely absorbed within 30 days and exhibited a longer duration of insecticide efficiency (>80% mortality) in the upper and lower leaves of the canopy. Treatment with these insecticides also resulted in significantly lower leaf loss and frass amounts. We conclude that emamectin benzoate and emamectin benzoate + clothianidin have a rapid uptake intoO. fragrans, and are effective as insecticides over long durations. Hence, they may be a suitable control option forL. lepidainO. fragransplants.

No masked chafer larvae were observed for treatments of imidacloprid, imidacloprid plus bifenthrin, clothianidin, and the two higher rates of DPX-E2Y45. The inconsistent and low populations of masked chafer larvae and billbugs in the turfgrass did not provide for conclusive results. Clothianidin and the two higher rates of DPX-E2Y45 had no billbug larvae. An early rating date showed that more billbug adults were in turf treated with imidacloprid and DPX-E2Y45. Later rating dates showed a decline in adults for all treatments.

Abstract (sommario):
A single application of buprofezin (Applaud7) at 0.38 lb AI/A had the fewest number of adult whiteflies (WF) on rating dates at 13, 21, and 27 days after treatment (DAT). The number of immature WF at 21 DAT of a single Applaud application ranged from 0.8 to 5.2 nymphs/leaf, significantly less than the untreated. Applaud treatments were effective in minimizing the immatures for 21 DAT of a single application and then numbers began to increase before 27 DAT. Applaud plus two subsequent weekly applications of bifenthrin (Capture7) plus endosulfan (Thiodan7, Phaser7) was almost similar to single applications of Applaud alone and adult numbers were also low. Weekly applications of the pyrethroids plus endosulfan reduced the adult WF relative to the untreated at 1 week after treatment (WAT). At 2 WAT of the third application, fenpropathrin (Danitol7) and Capture continued to show reduced numbers of adults and esfenvalerate (Asana7) was similar to the untreated. Danitol treatments had numerically fewer adults than Capture which was lower than Asana. The lowest adult and immature WF populations were observed season-long in the CGA-293343 (Novartis) treated cantaloupes. Both rates, 0.067 and 0.09 lb AI/A performed similarly and numerically slightly fewer nymphs were observed for the higher rate. CGA-293343 plus CGA-215944 (pymetrozine, Fulfill7) performed similar to the two rates of CGA-293343 alone.

Abstract (sommario):
Several studies were conducted in the spring and fall 2001 to evaluate a number of neonicotinoid compounds (Admire, Calypso, Actara, Platinum and dinotefuron) for whitefly control in spring and fall melons. The results of these studies demonstrate that several insecticide products are being developed that offer melon growers management alternatives for controlling whiteflies. The new foliar neonicotinoid Calypso (thiacloprid), shows excellent promise as a foliar, post-planting spray with 14-21 day residual. Further, no consistent negative interaction was detected between Platinum and fertilizer, 10-34-0 and UN 32, applied together as at-planting or side dress soil treatments. These treatments provided good whitefly control, but further research is needed to replicate these effects as Platinum has been labeled at lower rates than the manufacturer initially anticipated. At planting applications of Platinum at 8 oz (current labeled rate) did however provide acceptable residual control of whiteflies on fall melons under heavy population pressure.

Abstract (sommario):
Genetically modified cotton (Gossypium hirsutum L.) acreage has increased dramatically over the last six years. Reports of variable results in fiber quality and yield have arisen in these cultivars. Some changes in production practices have occurred coincident with the introduction of transgenic technology, such as reduced use of broad-spectrum insecticides, including organophosphates (OP) that could potentially influence the growth and yield of cotton. One factor that might affect these parameters is the difference in the amount of foliarly-applied phosphorus (P) between an OP and non-phosphate (NP) insecticide regime. Therefore, a study was conducted to investigate selected growth characteristics, yield, and fiber quality of genetically modified and conventional cotton as influenced by OP and foliar phosphorus (FP) applications. A four replication strip-plot experimental design was utilized with cultivar serving as the whole plot and insecticide regime as the sub-plot. Three cultivars of the same recurrent parent (ST4892BR, ST4793R, and ST474) were planted in 2001 and 2002 under irrigated conditions in Burleson County, TX on a Weswood silty clay loam (fine-silty, mixed, thermic Fluventic Ustochrept). The insecticide regime consisted of NP, NP+FP, and OP treatments. The FP was applied at P2O5 weight equivalent to the P component in the concurrent OP application. ST4892BR had greater lint yield than ST4793R and ST474. The yield increase can be explained through plant mapping analysis which showed ST4892BR producing larger bolls and greater boll numbers. In addition, evaluation of fruiting distribution showed ST4892BR contained more lint on sympodial branches 6 through 10. The insecticide regime effect on lint yield resulted in higher yield (P=0.08) for the NP+FP regime. Examination of yield components revealed NP+FP increased second position bolls, predominantly at sympodial branches 6 through 10. Leaf tissue analysis revealed increased levels of P for the OP and NP+FP over that of the NP insecticide regime, which indicates a potential for plants to acquire P from OP insecticides. Furthermore, the considerable yield response to small amounts of FP is not clearly understood. While conclusive evidence exists regarding cultivar yield differences, this study does not provide sufficient evidence to conclude that OP insecticides influence growth, yield, or fiber quality characteristics of these cotton cultivars.

Abstract (sommario):
Cabbage moth is one of the main white head cabbage pests in Belarus. The evaluation of the existing insecticides assortment has shown that their application at the initial pest number from 0.72 to 4.0 caterpillars per inspected plant has allowed reducing cabbage moth harmfulness and number by 84.0–100.0 % and increasing heads yield up to 35.5 %.
