Peanut pod borer caused by Etiella zinckenella is one of the important pests of peanut in Indonesia. The symptoms of E. zinckenella attack are blackened pods and rotten seeds, causing yield loss up to 90%. The research aim was to validate the efficacy of various control technology components of peanut pod borer pests. The research was conducted at the Natar (Lampung) experimental station from April to August 2014. The research was arranged using a complete randomized design (CRD) method, the treatment consisted of six control technology components, and treatment was repeated four times. The results showed that the more larvae found in the pods, the greater the damage of the pods are crushed by larvae. Application of lambda cyhalothrin insecticide (P6) starting at 35–70 days after planting (DAP) was not able to suppress larval populations of E. zinckenella so that damaged pods were also larger and not significantly different from without control (P0). Lamda sihalotrin insecticide application also harms the survival of natural enemies (predators and parasitoids). Lamda cyhalothrin insecticides can be combined with other control components such as soybean trap plants, thiametoxam and carbofuran and parasitoid of Trichogramma bactrae-bactrae to control of peanut pod borer. Application of Lecanicillium lecanii biopesticide was combined with chemical insecticides thiametoxam or carbofuran can suppress E. zinckenella larvae and yield loses, beside it can safety against the survival of predators the order Araneida and Coleoptera and parasitoid of Hymenoptera and Diptera. Biopesticides of L. lecanii were combined with tiametoxam or carbofuran insecticides can be recommended for control agents of peanut pod borer E. zinckenella.

Context: Lamda cyhalothrin and neem seed extract can protect chickpea by controlling pod borer Helicoverpa armigera (Hubner).   Objective: To find out the effect of neem seed extract and lambda-cyhalothrin application schedule for the effective and economic management of pod borer attacking chickpea. Materials and Methods: The experiments were conducted in High Barind Tract of northern Bangladesh with the application of neem seed extract @ 50 g-l (two and three spraying) and lambda-cyhalothrin. (Karate 2.5 EC) @ 2 ml-l (two and three spraying) and untreated control. The seeds of BARI-Chola 5 chickpea were sown in rows with the spacing of 40 cm. At maturity, all the pods were collected from 10 randomly selected plants from middle rows of each plot. The damaged (bored) and total numbers of pod were counted. The grain yield loss (kg-ha) and percent pod damage were determined. The seed yield of each treatment was converted to kg-ha.   Results: The lowest pod damage (2.55%) as well as grain yield loss (34.90 kg-ha) were observed in the treatment where lamda cyhalothrin applied three times at 7 days interval from flowering stage. Chickpea seed yield was maximum (1338 kg-ha) with lamda cyhalothrin sprayed thrice which was identical to sprayed twice (1280 kg-ha). Neem seed extract showed a marginal performance to control chickpea pod borer. The highest marginal benefit cost ratio (3.19) was recorded from lamda cyhalothrin sprayed twice.   Conclusion: Lamda cyhalothrin double sprayed with 7 days interval from pod formation stage is the best package in managing pod borer in chickpea considering efficacy and profitability.   Keywords: Chickpea; pod borer; pod damage; pesticides; yield.

Trunk injection with Imidacloprid to control the palm aphid The injuries caused by the palm aphid, Cerataphis lataniae, on coconut plants may provoke economic losses. Thus, insecticide injection into the tree can provide protection and control against this pest. Our goal was to evaluate the efficiency of injection of imidacloprid on coconut trees to control the palm aphid. The experiment was carried out at the Lemos Maia experimental station, Ceplac, Una, Bahia, Brazil. The treatments applied were: 1) injection of 10 mL of the commercial product Provado® 200 SC (2 g i.a imidacloprid) in the stipe; 2) injection of 20 ml of Provado® 200 SC diluted in water (1 g i.a imidacloprid) and; 3) control (without insecticide application). The experiment was installed in a completely randomized design, with 15 replications, using leaf number 4 as samples. The parameters analyzed were number of aphids at 3 and 9 months after insecticide application and the number of leaflets/leaves with aphids at 26 months after application. The means were compared by the F and Tukey test at 5% probability level. All data were transformed into a log (x + 1). The aphid number and the number of leaflets per leaf infested with the aphid was higher in the control treatment. Thus, the application of imidacloprid via injection provided protection to coconut plants to the palm aphid, C. lataniae, until 26 months.

Survey, monitoring and documentation of entomofauna of cocoa was carried out in three cocoa growing states viz., Tamil Nadu, Kerala and Andhra Pradesh during 2014-2015. Results revealed that a total number of 23 species of insect pests and 13 species of natural enemies were documented and identified. Among the insect pests, 14, 2 and 7 species were sucking pests, borers and defoliators, respectively. Among the natural enemies, 7 species of predators and 6 species of parasitoids were documented and identified on different insect pests of cocoa. Among the insect pests, sucking pests were found to be predominant and maximum number of entomofauna were recorded in major coco growing areas of Tamil Nadu. From the results it was concluded that the list of entomofauna documented can enhance the knowledge on diversity of the entomofauna associated with cocoa in three different cocoa growing states. Sucking pests were found to be predominant and caused huge yield loss in Tamil Nadu and Kerala. While in Andhra Pradesh pod borer and bark eating caterpillar were found to be predominant causing severe yield loss. This information provides a base for development of location specific Integrated Pest Management module.

The experiment was accomplished to evaluate the bioefficacy of different insecticides against Mylabris phalerata (Pallas) on pigeonpea. The experiment consisted of seven treatments viz., bifenthrin 62 g a.i. ha-1, lambda-cyhalothrin 24 g a.i. ha-1 (encapsulated with polymers; Matadore), chlorpyriphos 310 g a.i. ha-1+ cypermethrin 31 g a.i. ha-1, cypermethrin 62 g a.i. ha-1, neem oil 1500 ppm, permethrin 154 g a.i. ha-1, chloropyriphos 173 g a.i. ha-1 compared with untreated (control). The sixth day after each spray, minimum population abundance of M. phalerata and maximum percent efficacy in reducing their population was obtained from bifenthrin which was at par with lambda-cyhalothrin, cypermethrin, chlorpyriphos+ cypermethrin and permethrin and all these were significantly effective over chloropyriphos, neem oil and control plots. On the tenth day after each spray, minimum population abundance and highest per cent efficacy were obtained from bifenthrin which was at par with lambda-cyhalothrin and both these treatments were significantly superior over rest of the treatments. The maximum productivity was observed with bifenthrin, while highest net return per rupee investment was obtained from lambda-cyhalothrin treatment. The results explicitly show that out of all treatments, Lambda-cyhalothrin was effective and imposing lucrative against M. phalerata and thereby minimized the yield loss. Three sprays of lambda-cyhalothrin and bifenthrin with an interchange at ten days interval will be effectual and lucrative against M. phalerata in short duration pigeonpea crop.SAARC J.

An alternative for the population suppression of Spodoptera frugiperda is the use of toxic baits. The objective of this study was to evaluate the dietary preference and toxic effect of insecticides associated with the attractiveness of S. frugiperda adults as a pest management method. The following attractions were tested: 1) 5% sucrose solution, 2) 10% sugarcane syrup, 3) 10% honey, 4) 5% hydrolyzed protein, 5) Noctovi® 43sb, 6) Noctovi® OVI PLU 1-3, 7) Noctovi® OVI PHE/PAL 50-50 in the study with choice. Attractions: 1) sugarcane syrup 10%, 2) Noctovi® 43sb, 3) Noctovi® 43sb + sugarcane syrup 10%, 4) Noctovi® OVI PLU 1-3 in the study with no chance of choice. For the toxicity study, the food attraction associated with insecticides was used: methomyl 2%, lambda-cyhalothrin 1%, chlorpyriphos 2%, spinosad 1%, chlorantraniliprole 2% and chlorfenapyr 2%. The experimental design was the completely randomized design (CRD) with chance of choice, without chance of choice and toxicity. The following parameters were evaluated: number of insects that fed; time in minutes that remained in the attractive food and mortality. The molasses (10%) and Noctovi® 43sb food attractiveness were significantly more efficient in relation to feeding time and the highest number of landings was observed in the Noctovi® 43sb treatment, both in females and total adults. Methomyl, lambda-cyhalothrin and spinosad insecticides associated with food attractiveness are promising toxic baits for the management of S. frugiperda.

AbstractBiological control plays an important role in many integrated pest management programmes, but can be disrupted by other control strategies, including chemical and cultural controls. In commercial cranberry (Vaccinium macrocarpon Aiton; Ericaceae) production, a spring flood can replace an insecticide application, providing an opportunity to study the compatibility of the flood (a cultural control) with biological control. We suspect that chemical controls will tend to reduce the number of natural enemies, while the flood, through removal of detritus and detritivores, may cause generalist predators to prey-switch to consume proportionally more pest individuals. We measured the abundance of herbivores (Lepidoptera), detritivores, Arachnida, and parasitoids (Hymenoptera) every week for six weeks in Wisconsin (United States of America) cranberry beds following either an insecticide spray or a cultural control flood. We found that detritivore populations rapidly declined in both flood and spray treatments; conversely, carnivore populations (spiders and parasitoids) were more abundant in the flooded beds than in sprayed beds. Populations of key cranberry pests were similar between flooded and sprayed beds. Our results showed that early-season flooding preserved more natural enemies than an insecticide application. This increase in natural enemy abundance after the flood may allow for greater continuity in herbivore suppression, potentially providing a basis for long-term cranberry pest management.

ABSTRACT The use of pesticides in the soybean crop may impair the biological control, if the products are not selective to Telenomus podisi and Trissolcus basalis, which are important stink bug egg parasitoids. This study aimed to assess the selectivity of 15 pesticides registered for soybean crop on adults of T. podisi and T. basalis. Three laboratory bioassays were performed, totaling 18 treatments, in a completely randomized design, with four replications. The insecticides (g or mL of a.i.) imidacloprid + beta-cyfluthrin (0.25 + 0.03), deltamethrin (0.06), thiamethoxam + lambda-cyhalothrin (0.27 + 0.35), acephate (1.87) and fenitrothion (1.25) are harmful to both parasitoids species. Flubendiamide (1.20), diflubenzuron (2.00), Bacillus thuringiensis (0.08) and lufenuron (0.12) are innocuous to both parasitoids. The fungicides azoxystrobin + flutriafol (0.31 + 0.31), trifloxystrobin + prothioconazole (0.37 + 0.44), pyraclostrobin + metconazole (0.33 + 0.12) and trifloxystrobin + cyproconazole (0.94 + 0.40) are innocuous to T. podisi, but slightly harmful to T. basalis. The herbicides glufosinate ammonium salt (0.50) and glyphosate isopropylamine salt (1.20) are innocuous to both parasitoids.
