“…The results of this study indicate that the chemical insecticide from lambda-cyhalothrin which was applied seven times was considered not able to suppress the development of E. zinckenella population because the pod damage was high and not statistically different from the control (P0). This result was in contrast to the research conducted by Gehan & Abdalla (2006) and Dhaka et al (2011) which stated that the lambda-cyhalothrin was quite effective for controlling E. zinckenella in cowpea. The difference in the efficacy of this study was probably due to the differences in the host plants of E. zinckenella.…”

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.

“…This has promoted the necessity for seeking new, safer, biodegradable insecticides that could be feasible and effective for insect pest management (Prasad and Purohit, 2013). Few researchers (Ahmed et al 2004;Ghosh et al 2010;Meena andRaju, 2014 andDhaka et al 2015) have stated that the different group of insecticide showed the great impact on incidence of this pest with single or low dose of insecticides.…”

To determine Incremental Cost-Benefit Ratio (ICBR) of certain bio-pesticides and insecticide against 2 nd larval instar of Helicoverpa armigera in chickpea, an experiment was conducted during winter 2011. Certain pesticides as sole treatments were tested with standard, low and high doses and in treatment combinations with one half of standard doses of two respective pesticides only once at 50% flowering and podding stage of the crop. Upon crop maturity; total grain yield, additional yield, increased income and net income were obtained for each respective treatment to determine its ICBR. Overall, the treatment combination of ½ Btk + ½ Azadirachtin had the highest ICBR of 1:27.57. The lowest ICBR of 1:5.25 was obtained with Azadirachtin-0.05 %, when other treatments had ICBR from 1:8.51 to 1:23.28.

“…Similarly Kumar et al (2014) indicated that Spinetoram 12% SC was significantly effective in minimizing E. zinckenella larval population on pigeonpea plants and increasing the grain yield. Dhaka et al (2011) showed that Spinosad, B. thuringiensis and Neemarin, was recorded the best yield comparable untreated control against E. zinckenella larval. Gehan and Abdalla, (2006) concluded that Chlorpyrifos was the superior compound being registered (45.9%) increase in yield over the untreated control value.…”

“…was proved superior activity against the larval population of pea pod borer as compared to other treatments. Dhaka et al (2011) showed that Spinosad, B. thuringiensis and Neemarin, were sprayed on vegetable pea against pod borer, E. zinckenella, had lower number of larvae as well as pod and seed infestation than untreated control. While, Adel and Maimoon (2006) recorded that Tracer 22.8%(a.i.…”

Field experiments were carried out in Tahla village, Qalyoubia governorate during two successive seasons, 2014 and 2015. The first experiment was conducted to study the effect of four planting dates of cowpea seeds (March, 20 th ; April, 10 th ; May, 1 st and May, 22 nd .) on infestation levels of cowpea pod borer, Etiella zinckenella (Treit.), and effect on yield of this crop. The degree of infestation by E. zinckenella significantly increased by delaying planting date. Cowpea plants cultivated in the earliest planting date (March, 20 th) was attacked by few numbers (2.3 & 1.5 larvae/10 pods during the two successive seasons, respectively), with the high weight of cowpea seeds (27.7 & 28.9 kg/ 100 m 2 during the two seasons, respectively). However, it was given the lowest number of both damaged pods and seeds. In contract the plants of the latest planting date (May, 22 nd) was more liable to insect infestation (9.0 & 15.3 larvae/10 pods during both two seasons, respectively), with the low weight of cowpea seeds (20.2 & 19.3 kg/ 100 m 2 during 2014 and 2015, respectively), Also, it was given the highest number of damaged pods and seeds. Therefore, it was concluded that the plant date was effective on infestation rate by this pest and yield of cowpea seeds and can be avoided by planting it as early as March, 20 th. The second experiment was studied the effect of some insecticides and their efficacy against lima bean pod borer, E. zinckenella of cowpea. The present results showed that the mortality percentage were arranged descending as Sumithion 50% EC (62 %), Tracer 24% SC (55.3%), Radiant 12% SC (53.4%), Neemix 4.5% EC (35.7%) and finally Dipel 2x 6.4% WP (33.7%), with significant differences between the tested treatments compared with control. Also, Sumithion was the superior compound in this respect being registered 53.8 % increasing in the yield over the control value followed by Tracer (43.2 %), Radiant (40.8 %), Neemix (19.7 %) and Dipel 2x (12.7%).
