Evaluation of new and conventional insecticides for the management of mustard aphid, Lipaphis erysimi Kalt. (Homoptera: Aphididae) on rapeseed (Brassica juncea L.)
... 17.8% SL at 27g a.i/ha, lambda-cyhalothrin 5% EC at 25g a.i/ha, chlorpyriphos 20% EC at 375g a.i/ha, dichlorvos 75% EC at 375g a.i/ha, thiamethoxam 25% WG at 27g a.i/ha, dimethoate 30% EC at 375g a.i/ha and chlorpyriphos 50% + cypermethrin 5% EC (Canon) at 375g a.i/ha. Chlorpyriphos (93.50%) found to be most effective treatment followed by chlorpyriphos + cypermethrin (92.76%), thiamethoxam (90.70%) and imidacloprid (90.46%) and dichlorvos (82.81%) showed lea...

...ollowed by abamectin and lambda-cyhalothrin. While among the botanicals, Azadirachta indica, Citrullus colocynthis and Nicotiana tabacum caused the most significant reduction of okra borers in both years, followed by Curcuma longa and Corymbia citriodora. These synthetic insecticides and botanicals on average reduced okra fruit infestation by 20 to 56% and by 18 to 10%, respectively, and increased okra fruit yield up to 45%. We ther...

...rations of insecticides (lambda-cyhalothrin, cypermethrin, thiamethoxam, imidacloprid, profenophos and chlorpyriphos) significantly affected the IGP of coccinellids beetles and their aphid consumption. The effect of insecticides was concentration dependent.None of the tested insecticides was found completely harmless to coccinellids. Imidacloprid was found relatively safe to coccinellids and hence, recommended for use in canola field. It is concluded that C...

These insecticides were frequently being used to control different insect pests of major crops in Punjab-Pakistan. The experimentation was performed under laboratory conditions (28±2°C and 65±5% R.H). Four different concentrations (i.e. 50 ppm, 100, 200 and 400 ppm) of each insecticide were evaluate...

Based on overall study results, the insecticidal formulations of spirotetramat, lambda-cyhalothrin and sulfoxaflor in combination with EPF and under-canopy hoeing are recommended to the local citrus growers for an effective control of D. mangiferae infestation. ...

Adverse Effect of Sublethal Concentrations of Insecticides on the Biological Parameters and Functional Response of Predatory Beetle Coccinella septempunctata (Coleoptera: Coccinellidae) of Brassica Aphid
...ontrol. Thiamethoxam and lambda-cyhalothrin non-significantly reduced the coccinellids larval weight. Type II response was shown by larvae of C. septempunctata in control treatment. Larval coccinellids showed type II functional response after feeding on the brassica aphids (Brevicoryne brassicae) treated with thiamethoxam, lambda-cyhalothrin and cypermethrin, while imidacloprid, profenophos and chlorpyrifos treated aphids al...

The bivalves were exposed to different concentrations of test pesticides in a static system. The MN frequencies of all the pesticide treated mussel groups increased significantly (p< 0.05) until the end of the exposure period as compare to control. The highest MN frequencies were recorded af...

Significant (p< 0.005- 0.00) decreased in total protein was noted in response to all the pesticides as compared to control group and a slight increase was also noted during 48 h as compared to 24 h.

Higher concentrations of abamectin (6000 ppm), chlorpyrifos (12000 ppm) and chlorantraniliprole (700 ppm) showed 100% larval mortality at 24 h post-exposure. Lambda-cyhalothrin (3500 ppm) showed 95% larval mortality at 24 h and...
