insect growth regulators and spinosyns which are physiologically and ecologically selective, respectively, have been investigated as replacements or complements to non-selective conventional insecticides. the effects of diflubenzuron, hexaflumuron, profenofos, spinosad and thiodicarb were assessed on the 1st instars of cotton bollworm, helicoverpa armigera (hã¼bner) using dietary and leaf disc ...

in vitro and greenhouse studies were conducted to investigate the possibility of an interaction between two systemic insecticides of: thiodicarb (larvin df 80) and imidacloprid (guacho sw 70), and seedling disease organisms of: rhizoctonia solani, fusarium moniliforme and pythium ultimum. when in vitro concentrations of imidacloprid and thiodicarb were applied, a fungistatic activity occurred. ...

The parasitoid Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) is often released to manage lepidopteran pests in cotton crops. However, growers rely on multiple insecticide applications pests. A harmonious integration of control tactics required for proper pest management, and the use selective insecticides (i.e., those promoting effective while causing little impact natural enemi...

Genetically modified (GM) soybeans expressing Cry1A.105/Cry2Ab2/Cry1Ac (event MON 87701 × 89788 87751 87708) and Cry1Ac 89788) from Bacillus thuringiensis Berliner (Bt) are valuable technologies for managing key lepidopteran pests of soybean in South America, but do not provide stand-alone protection against Spodoptera species. Here, we evaluated the use these Bt their integration with insectic...

The aphids Sitobion avenae (Fabricius) and Rhopalosiphum padi (Linnaeus) (Hemiptera: Aphidiae) are serious pests on grain crops and usually coexist on late period of wheat growth in China. Bioassays showed that R. padi was more susceptible than S. avenae to pirimicarb that is used for wheat aphid control, and the determination of acetylcholinesterase (AChE, EC 3.1.1.7) sensitivity showed that t...

A field trail Comprising of nine insecticides conducted at farmer’s in endemic area pests on cauliflower Siwan district Bihar during 2018-19.
