The investigations on “Grain yield and incremental cost benefit ratio (ICBR) biorational insecticides against Helicoverpa armigera in chickpea” were carried out at the Student’s Instructional Farm, C. S. Azad University of Agriculture Technology, Kanpur during Rabi season 2021-22 2022-23 with three replications eight treatments insecticides, armigera. like HaNPV, Nimbecidine, Bacillus thuringie...

We present the results of evaluating the response of three species of bees, Trigona fulviventris (Guérin), Scaptotrigona mexicana (Guérin-Meneville), and Apis mellifera (L.), to food sources baited with the toxic bait GF-120 (NF Naturalyte), a spinosad-based bait exclusively used to manage fruit flies. Groups of foragers were trained to collect honey and water from a feeder located 50 m from th...

Adult tomato psyllid, Bactericerca (Paratrioza) cockerelli (Sulc) (Homoptera: Psyllidae), behavioral responses were evaluated for five tomato plant lines and for the interactions of insecticides with four commercial cultivars. Plant lines tested included the commercial 'Shady Lady', 'Yellow Pear', '7718 VFN', 'QualiT 21', and the plant introduction line PI 134417. Insecticides included a kaolin...

The Arkansas recommendation for Heliothine control is to use the higher recommended rates when a cotton production area is under heavy Heliothine pressure (Greene, 2003). However, Heliothine resistance to pyrethroid insecticides has been documented several times in the past few years (Payne et al., 2001; Williams,1999). Tank mixing pyrethroids with non-pyrethroids has been shown to be effective...

We investigated whether development of resistance to a Bt crop in the presence of a natural enemy would be slower than without the natural enemy and whether biological control, in conjunction with a Bt crop, could effectively suppress the pest population. Additionally, we investigated whether insecticide-sprayed refuges of non-Bt crops would delay or accelerate resistance to the Bt crop. We use...

[reaction: see text] Spinosyn G was isolated in the late 1980s as a minor component from the broth of our potent, fermentation-derived insecticide spinosad. Its structure was then tentatively identified as 5' '-epispinosyn A (3) on the basis of (1)H and (13)C NMR data, but the 4' '-epi compound 4 could not be conclusively ruled out with the data available. Described herein are unambiguous synth...

) is one of the most important public health pests spread in Egypt, so we studied biochemical and toxicological changes to traditional bio-pesticides on third instar larvae domestic mosquito. Three organic pesticides (chlorpyrifos, lambada cyhalothrin, imidaclopride) two biopesticides (emamectin benzoate, spinosad) at different concentrations treated calculating value LC

Bioassays of Lacanobia subjuncta (Grote and Robinson) larvae established baseline LC50 values and identified the potential of reduced-risk, organophosphate replacement and naturally derived insecticides (eg chloronicotinyls, spinosyns, oxadiazines, insect growth regulators, microbial insecticides and particle films) to control this pest. The toxicities of these products were compared with those...
