This study investigated alternative in-field chemical controls against Bactrocera tryoni (Froggatt). Bioassay 1 tested the mortality of adults exposed to fruit and filter paper dipped in insecticide, and the topical application of insecticide to adults/fruit. Bioassay 2 measured the mortality of adults permitted to oviposit on fruit dipped in insecticide and aged 0, 1, 3, or 5 days, plus the pr...

Spodoptera exigua, which feeds on various crops worldwide, has natural enemies that are susceptible to the insecticides used against S. exigua. We investigate the toxicity and residue risk of 9 insecticides on the development of H. axyridis, C. sinica, S. manilae and T. remus. S. manilae and T. remus adults were sensitive to all 9 insecticides (LC50 less than 2.75 mg a.i. liter-1), while H. axy...

Laboratory and semifield bioassays were conducted to determine the life-stage activity of insecticides for controlling cranberry fruitworm, Acrobasis vaccinii Riley (Lepidoptera: Pyralidae), a key lepidopteran pest of highbush blueberry, Vaccinium corymbosum L. The organophosphates azinphosmethyl and phosmet, the pyrethroid esfenvalerate, and the carbamate methomyl were lethal to all life stage...

Tea is consumed throughout the world, both for pleasure and therapeutic purpose. Most people will be unaware of their involuntary exposure to residues of pesticide lingering in processed tea and so possibly transferring into infusion of tea. The objective of this trial was not only to provide a simple residue analytical method to evaluate the safe application rate of emamectin benzoate for tea ...

A field study assessed the efficacy of insecticides against pink bollworm cotton. Spinosad 45SC treated cotton had lowest infestation at 23.95% in first spray, while cypermethrin 25EC a 26.06% second spray. Emamectin benzoate 5SG and spinosad were most potent for locule damage reduction. 70.54% mortality 76.2% 5SG, 45SC, effective overall.

House flies, Musca domestica L., are important pests of dairy operations worldwide, with the ability to adapt wide range of environmental conditions. There are a number of insecticides used for their management, but development of resistance is a serious problem. Insecticide mixtures could enhance the toxicity of insecticides in resistant insect pests, thus resulting as a potential resistance m...

A field trial was conducted at Central Research Field, SHUATS, Naini, Prayagraj during rabi 2021 in Randomized Block Design (RBD). Seven treatments were evaluated against Lipaphis erysimi i.e., Imidacloprid 17.8% SL @ 0.5ml/lit, Thiomethoxam 25%WG 4 gm/lit, Neem oil 5ml/lit, Indoxacarb 14.5%SC@ 0.65 ml/lit, Emamectin Benzoate 5% SG, seed kernel extract (NSKE) 5 Spinosad 45% SC. Results revealed...
