The experiment was conducted at the research plot of Department Agricultural Entomology Central Research Field, Sam Higginbottom University Agriculture Technology and Sciences, Prayagraj, India, during Rabi season 2022. treatments selected for this were Emamectin benzoate, Beauveria bassiana, Spinosad, Heterorhabditis indica, Metarhizium anisopliae, HaNPV, Bacillus thuringiensis control to obse...

Abstract The Egyptian cotton leafworm Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) is a pervasive agricultural polyphagous insect pest. Because of the negative side-effects conventional pesticides used in fields, safer alternatives for pest management are required. We evaluated here susceptibility, biological features, and nutritional indices S. after treatment 4 th -instar larvae...

Since chemical pesticides have a variety of short- and long-term social, economic, environmental repercussions, research was conducted in Baniyani, Jhapa, Nepal from January to July 2021 manage the Yellow Stem Borer (YSB) rice an environmentally responsible manner. The followed Randomized Complete Block Design (RCBD) with three replications seven treatments using spring Chaite-2. used were spin...

The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is one of the most important pests that has developed high pesticide resistance. The resistances of five Chinese populations of this moth, four resistant strains (from Beijing, Henan, Fujian, and Guangdong) and one susceptible strain, to five pesticides were determined, and the activities of carboxylesterase, glutathione...

An assessment was made of the fumigant toxicity of 36 constituents from lemon balm oil (LBO) and summer savory oil (SSO) and another additional nine previously identiÞed compounds of the oils, as well as of the control efÞcacy of four experimental spray formulations containing individual oils (0.5 and 0.1% sprays) and spinosad 10% suspension concentrate (SC) to females from Band neonicotinoid-r...

Insecticide bioassays of the leafrollers, Choristoneura rosaceana (Harris), and Pandemis pyrusana Kearfott (Lepidoptera: Tortricidae), were used to investigate resistance and cross-resistance between azinphosmethyl and other insecticides. Comparisons of field-collected populations with susceptible laboratory colonies of both leafroller species were made in 1996-97, prior to registration and fie...

Pest management practices may be contributing to a decline in wild bee populations in or near canola (Brassica napus L.) agroecosystems. The objective of this study was to investigate the direct contact toxicity of five technical grade insecticides--imidacloprid, clothianidin, deltamethrin, spinosad, and novaluron--currently used, or with potential for use in canola integrated pest management o...

The model organism Streptomyces coelicolor A3(2) harbors a 356-kb linear plasmid, SCP1. We report here development of a recombinational cloning method for deleting large segment from one telomere of SCP1 followed by replacing with the telomere of pSLA2 and sequentially inserting with the overlapping cosmids in vivo. The procedure depends on homologous recombination coupled with cleavage at telo...
