Pesticide residues contributing to the contamination of soil may influence microbial population of the soil and in turn fertility of soil. The present paper reports the effect of pesticides applied to soybean i.e. phorate, carbofuran, carbosulfan, thiomethoxam, imidacloprid, chlorpyriphos and monocrotophos on soil microflora. The viable count of rhizobia and phosphate solubilizing bacteria from...

The cotton aphid, Aphis gossypii Glover (Hemiptera Aphididae), is one of the most important sap sucking pests in many cotton-growing areas world-wide. In this study, the efficacies of seven insecticides [organophosphate (Fenitrothion & Pirimiphos-methyl), carbamate (Carbosulfan & Aldicarb), pyrethroid (Lambda-Cyhalothrin & Deltamethrin) and imidaclopride (Confidor)] were determined against four...

The use of synthetic acaricides for management of pest mites may alter the efficacy of the ectoparasitoid Tamarixia radiata (Waterston) in biological control of Diaphorina citri Kuwayama, the vector of the bacteria associated with huanglongbing (HLB) in citrus orchards. We evaluated the toxicity of 16 acaricides that are recommended for the control of citrus-pest mites to T. radiata. Acrinathri...

The tobacco whitefly Bemisia tabaci is one of the most devastating pests worldwide. Current management of B. tabaci relies upon the frequent applications of insecticides. In addition to direct mortality by typical acute toxicity (lethal effect), insecticides may also impair various key biological traits of the exposed insects through physiological and behavioral sublethal effects. Identifying a...

A study was conducted at the Eco-toxicology laboratory in the Department of Agricultural Entomology, University of Agriculture Faisalabad, against three species Apis florea, A. dorsata and A. mellifera of honey bees, to check long-term surviv...

A field survey in the farmers’ fields at Gurugram Haryana, few blocks focused on incidence of pests cabbage and cauliflower during rabi, 2017-18 2018-19. These revealed occurrence Plutella xylostella Spodoptera litura. Maximum number larvae P. S. litura was recorded Pataudi block as compared to those Farukhnagar, Sohana Gurugram. Seven neem-based biopesticides were evaluated along with check ca...

Farmed and wild samples of two weight Cirrhinus viz., 501-900 g and 901-1300 g of Cirrhinus mrigala were collected from a Commercial Fish Farm and from river Chenab at Trimu Head Jhang, respectively. The extracted residues were pesticides analyzed through reverse phase high performance liquid chromatography (HPLC) technique. Endosulfan α, p, p’-DDT, methamidophos, carbofuran, diazinon, parathio...
