Food security and safety are the major concern in ever expanding human population on the planet earth. Each and every year insect pests cause a serious damage in agricultural field that cost billions of dollars annually to farmers. The loss in term of productivity and high cost of chemical pesticides enhance the production cost. Irrespective use of chemical pesticides (such as Benzene hexachlor...

Organophosphates have been widely used as insecticides and chemical warfare agents. The health risks associated with these agents have necessitated the need for better detoxification and bioremediation tools. Bacterial enzymes capable of hydrolyzing the lethal organophosphate nerve agents are of special interest. Phosphotriesterase (PTE) isolated from the soil bacteria Pseudomonas diminuta disp...

Insect pathology has a long history dating back to the earliest studies in microbiology. A select few of the many known insect pathogens can be produced and used on an industrial scale as biopesticides and are championed for their low environmental impact. The commercial application of microbial insecticides has been limited competition with chemical insecticides. However, the advent of gene te...

Genetically modified baculoviruses offer a promising alternative to chemical insecticides in the control of agricultural and forest insect pests. A novel bacmid, HaBacYH6, was constructed in which the ecdysteroid UDP-glucosyltransferase gene (egt) was replaced with a bacterial replication cassette containing a mini-F replicon, a kanamycin resistance gene, and the attTn7 site. Insertion of the e...

The cotton bollworm Helicoverpa armigera occurs as a major pest in many economically important crops, including cotton, pigeon pea, chickpea, cowpea, sunflower, tomato, sorghum, pearl millet and other crops. Intestinal microorganisms play role the degradation of diet components insects. In order to know gut bacteria insecticide resistance five insecticides Chlorpyriphos (20% EC), Cypermethrin (...

volume is divided into two parts. Part one contains specifications for technical DDT, BHC, met oxyc or^ chlordane, dieldrin, BHC containing 90% or rnore isomer, Pyrethrem extract (cerosol grade), water dispersible powder concentrates containing DDT and BHC and emulsion concentrates containing DDT, BHC and Dieldrin, all being intended for use against vectors of diseases of man. Part two contains...

Abstract An organophosphorus (OP) insecticide-mineralizing strain, Lactobacillus plantarum WCP931, harboring a new OP hydrolase (opdC) gene, was isolated during kimchi (Korean traditional food) fermentation. Strain WCP931 exhibited significant survival rate of 51 to 96% under artificial gastric acid conditions at pH 2 3 after h. The opdC consisting 831 bp encoding 276 amino acids, cloned from s...

Significance The insect respiratory system consists of tubular tracheae that transport oxygen to the organs. We show that, in pest Riptortus pedestris , establishment an essential symbiosis gut with aerobic bacterial species Burkholderia insecticola triggers development extensive tracheal network enveloping gut. Genetically blocking trachea formation prevents this symbiosis. further discovered ...

The rising use of pesticides in modern agriculture has led to a shift disease burden which exposure these chemicals plays an increasingly important role. human gut microbiome, is partially responsible for the biotransformation xenobiotics, also known promote environmental pollutants. Understanding effects occupational pesticide on microbiome can thus provide valuable insights into mechanisms un...
