This study describes the chemical characterisation of two extracts (ethyl acetate, EtOAc-E and hexanic, Hx-E) from fruits and their insecticidal properties on . The HPLC analysis in EtOAct-E revealed the presence of ellagic acid and phenolic compounds. The CG-MS analysis in Hx-E revealed the presence of Hexadecanoic acid, 11-Methylheptacosane, Dodecanoic acid and Nonacosane as major compounds. The application of both extracts was performed on the dorsal part of each larva aspersion. The larval mortality, relative growth and emergence percentage of adults were evaluated. The Hx-E caused a 93.33% mortality at 100 mg/mL at 24 h post-application. A minor relative growth with both EtOAc-E (12.64 mg) and Hx-E (7.90 mg) was observed compared with their respective negative controls (methanol = 25.05 mg and tween20 = 24.53 mg). The lowest emergence percentage of adults with the Hx-E (25%) at 50 mg/mL was observed. fruits exhibit insecticidal properties against .

Environmental organic pollution causes a threat to the ecological environment, constrains social development and can also potentially harm human health. We applied non-target analysis to screen organic pollutants from the serum of 89 individuals, identifying 67 pollutants in the categories of industrial intermediates, plasticizers, surfactants, pharmaceuticals, pesticides, and exogenous pollutant metabolites. The detection rate of chemicals for industrial use (50.

The evolutionary arms race between plants and insects has led to key adaptive innovations that drive diversification. Alkaloids are well-documented anti-herbivory compounds in plant chemical defences, but how these specialized metabolites are allocated to cope with both biotic and abiotic stresses concomitantly is largely unknown. To examine how plants prioritize their metabolic resources responding to herbivory and cold, we integrated dietary toxicity bioassay in insects with co-expression analysis, hierarchical clustering, promoter assay, and protein-protein interaction in plants.

Pyrethroids are synthetic products derived from natural pyrethroids present in flowers and are extensively used as pesticides for agriculture, animal husbandry, and household pest control. However, excessive and prolonged usage of pyrethroid insecticides can result in adverse effects on both non-target and target species. Therefore, effective technologies need to be developed to remove pyrethroid contamination and ensure environmental safety.

Wheat is the third most widely consumed cereal in the world, after maize and rice. However, it is regularly attacked by the wheat aphid (), causing considerable damage to wheat crops. The acetylcholinesterase enzyme, which plays a key role in the transmission of the synaptic cholinergic signal, has emerged as a promising target for the development of pest control strategies.
