Article Abstract

A novel dispersive solid-phase microextraction method based on a metal-organic framework (MIL-100(Fe)) combined with a dispersive liquid-liquid microextraction technique was proposed for the extraction and enrichment of four insecticides in beverages. The qualitative and quantitative analysis of these insecticides was conducted using HPLC-MS/MS. To optimize the extraction process, several parameters were investigated, and the main variables were optimized using CCD-based RSM. The developed method displayed a wide linear range of 1.000-1000 ng/L and R values >0.993 for all four calibration curves. The method demonstrated high sensitivity, with LODs and LOQs of 0.3-0.6 ng/L and 0.8-1.0 ng/L, respectively. In addition, the greenness of the proposed method was assessed using the Complex GAPI tool, and the results showed that the proposed method exhibits benefits, such as minimal usage of organic solvents and negligible matrix influence, making it a suitable method for the detection of insecticide residues in beverages.

Background: Bacillus thuringiensis Cry toxins are well known for their insecticidal properties, primarily through the formation of ion-leakage pores via α4-α5 hairpins. His178 in helix 4 of the Cry4Aa mosquito-active toxin has been suggested to play a crucial role in its biotoxicity.

Objective: This study aimed to investigate the functional importance of Cry4Aa-His178 through experimental and computational analyses.

The olfactory system of insects plays a vital role in their survival by enabling them to detect chemical cues and adapt to changing environments. The rape stem weevil, Ceutorhynchus asper, is a significant pest posing a challenge for rapeseed production due to its destructive feeding habit and increasing resistance to insecticides. So far, there's still limited knowledge about structure and function of odorant binding proteins (OBPs) in beetles like C.

The cerambycid beetles are important components in the terrestrial ecosystem as they play a dual role in both degrading dying trees and killing healthy plants. The factors including human activity, habitat contraction, climate changes and pesticide use have been shaping the adaptation of beetles to host plants and the environment. As suggested in research on the functions of beetles' olfactory proteins, odorant binding proteins (OBPs) have been found to be involved in insecticide resistance other than chemoreception.

Splicing factor Nova regulates the splice variants in exons 3 and 6 of GABA receptor subunit RDL from Chilo suppressalis Walker (Lepidoptera: Crambidae).

The insect ionotropic γ-aminobutyric acid (GABA) receptor is an important insecticide target, and alternative splicing (AS) among exons 3a, 3b, 6a, and 6b of its RDL subunit is ubiquitous in insects; however, the AS factors and mechanisms remain unclear. While the neuro-oncological ventral antigen (Nova) is known to regulate AS of the γ2 subunit of mammalian GABA receptors, its role in insects remains unexplored. Two CsNova isoforms, CsNova-X1 and CsNova-X3, were identified by BLAST in the third-generation transcriptome of Chilo suppressalis.

Entomopathogenic fungi such as Metarhizium acridum are pivotal for sustainable pest management, yet the industrial conidial production is hindered by low yields and environmental sensitivity. Transcriptional regulation provides key targets for engineering strain modification. AP-1 transcription factors (TFs) are well-known for their roles in fungal growth, development, conidiation, pathogenicity and stress tolerance across various fungi.
