Summary: The Colorado potato beetle is a major pest of potato plants with a rapid resistance development ability, leading to control failures with chemical insecticides. This study evaluated the combined use of insecticides and entomopathogenic nematodes for integrated control, showing increased efficacy against resistant populations. Further research on the use of synergistic chemicals with entomopathogenic nematodes is recommended for both laboratory and field conditions.

Summary: Based on degree-day phenology models, simulations showed distinct windows of opportunity for management programs, with some windows where insecticide applications only have a minor effect on population growth. The research also revealed that intergenerational effects greatly impact the optimal timings for subsequent generations.

Summary: A new generation amide insecticide residues analysis method has been developed using multiwalled carbon nanotubes (MWCNs) cleanup, QuEChERS, and ultrahigh performance liquid chromatography tandem mass spectrometry. The method has been successfully applied in complex matrices such as orange, celery, and onion, showing fine performance and effective reduction of matrix interference.

Summary: A photonic sensor based on inversed opal molecular imprinted polymer (MIP) film was developed to detect chlorantraniliprole (CHL) residue in tomatoes. The sensor displayed shifts in reflection spectra when incubated in CHL concentrations between 0.5 and 10 μg L-1, with stable values reached after about 30 minutes. This promising technology could be used as an economical and field-deployable screening tool for detecting CHL in crops.

Summary: Pesticides applied on agricultural land can impact aquatic ecosystems through runoff or leaching, with the study showing varying effects on aquatic plants and mayfly larvae. Different herbicides and insecticides showed different levels of toxicity towards the tested aquatic organisms, with potential latent effects observed in the study.

Summary: This study analyzed the sublethal exposure of the bioinsecticide spinetoram to Aedes aegypti larvae and its effects on adult performance and susceptibility to dengue virus infection. The surviving adult mosquitoes exhibited smaller size and weaker blood-feeding capacity, as well as transgenerational sublethal effects on offspring survival rates. Additionally, surviving adult females had higher viral loads of dengue virus after spinetoram exposure. Mechanistically, inhibition of oxidative phosphorylation may stimulate dengue virus production in adult Ae. aegypti.

Summary: This study explores the potential phosphorylation modification regulation mechanisms in Chilo suppressalis in response to sublethal chlorantraniliprole exposure using comparative and quantitative phosphoproteomics. The results reveal significant changes in the transcription and phosphorylation levels of genes/proteins associated with carbohydrate and lipid metabolism, cytoskeleton, signal transduction, transcription, translation, and post-translational modification in C. suppressalis due to sublethal chlorantraniliprole exposure. The identified protein kinases, including MAPKs, CDKs, CaMK II, PKA, PKC, and CK II, may play a direct role in the phosphoproteomics response of C. suppressalis to chlorantraniliprole treatment.

Summary: Hibernation is a short-term survival strategy for ectotherms to deal with cold weather and lack of food. This study examined the changes in endocrine hormones in the hypothalamus-pituitary-gonad axis of female lizards after exposure to chlorantraniliprole insecticide during hibernation. The results showed that the levels of several hormones were altered, indicating possible endocrine disrupting effects.

Summary: This study developed a modified method for detecting and quantifying pesticide residues in Moringa leaves and found an effective washing method to reduce these residues. Moringa is a promising crop for addressing nutritional security and has export potential. The study aims to improve crop management practices and suggest measures to reduce residue loads, benefiting researchers and policymakers.

Summary: This study comprehensively investigated the toxic mechanisms of chlorantraniliprole in fall armyworm through bioassay, transcriptomic, and biochemical analyses, revealing significant gene expression changes and altered metabolic pathways and enzyme activities, especially at the LC30 concentration. The findings provide insights into the adaptation and detoxification mechanisms in response to chlorantraniliprole exposure at a molecular level for fall armyworm and other insect pests.

Summary: Glyphosate, the active ingredient in Roundup(R) brand herbicides, has been tested for residues in food and the majority of residues are below safety standards, not due to agricultural practices or GM crop usage. regulatory agency surveys indicate that 99% of glyphosate residues in food are below the European MRLs or EPA tolerances.

Summary: This study investigated the adverse effects of sublethal chlorantraniliprole (CAP) exposure on Bombyx mori. Results showed that CAP induced intracellular Ca2+ release in BmN cells and caused mitochondrial dysfunction, autophagy, and apoptosis in the midgut of B. mori.

Summary: This study aims to evaluate the levels of small noncoding RNAs in the Colorado potato beetle under different temperature and insecticide treatments. The expression levels of genes associated with small noncoding RNA production or function were measured using qRT-PCR and showed selective modulation in response to temperature challenges and select insecticides. Additionally, RNAi-mediated reduction of a specific gene transcript was conducted, resulting in changes in survival rates for the insects exposed to different temperature conditions.
