Summary: This study used morphological tools to investigate the effects of pyriproxyfen on the midgut and fat body of the predator Ceraeochrysa claveri. The results showed that chronic exposure to pyriproxyfen led to increased development time, mortality, and histopathological alterations in both organs. The exposure also induced oxidative stress and cytoprotective responses. This study demonstrates the applicability and sensitivity of morphological analysis for evaluating the effects of insecticides on non-target organisms.

Summary: This article summarizes the use of insect cell lines in pest management and introduces several recent studies based on insect cell lines. These cell-based studies can increase efficiency and reduce the cost of insecticide research, providing a global and in-depth perspective to reveal and verify the mode of action of insecticides.

Summary: Chordotonal organs, miniature sensory organs in insects, rely on transient receptor potential (TRP) channels for their function. Among these channels, transient receptor potential vanilloid (TRPV) channels have been identified as targets for insecticides. By binding with TRPV channels, insecticides disrupt the normal function of chordotonal organs, leading to the elimination of pests. This review discusses the structure, types, and genetic relationships of TRPV channels in different species, highlighting their potential as targets for new highly efficient insecticides.

Summary: New neuroactive insecticides are discovered/registered differently, with lower value in use compared to neuroactive pharmaceuticals, but show clear similarities in their biochemical modes of action. This paper examines recent trends in pharmaceutical science and identifies technologies that may represent complementary approaches to insecticide discovery and mode of action determination.

Summary: Mosquitoes act as vectors for various diseases and parasites, and plant compounds are considered advantageous for controlling mosquito populations due to their target specificity and biodegradability. This review critically analyzes plant chemicals with larvicidal efficacy against mosquitoes and discusses their mode of action.

Summary: Sulfoximines, represented by sulfoxaflor, are a relatively new class of insecticides that exhibit distinct interactions with metabolic enzymes and nicotinic acetylcholine receptors, resulting in minimal cross-resistance compared to other insecticides. Some insect strains show resistance to neonicotinoids but little to no cross-resistance to sulfoxaflor. In laboratory studies, high levels of resistance to sulfoxaflor have been observed, possibly linked to enhanced metabolism by specific cytochrome P450s.

Summary: Pesticide resistance causes significant economic losses globally each year. Previous research has mainly focused on investigating the interactions between resistant pests and associated microbes, with a lack of quantification on the individual contributions of the pest host and associated microbes to resistance. This study compares resistant and sensitive strains and uses metaproteomics to analyze protein profiles, revealing contributions by the pest and its gut bacteria to phoxim resistance.

Summary: The lack of field-realistic experiments has limited our understanding of the risks of pesticides to natural insect populations, but an outdoor experiment revealed significant negative effects of commonly used insecticides on aquatic insect abundance and diversity. These findings emphasize the urgency of protecting freshwater insects and their surrounding ecosystems.

Summary: This study compared the population balance between insect pests and natural enemies under different treatment conditions in rice fields in Cambodia. The results showed that the use of biopesticides and orange oil extract could decrease insect pest populations without much affecting natural enemy populations, resulting in a more favorable balance. In one trial, the treatment with Beauveria bassiana (Bb) resulted in the highest grain yield while reducing insect pest populations. This indicates that the use of biopesticides in rice paddies is effective in maintaining a balanced population between insect pests and natural enemies, thereby reducing the impact on rice grain yields.

Summary: Termite symbionts have various benefits for their hosts, including increased fitness, nutritional supplementation, pathogen protection, and proper development. Recent studies have also found a link between bacterial symbionts and reduced effectiveness of insecticides, which has implications for pest control and bioremediation efforts. This study demonstrates that insect hosts can harbor symbionts with inherent insecticide tolerance, highlighting the potential for symbiont-mediated pesticide tolerance in termites.

Summary: Insect pollinators are often exposed to complex mixtures of pesticides. Traditional risk assessment methods based on single substances may underestimate the combined toxicity. In this study, the simultaneous exposure of honey bees to thiamethoxam and flusilazole demonstrated a synergistic effect with higher toxicity for thiamethoxam. The activities of various enzymes and the expression of genes associated with oxidative stress, immune response, lifespan, cell apoptosis, and detoxification metabolism were significantly altered. These findings highlight the importance of investigating the combined toxicity of pesticides and its potential contribution to the decline of bee populations.
