Summary: This study investigated the effects of sublethal doses of two neonicotinoid insecticides, acetamiprid and dinotefuran, on Chrysopa pallens. The results showed that these insecticides prolonged the development stages and preoviposition periods of the insects, but had no significant effect on their longevity and reproductive parameters. These findings provide important insights for the rational use of neonicotinoid insecticides and the protection of Chrysopa pallens.

Summary: This study analyzed the expression and functions of four insulin-like peptides in female adults of the natural predator Chrysopa pallens. The findings suggest that these peptides are involved in reproductive signaling at different degrees.

Summary: This study examined the anatomy and fine structure of the reproductive system of C. pallens. The male reproductive system consists of testes, vas deferens, seminal vesicles, accessory glands, and ejaculatory ducts. The spermatogenesis process includes the development of axoneme, nucleus, and enveloping materials in the spermatids. The accessory gland is composed of six parts and contains muscle fibers and secretory granules.

Summary: A diagnostic kit based on the glass vial bioassay has been developed for the rapid detection of resistance to various insecticides in Aphis gossypii. This diagnostic tool can quickly and accurately determine effective insecticides, making it significant for pest control and insecticide resistance management.

Summary: This study found that afidopyropen exhibits high acute toxicity to cotton aphids. Sublethal concentrations of afidopyropen significantly decrease adult lifespan, fecundity, and oviposition days, as well as prolong the developmental and reproductive periods of the progeny. Additionally, the population parameters of the progeny, such as net reproductive rate, intrinsic rate of increase, and finite rate of increase, are significantly reduced by exposure to sublethal concentrations of afidopyropen.

Summary: The study aimed to investigate the host specificity of the cotton-melon aphid and whether bacterial symbionts control the host specificity. The results showed that the host specificity of the cotton-melon aphid is not controlled by specific bacterial symbionts or by Buchnera abundance.

Summary: The resistance of cotton aphids to afidopyropen has been increasing in the major cotton-producing regions of China, posing a serious threat to cotton production safety. It is necessary to rotate or mix afidopyropen with other insecticides to inhibit the development of resistance.

Summary: This study assessed the impact of basil on aphid biological control by predatory lacewings, revealing that basil enhanced lacewings' longevity and fecundity, and modulated their colonization patterns. High density intercrop basil arrangements led to increased lacewing colonization rates, longer population persistence, and faster aphid decline, highlighting the potential of functional plants in enhancing pest control in agricultural systems.

Summary: The complete mitochondrial genome of Aphis gossypii Glover cucumber biotype was sequenced, revealing a genome length of 15,870 bp with 37 typical mitochondrial genes. The base composition of the genome is mainly A, T, C, and G, with varying percentages. Analysis identified multiple single nucleotide polymorphisms and an insertion and deletion in two A. gossypii biotypes' mitogenomes.

Summary: Afidopyropen is an effective novel insecticide with high toxicity to adult Aphis gossypii, with LC50 values ranging widely. Cotton plant-collected A. gossypii showed higher tolerance to Afidopyropen, indicating potential resistance development in the future.

Summary: Cotton is a key industrial crop in China, but the resistance of cotton aphids to pesticides poses a serious threat. Cyproflanilide has demonstrated effectiveness against cotton aphids, and its baseline susceptibility in field populations was determined. Field populations of cotton aphids were collected from major cotton-producing regions in China in 2021, and their susceptibilities to cyproflanilide were tested. The results showed that cyproflanilide was highly toxic to all populations of cotton aphids, while they exhibited high resistance to imidacloprid. Cyproflanilide is therefore a useful tool for monitoring and managing resistance in cotton aphids.

Summary: The study revealed that the cyantraniliprole-resistant strain CyR developed significant resistance through increased gene expression and cytochrome P450 activity compared to the susceptible strain SS, suggesting the involvement of multiple metabolic factors in the development of resistance.

Summary: This study found that the combination of certain insecticides with the entomopathogenic fungus Metarhizium anisopliae was more effective in controlling the cotton aphid than individual treatments. The toxicity of the insecticides was consistent with their compatibility with the fungus, with the combination of flonicamid and M. anisopliae showing the highest mortality rate.

Summary: In-depth research on chemosensory proteins (CSPs) revealed that CSPs play a crucial role in cotton aphids' resistance to pesticides. Functional verification of CSP1 and CSP4 in vivo and in vitro demonstrated that silencing CSPs through RNA interference significantly increased the sensitivity of resistant strains to corresponding pesticides. Transgenic Drosophila expressing CSPs exhibited varying tolerance mechanisms for different pesticides, indicating a potential role of overexpressed CSPs beyond pesticide resistance.
