Ischnura senegalensis, which widely spreads in paddy fields, has the potential to be used as a natural predator of insect pests. However, application insecticides field could pose threat survival I. senegalensis. Among these pesticides, indoxacarb, an oxadiazine insecticide, is renowned for its broad-spectrum efficacy against numerous In this study, we examined toxicity indoxacarb towards larvae Behavioral experiments and transcriptome analyses were conducted under treatments. Results revealed that induced abnormal body gestures significant locomotory impairments, ultimately reduce rate their habitat. Moreover, indicated genes related muscle function significantly affected. Interestingly, at lower concentrations (0.004 mg/L), seem detoxify with aid cytochrome P450 gene. higher (0.4 sensory abilities diminished, they unable degrade indoxacarb. Our study underscores importance carefully evaluating impact on non-target predatory insects before widespread application.

Matricaria chamomilla Essential Oils: Repellency and Toxicity against Imported Fire Ants (Hymenoptera: Formicidae)

Molecules, Journal Year: 2023, Volume and Issue: 28(14), P. 5584 - 5584

Published: July 22, 2023

Matricaria chamomilla flower essential oils (EOs) blue Egyptian (EO-1), chamomile German CO2 (EO-2), and (EO-3) the pure compound α-bisabolol were evaluated against red imported fire ants (RIFA), Solenopsis invicta Buren, black ants, S. richteri Forel (BIFA), hybrid (HIFA) for their repellency toxicity. A series of serial dilutions tested starting from 125 µg/g until failure treatment. Based on amount sand removed, EO-1 showed significant at dosages 7.8, 31.25 RIFA, BIFA, HIFA, respectively. EO-3 was repellent 3.9, whereas active DEET (N, N-diethyl-meta-toluamide) µg/g. Toxicity EOs mild to moderate. For EO-1, LC50 values 93.6 188.11 RIFA BIFA; 98.11 138.4 EO-2; 142.92 202.49 EO-3, The 159.23 RIFA. In conclusion, M. offer great potential be developed as ant repellents.

Museum Genomics of an Agricultural Super-Pest, the Colorado Potato Beetle, Leptinotarsa decemlineata (Chrysomelidae), Provides Evidence of Adaptation from Standing Variation

Integrative and Comparative Biology, Journal Year: 2022, Volume and Issue: 62(6), P. 1827 - 1837

Published: Aug. 24, 2022

Despite extensive research on agricultural pests, our knowledge about their evolutionary history is often limited. A mechanistic understanding of the demographic changes and modes adaptation remains an important goal, as it improves organismal responses to environmental change ability sustainably manage pest populations. Emerging genomic datasets now allow for characterization adaptive processes, but face limits when they are drawn from contemporary samples, especially in context strong change, repeated selection, or involving modest shifts allele frequency at many loci. Temporal sampling, however, can improve reconstruct events. Here, we leverage museum samples examine whether population diversity structure has changed over time, identify regions that appear be under selection. We focus Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say 1824; Coleoptera: Chrysomelidae), which widely regarded a super-pest due its rapid, repeated, evolution insecticides. By combining whole genome resequencing data 78 with modern demonstrate CPB expanded rapidly 19th century, leading reduction limited genetic Midwest Northeast United States. scans provide evidence selection acting resistant field populations Wisconsin New York, including numerous known insecticide resistance genes. also validate these results by showing selective sweeps identified scan. Perhaps most importantly, temporal analysis indicates standing variation, find parallel two geographical regions. Parallel involves range phenotypic traits not previously CPB, such reproductive morphological functional pathways might habitats.

The red imported fire ant, Solenopsis invicta Buren, is a severe pest with agricultural, ecological, and medical significance. baiting treatment one of the main methods to control S. invicta. However, few studies have evaluated acceptance ant bait. Here, field laboratory were conducted investigate foraging behaviors responding baits containing different concentrations active ingredients (fipronil, abamectin, or indoxacarb). Field showed that transported significantly less 0.0125% fipronil bait than (without toxicant) 0.0001% number ants decreased an increase in concentration. Our previous study usually buries food treated repellent chemicals, interestingly, more soil particles into tubes In addition, 0.0005% abamectin bait, fewer found there was no significant difference transport, ants, weight relocated indoxacarb (0.0025% 0.0125%) (0.0125% 0.0625%). transport speed for slowest.

Chemicals, including toxic bait and dusts, are the main means of controlling red imported fire ant Solenopsis invicta (abbreviation 'RIFA'), which is a serious invasive pest. To identify environmentally friendly chemicals for RIFA, we tested toxicity horizontal transfer three botanical insecticides-matrine, rotenone, pyrethrin-and their impact on aquatic organisms (i.e., fish one shrimp). The LD50 value matrine, pyrethrin was 0.24, 50.929, 13.590 ng/ant, respectively. Matrine, had effective caused significant secondary mortality. After exposure to donor workers, 90.75%, 100% recipient workers in 0.025% 1.0% 0.3% dust treatments, respectively, died within 48 h. Furthermore, matrine tertiary mortality (49.5%).
