The toxicity of microplastics (MPs) has been demonstrated in several previous studies, exposing different model organisms to fluorescent-labeled particles. However, many these studies did not report the use control groups for unbound and leaching dyes, which limits conclusions about bioaccumulative potential micromaterials their (eco)toxicological effects. Thus, considering need evaluate possibility MPs resulting from we used Physalaemus cuvieri tadpoles investigate whether leachate...
Formamidines are unique insecticides and acaricides that elicit multiple effects in controlling insects. Here, we tested two formamidines, amitraz, chlordimeform, for their synergistic actions on type II pyrethroids neonicotinoids to increase larvicidal the fourth instars of Aedes aegypti L. An organophosphate insecticide was used as a negative control. After 24 h, synergism formamidines highest imidacloprid, followed by pyrethroids, deltamethrin fenvalerate. 48 imidacloprid decreased,...
This study aimed to employ GC-MS assess the chemical composition of MeOH leaf extracts R. officinalis and A. indica evaluate their insecticidal, antioxidant, antibacterial activities. Twelve components, representing 98.61% 100% total volatile compounds, were deduced from extracted indica, respectively, using this method. In extract, limonene is typically positioned as main component (23.03%), while chemicals identified in extract methyl (E)-octadec-13-enoate (23.20%)...
Synergistic effects of octopamine receptor agonists (OR agonists) have attracted many scientists based on their potent mosquitoes. Herein, we determined the toxicity selected insect growth regulators (IGRs) fourth instar larvae Culex quinquefasciatus. We evaluated synergistic action OR IGR insecticides to achieve a better understanding mode action. As result, pyriproxyfen was most insecticide (EC50 = 0.049 ng/ml) followed by lufenuron, novaluron, and diflubenzuron according bioassay....
Abstract The sand termite, Psammotermes hypostoma Desneux is a major pest in the New Valley Governorate, Egypt. Great efforts have been taken to control pest. We evaluated toxicity of four selected neonicotinoids [acetamiprid (20% SP), imidacloprid SL), thiamethoxam (18.6% SC), and (40% WG)], one organophosphate pesticide [chlorpyrifos (48% EC)] against P. workers. investigation was done under field conditions, using palm fronds method. However, reduction percentages recorded as height sandy...
The use of conventional pesticides becomes a complicated issue as more species insect pests become resistant to them. Nanopesticides suit new approaches in pest control. Herein, we tested the toxicological efficacy imidacloprid compared with three its nanoformulations (IMD01, IMD02, and IMD03) on second fourth instar Culex pipiens larvae. Furthermore, assessed synergistic actions piperonyl butoxide (PBO) against C. pipiens. nanoformulation (IMD03) was most potent insecticide (LC50 = 14, 6, 2...
Forensic entomology is considered the science that applies insect biology to criminal investigations, using insects and other arthropods uncover circumstances of cases.Herein, we recorded seasonal abundance forensic encountered on rabbits' cadavers during four seasons (2021)(2022) in Egypt under Assiut conditions.As a result, numerous were attracted (2021-2022).Plus, ten adult observed belonging seven families two orders, Coleoptera Diptera.Four coleopteran 4 monitored, "i.e." Carabidae...
The susceptibility of field and laboratory strains against all instars larvae S. littoralis to spinosad pesticide after a 24- 48-h exposure under conditions was investigated. As result 1st instar larvae, the LC50 values 24 h were 12 0.275 µg/ml for strain, respectively. In addition, resistance ratio (RR) 43.64-fold. this interim, 48 8.7 0.18 respectively RR 48.33-fold, which revealed strain more susceptible than strain. Distinctly similar trend shown later stages. For instance, in 6th 24-h...
