Abstract The yellow fever mosquito, Aedes aegypti , particularly in Neotropical regions, is the principal vector of dengue, fever, Zika and Chikungunya viruses. Pyrethroids remain one most used insecticides to control mosquitoes, despite development pyrethroid resistance many mosquito populations worldwide. Here, we report a Brazilian strain A. with high levels (approximately 100–60,000 fold) both type I II pyrethroids. We detected two mutations (V410L F1534C) sodium channel from this...
Declines in pollinator colonies represent a worldwide concern. The widespread use of agricultural pesticides is recognized as potential cause these declines. Previous studies have examined the effects neonicotinoid insecticides such imidacloprid on colonies, but investigations mainly focused adult honey bees. Native stingless bees (Hymenoptera: Apidae: Meliponinae) are key pollinators neotropical areas and threatened with extinction due to deforestation pesticide use. Few directly...
The in vitro rearing of worker honey bees (Apis mellifera L.) has become an increasingly important method bee research general, and pesticide risk assessment specifically. Authorities from the European Organization for Economic Co-operation Development United States Environmental Protection Agency are requesting data on impacts immature survivorship prior to registering new crop protection products. Those using current protocols have had variable success with survival protocol repeatability....
In this study, a leaf extract from Schinus terebinthifolius was evaluated for effects on survival, development, and midgut of A. aegypti fourth instar larvae (L4), as well toxic effect Artemia salina. Leaf obtained using 0.15 M NaCl phytochemical composition lectin activity. Early L4 were incubated with the (0.3–1.35%, w/v) 8 days, in presence or absence food. Polymeric proanthocyanidins, hydrolysable tannins, heterosid aglycone flavonoids, cinnamic acid derivatives, traces steroids,...
Bee pollination is crucial for ecosystem maintenance and crop production. The ubiquity of bee pollinators in agricultural landscapes frequently results their exposure to agrochemicals, which has been associated with decline. Stingless bees are wild restricted the Pantropical region, like honey bees, suffering colony losses. However, stingless do not show same behaviors, therefore, methods used risk assessment cannot be utilized on bees. Herein, we describe protocols standardize that allow...
Manual monitoring of animal behavior is time-consuming and prone to bias. An alternative such limitations using computational resources in behavioral assessments, as tracking systems, facilitate accurate long-term evaluations. There a demand for robust software that addresses analysis heterogeneous environments (such field conditions) evaluates multiple individuals groups while maintaining their identities. The Ethoflow was developed computer vision artificial intelligence (AI) tools monitor...
As honeybees are the main pollinator subject to an intense research regarding effects of pesticides, other ecologically important native bee pollinators have received little attention in ecotoxicology and risk assessment pesticides general, insecticides particular, some which perceived as reduced-risk compounds. Here, impact three – azadirachtin, spinosad chlorantraniliprole was assessed two species stingless bees, Partamona helleri Scaptotrigona xanthotrica, Neotropical America. The...
Actinobacillus pleuropneumoniae is responsible for swine pleuropneumonia, a respiratory disease that causes significant global economic loss. Its virulence depends on many factors, such as capsular polysaccharides, RTX toxins and iron-acquisition systems. Analysis of may require easy-to-use models approximate mammalian infection avoid ethical issues. Here, we investigate the potential use wax moth Galleria mellonella an informative model A. infection. Genotypically distinct clinical isolates...
The yellow fever mosquito Aedes aegypti is essentially a container-inhabiting species that closely associated with urban areas. This vector of human pathogens, including dengue and viruses, its control paramount importance for disease prevention. Insecticide use against juvenile stages (i.e. larvae pupae) growing in importance, particularly due to the ever-growing problems resistance adult-targeted insecticides safety concerns regarding such dwellings. However, insecticide effects on insects...
The global decline in Apis mellifera colonies is attributed to multiple factors, including pesticides. bioinsecticide spinosad was initially recognized as safe for non-target organisms; however, its toxicity has been changing this view. Here, we investigated the survival, behavioral changes, and structural changes midgut Malpighian tubules of A. treated orally with a formulation.The field-recommended concentration killed 100% bees. 5% 50% lethal concentrations (LC5 LC50 , respectively)...
Juvenile hormone analogs (JHA) are known to interfere with growth and biosynthesis of insects potential for insecticide action. However, there has been comparatively few data on morphological effects JHA insect organs. To determine pyriproxyfen Aedes aegypti larvae, we conducted toxicity, behavioral bioassays assessed ultrastructural midgut cells. A. larvae were exposed in aqueous solution LC50 concentrations evaluated 24 h. This study fulfilled the toxic prevalence (LC50 = 8.2 mg L-1)....
Large-scale pesticide application poses a major threat to bee biodiversity by causing decline in populations that, turn, compromises ecosystem maintenance and agricultural productivity. Biopesticides are considered an alternative synthetic pesticides with focus on reducing potential detrimental effects beneficial organisms such as bees. The production of healthy queen stingless bees is essential for the survival reproduction hives, although it remains unknown whether biopesticides influence...
The lack of consensus regarding pollinator decline in various parts the planet has generated intense debates different spheres. Consequently, much research attempted to identify leading causes this decline, and a multifactorial synergism (i.e., stressors acting together mutually potentiating harmful effects) seems be emerging explaining phenomenon. emphasis on some stressor groups such as agrochemicals, pollinators honey bee Apis mellifera , can hide real risk anthropogenic pollinating...
