Investigating zeta‐cypermethrin resistance stability in California Drosophila suzukii populations
After continuous selection and removal of selection pressure in spotted‐wing Drosophila, zeta‐cypermethrin resistance remained stable over several generations. Following a population bottleneck, zeta‐cypermethrin resistance increased without selection, highlighting the importance of insecticide rotation.

Identification of a mutation in the para-sodium channel gene of the cattle tick Rhipicephalus (Boophilus) microplus associated with resistance to synthetic pyrethroid acaricides [PDF]
Resistance against synthetic pyrethroid (SP) products for the control of cattle ticks in Australia was detected in the field in 1984, within a very short time of commercial introduction.

Plastic films for polytunnels can prolong the effective residual life of cypermethrin to over 6 months [PDF]
Synthetic pyrethroid insecticides are degraded almost entirely by ultraviolet (UV)-catalysed oxidation. A bioassay using the beetle Tribolium confusum duVal caged on bandages soaked in 0.04% a.i.

We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...

Effects of selected insecticides on osmotically treated entomopathogenic nematodes [PDF]
Combining environmentally friendly insecticides with entomopathogenic nematodes may constitute an effective alternative to conventional chemical control of many insect pests.

ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

ABSTRACT Since the late 1990s, the pesticide industry has undergone a ‘generics revolution’ as the centre of production, and trade has shifted to the global South. China and India have become major producers, capturing Latin American markets from Northern multinationals. As a major pesticide user and a key node in global supply chains, Argentina offers

Bioavailability of pesticides in freshwater sediments [PDF]
In ecological risk assessment standardized sediment toxicity tests are used to predict the hazard of chemicals for sediment-living organisms. Feeding is a prerequisite in these long-term tests to avoid starvation of test organisms.

A risk classification of registered pesticides in Brazil was conducted, and the contribution of food to cumulative pesticide exposure was evaluated. Model diets were proposed, based on Brazilian consumption patterns. Abstract BACKGROUND Pesticide residue exposure assessments can be carried out during both the pre‐regulation and post‐regulation phases ...

Environmental stress upon hepatopancreatic cells of freshwater prawns (Decapoda: Caridea) from the floodplain of Paraná River [PDF]
In order to evaluate the influence of stressed environments on hepatopancreatic cells of freshwater prawns, Macrobachium borellii Nobili, 1896 and Palaemonetes argentinus Nobili 1901, (Crustacea, Decapoda, Palaemonidae) were collected at three different ...
