Funding information National Institute of Food and Agriculture, Grant/Award Number: 2015-3438323710; USDA-NIFA: IR-4 Minor Pest Crop Management Program, Grant/Award Number: 2015-34383-23710 Abstract Drosophila suzukii Matsumura is a significant pest of softskinned fruit. Larvae of D. suzukii develop within the fruit making it unmarketable as fresh berries and increasing the risk of rejection by...

The introduction of an agricultural pest species into a new environment is a potential threat to agroecosystems of the invaded area. The phytosanitary concern is even greater if the introduced pest's phenotype expresses traits that will impair the management of that species. The invasive tomato borer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is one such species and the characterizati...

The mosquito Aedes aegypti is the primary vector of different arboviruses and represents a major public health problem. Several Brazilian populations of Ae. aegypti have developed resistance to temephos, the most used organophosphate larvicide. New tools which are less harmful to the environment and safer for humans are becoming increasingly important to control this insect vector. Spinosad, an...

Wedetermined that spinosad interacts synergistically with the biocontrol agentMetarhizium anisopliae (Metch) Sorokin to increase the mortality of two wild-collected wireworm species, Agriotes lineatus(L.), andAgriotes obscurus(L.).BioassayswereperformedusingaM.anisopliae isolate originally acquired from a local wireworm cadaver.M. anisopliaewas applied as a soil drench at 3.3 10 and 10 conidia ...

BACKGROUND This study was undertaken to identify the potential side effects of the novel naturalyte insecticide spinetoram in comparison with spinosad on the bumblebee Bombus terrestris L. The potential lethal effects together with the ecologically relevant sublethal effects on aspects of bumblebee reproduction and foraging behaviour were evaluated. Bumblebee workers were exposed via direct con...

METHODS An ectoparasiticide containing spinosad was evaluated as an oral formulation for cats. Two European laboratory studies and a European multicentre field efficacy and safety study assessed the use of a chewable tablet formulation of spinosad at a dose range of 50-75 mg/kg for treatment and control of flea infestations on cats. RESULTS The studies with experimentally infested cats consis...

The red palm weevil, Rhynchophorus ferrugineus, is of great concern worldwide, especially in the Middle East, where dates are a strategic crop. Despite their ecological hazard, insecticides remain the most effective means of control. A bioinsecticide of bacterial origin, spinosad is effective against several pests, and its efficacy against male R. ferrugineus was assessed in the present study. ...

Chlorpyrifos, lambda-cyhalothrin, cypermethrin, spinosad and buprofezin were tested against the second instar larvae and adults (except buprofezin) of the green lacewing, Chrysoperla carnea. The results showed that chlorpyrifos was more toxic to second instar larvae than lambda-cyhalothrin, cypermethrin, spinosad and buprofezin with LC50 values of 1.78, 8.81, 26.9, 294.36 and 997.05 ppm respect...

Dissolved oxygen (DO) is an important influencing factor in the process of aerobic microbial fermentation. Spinosad is an aerobic microbial-derived secondary metabolite. In our study, spinosad was used as an example to establish a DO strategy by multi-scale analysis, which included a reactor, cell and gene scales. We changed DO conditions that are related to the characteristics of cell metaboli...

The effectiveness of spinosad for larval mosquito control is summarized based on available published literature and some heretofore unpublished studies. Spinosad is highly active against larvae of all mosquito species tested thus far. It is effective at similar dosages for all larval mosquito instars, with peak cumulative mortality occurring at 72 h posttreatment. More studies are needed to ful...
