Toxicity and kinetics of spinosad in different developmental stages of the endoparasitic wasp Hyposoter didymator (Hymenoptera: Ichneumonidae) and its host Spodoptera littoralis larvae (Lepidoptera: Noctuidae) Universiteit Gent
The toxicity of spinosad was evaluated using the RaPID Assay (R) Spinosad immunosorbent assay in different developmental stages of the parasitoid, Hyposoter didymator, and in its host, fourth-instar larvae of the cotton leafworm Spodoptera littoralis. Spinosad was applied directly to pupae and adults of H. didymator (ingestion or topical application) or to the immature stages of the parasitoid via the host larvae. Low amounts of spinosad were ...
The independent biological activity of Bacillus thuringiensis Cry23Aa protein against Cylas puncticollis Universiteit Gent
The Cry23Aa/Cry37Aa proteins fromBacillus thuringiensis(Bt) have been described toxic toCylas puncticollislarvae. In general, it is believed that Cry23Aa and Cry37Aa act jointly to exert the insecticidal activity, while there is no evidence of their toxicity individually. Therefore, in the present study, the contribution of each protein in the insecticidal activity towardC. puncticollislarvae has been assessed. The results showed that both ...
How a Scorpion Toxin Selectively Captures a Prey Sodium Channel: The Molecular and Evolutionary Basis Uncovered KU Leuven
The growing resistance of insects to chemical pesticides is reducing the effectiveness of conventional methods for pest control and thus, the development of novel insecticidal agents is imperative. Scorpion toxins specific for insect voltage-gated sodium channels (Navs) have been considered as one of the most promising insecticide alternatives due to their host specificity, rapidly evoked toxicity, biodegradability, and the lack of resistance. ...
Toxicity of erythritol, a sugar alcohol and food additive, to Drosophila suzukii (Matsumara) KU Leuven
Since its recent invasion in Europe (2008) Drosophila suzukii has been responsible for severe economic losses in small fruit, cherry and strawberry cultivation. Because of the short generation time and high fecondity it is likely that D. suzukii will become resistant to some of the most widely used pesticides like spinosad and lambda-cyhalothrin. The use of these toxic insecticides comes with health and safety issues for consumer and grower. ...
Malaria profiles and challenges in artemisinin resistance containment in Myanmar Instituut voor Tropische Geneeskunde
BACKGROUND: This study examined evolving malaria profiles from January, 2010 to December, 2014 to evaluate achievements and challenges of implementing measures to prevent and control spread of artemisinin resistance in Myanmar.
METHODS: Using National Malaria Control Programme (NMCP) data, a cross-sectional descriptive study of 52 townships in artemisinin-resistant containment areas in Myanmar was conducted. Annual program data were ...
