Biochemical Responses of Anopheles spp. Larvae to a Novel Brazilian BR101 Bacillus thuringiensis var. israelensis Formulation: Oxidative Stress, Detoxification Enzymes, and Safety for Nontarget Notonectidae and Gerridae Aquatic Insects. [PDF]

open access: yesChem Biodivers
Bti BR101 exhibits strong larvicidal activity against Anopheles larvae spp., with dose‐dependent mortality and LC50 of 3.13 µg/mL. Bti increases ROS, lipid and protein oxidation, and activates antioxidant enzymes (SOD, CAT, GPx) and detoxification pathways (MFO and esterases), indicating moderate oxidative stress.

Present and future potential of plant-derived products to control arthropods of veterinary and medical significance [PDF]

open access: yes, 2014
The use of synthetic pesticides and repellents to target pests of veterinary and medical significance is becoming increasingly problematic. One alternative approach employs the bioactive attributes of plant-derived products (PDPs). These are particularly
