Synthesis of N-(1H -benzimidazol-2-yl)-6-substituted-1,3-benzothiazol-2-amines and 6-substituted-N-(4,5-dihydro-1H-imidazol-2-yl)-1,3-benzothiazol-2-amines by the reaction of substituted 2-aminobenzothiazoles with carbon disulphide and methyl iodide followed by the reaction with o-phenylene diamine/ethylene diamine are reported. All the synthesized compounds were characterized by elemental analysis, IR spectra and 1 H NMR spectral studies. The potent antibacterial and entomological (antifeedant, acaricidal, contact toxicity and stomach toxicity) activities of the synthesized compounds were investigated.

“…Second treatment (i8.iv.7O) Various authors have compared the activities of methoxy-DDT and DDT against mosquitoes. Ludvick (1953) found technical methoxy-DDT approximately 0-6 times as toxic as p,p'DDT to adult Anopheles quadrimaculatus Say by topical application. He considered that the difference would have been less if p,p'methoxy-DDT had been used.…”

The effects of residual sprays of methoxy-DDT wettable powder at 2 g/m2 on the mortality and behaviour of Anopheles gambiae Giles, Mansonia uniformis (Theo.) and Culex pipiens fatigans Wied. females were investigated in four verandah-trap huts, one of which was used as control. The overall mortality of no species ever exceeded 29%, and no consistent deterrent effect on entry was demonstrated. The proportions of mosquitoes in the exit traps were, for A. gambiae 80–90% in treated huts and 29–70% in the control, for M. uniformis 90–100% in treated and control huts, and for C. p. fatigans 26–84% in treated huts and 38–66% in the control. There were more unfed mosquitoes of all three species in the treated huts than in the control, for A. gambiae 35–64% and 10–53%, respectively, for M. uniformis 38–84% and 35–64%, respectively, and for C. p. fatigans 22–58% and 21–43%, respectively. Bioassays with wild-caught A. gambiae exposed to the treated surfaces for one hour, showed that the deposits remained highly toxic for 16 weeks on grass, six weeks on iron and two weeks, or less, on mud.

“…A literature search performed in Web of Science using a combination of the search words: “adult*,” “freshwater OR aquatic,” “insect*” and “pesticide* OR insecticide*” revealed that existing studies addressing insecticide exposure of adult freshwater insects generally focus on eradicating mosquitoes (Diptera, Culicidae) acting as vectors for human diseases (e.g. Georghiou & Metcalf, ; Ludvik, ; Schleier & Peterson, ). A limited number of studies report on insecticide usage aiming to control nuisance swarms of Trichoptera (especially the genus Hydropsyche ) disturbing human every‐day life, but do not present actual ecotoxicity data (e.g.…”

Insecticides are important drivers of biodiversity loss and ecological impairment in freshwater ecosystems. Freshwater insects may be exposed to insecticides via water during larval/nymph stages and via air, habitats, and food during adult stages in the terrestrial environment. The aquatic risk assessment (RA) of pesticides does not consider terrestrial life stages, and a literature review revealed that pesticide ecotoxicity data for adult freshwater insects are very scarce and outdated. Consequently, it is not possible to assess how adult freshwater insects may be protected through RA programs for terrestrial non‐target organisms. We give guidance to generating and using of such ecotoxicity data focusing on species selection, test design and type of ecotoxicity information. Policy implications. This commentary considers how terrestrial stages of aquatic insects are protected by pesticide risk assessment (RA) and highlights the necessity of performing holistic risk assessment, focusing on organisms and populations as supplement to current subdivisions in element‐based compartments (e.g. aquatic and terrestrial ecosystems).
