2012, Studies in Natural Products ChemistryCitation Excerpt :Moreover, the two preparation containing avermectins MK-933 (368) and MK-936 (364 + 365) in addition to spinosad suspension (Tracer®, 369 + 372) presented LC50 values of 0.0234, 0.0104, and 0.025 ppm, respectively. Treatment of larvae with α-terthienyl (26) and the furanoacetylene (30) exhibited an exceptional phototoxic effect against fourth instar larvae and exceeded the effectiveness of DDT and malathion encouraging the indication of 26 to be a practical larvicide under field conditions [50]. Spinosad proved to be useful in integrated vector management programs targeted at Ae.
Acute and reproductive toxicity of Annona squamosa to Aedes albopictus
2011, Pesticide Biochemistry and PhysiologyCitation Excerpt :Pyrethrum from Chrysanthemum cinerariaefolium (Asteraceae) is one of the best-known natural insecticides and has provided a lead for the synthesis of various pyrethroid derivatives. Following the discovery of this phytotoxin, numerous studies have been conducted concerning the larvicidal properties of plants in general [9–18]. Compounds derived from plants of the family Annonaceae are known to exhibit toxic effects on wide range of organisms [19–28].
Photochemical and Photophysical Behavior of Thiophene
2011, Advances in Heterocyclic ChemistryCitation Excerpt :A 100% mortality was observed in the presence of 0.5 ppm of polythiophenes (81MI59; 82MI2565; 83MI377; 84BBA(802)442). On larvae of flies (Aedes aegypti), a concentration of 0.019 ppm of the polythiophene was sufficient to kill 50% of flies, while DDT gave a value of 0.070 ppm (81MI59; 81MI63; 92MI261; 94MI745). In the presence of UV irradiation, both inhibition of germination e growth in 5 cm plants of dicotyledonous (Asclepias siriaca) and herbicidal activity were observed (82MI961).
