Effect of some ecological factors on the dynamics of the acquisition and transfer of resistance to insecticides in the Colorado beetle

Effect of some ecological factors on the dynamics of the acquisition and transfer of resistance to insecticides in the Colorado beetle. Lakocy, Antoni (Inst. Plant Prot., Poznan, Pol.). Dokl. Soobshch. - Mezhdunar. Kongr. Zashch. Rast., 8th, Volume 3, Issue 1, 377-86. Orgkom. VIII Mezhdunar. Kongr. Zashch. Rast.: Moscow, USSR. (Russian) 1975. CODEN: 37MVAB. DOCUMENT TYPE: Conference CA Section: 5 (Agrochemicals) Wintering Colorado beetles in Poznan District, Poland, were more resistant to Tritox (I-II-III) in areas with warmer climate and light soils than in cooler areas with clay soils. The beetles were more resistant to Azoto (I) [50-29-3] in river valleys than on ridges, and more in southern valleys with warmer climate than in northern valleys. The resistance to lindane (III) [58-89-9] developed at a slower rate than that to I. The acquired resistance to I-II-III had a higher degree of correlation with crossresistance to organophosphorus insecticides Sapecron [470-90-6], Ultracid [950-37-8], Valexon [14816-18-3], Evalux [66369-04-8], and Gusathion [86-50-0] than did the acquired resistance to I. The crossresistance to carbamates Unden [114-26-1], Padan [15263-52-2], and Elecron [6988-21-2] was equally strongly correlated with acquired resistance to I and I-II-III. In spite of replacement of I by carbaryl [63-25-2] the resistance of the beetles to I increased 10-fold within 2 yr. The resistance to III also continued to increase rapidly. The increasing resistance to I and III entailed a continued increase in crossresistance to organophosphorus and carbamate insecticides.

Studies on substitute pesticides for prevention and extermination of insects. Wei, Hung-Chun; Chang, Chih-Ti (Peop. R. China). Chung-Kuo Nung Yeh K'o Hsueh, (3), 67-71 (Chinese) 1977. CODEN: CKNYAR. ISSN: 0578-1752. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) The thiophosphate Phoxim [14816-18-3] gave excellent control of Gryllotalpa unispina, Holotrichia oblita, Anomala corpwlenta, but this organophosphate compd. was relatively nontoxic to mammals as compared to other pesticides. Diazinon [333-41-5], padan [15263-52-2], permethrin [52645-53-1], and other organophosphates were also effective in controlling these organisms.
