Synergistic avermectin combination. Dybas, Richard A. (Merck and Co., Inc. , USA). Eur. Pat. Appl. EP 94779 A1 23 Nov 1983, 32 pp. DESIGNATED STATES: R: AT, BE, CH, DE, FR, GB, IT, LI, LU, NL, SE. (English). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: A01N043-90; A01N025-02. APPLICATION: EP 83-302612 9 May 1983. PRIORITY: US 82-376362 10 May 1982. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) Avermectins I (R1 = H or II; R2 = H or OH ; R3 = sec-Bu or iso-Pro; R4 = H or Me; n = 0 or 1) in combination with an agricultural spray oil are synergistic pesticides suitable for control of the motile stages of arthropod pests. Thus, spray application of a mixt. of contg. avermectin B1a [65195-55-3] and avermectin B1b [65195-56-4] in combination with an agricultural spray oil (Sunspray 6N) (0.25%), at an avermectin concn. of 0.04 oz/100 gal, synergistically controlled citrus rust mites (Phyllocoptruta oleivora) on oranges and reduced percent russeting to 5%.

Pink bollworms (Lepidoptera: Gelechiidae): effects of low concentrations of selected insecticides on mating and fecundity in the laboratory

Pink bollworms (Lepidoptera: Gelechiidae): effects of low concentrations of selected insecticides on mating and fecundity in the laboratory. Bariola, Louis A. (Agric. Res. Serv., U.S. Dep. Agric., Phoenix, AZ 85040, USA). J. Econ. Entomol., 77(5), 1278-82 (English) 1984. CODEN: JEENAI. ISSN: 0022-0493. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Pink bollworm, Pectinophora gossypiella, moths treated with low doses of certain insecticides had a lower percentage of mating, laid fewer eggs, and, in some cases, had a reduced no. of eggs hatch. The synthetic pyrethroids cyfluthrin [68359-37-5], fenpropathrin [39515-41-8], fenvalerate [51630-58-1], flucythrinate [70124-77-5], and permethrin [52645-53-1] all caused redns. in mating during the 1st 24-h period after treatment. The insecticides also reduced the no. of eggs laid. Redns. in mating and oviposition caused by treatment with azinphosmethyl [86-50-0], methyl parathion [298-00-0], trichlorfon [52-68-6], carbaryl [63-25-2] and chlordimeform [6164-98-3] were usually assocd. with or were the result of high mortality. Avermectin B (MK-936) [65195-56-4], completely prevented mating and oviposition at the LD10 and LD50 with little mortality among the treated insects. Hatching of eggs was also reduced by these treatment levels of Avermectin B1. Thus, in addn. to causing mortality, treatments of moths with certain insecticides may cause population suppression through reduced mating, fecundity and hatching of eggs.
