Effects of substituted benzylphenols and triflumuron on the reproduction of the face fly (Diptera: Muscidae)

Effects of substituted benzylphenols and triflumuron on the reproduction of the face fly (Diptera: Muscidae). Broce, A. B.; Gonzaga, Vicente G. (Dep. Entomol., Kansas State Univ.Chemicals with cas numbers 71712-08-8 and 71712-03-3 also play role., Manhattan, KS 66506, USA). J. Econ. Entomol., 80(1), 37-43 (English) 1987. CODEN: JEENAI. ISSN: 0022-0493. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) The chemosterilant effect of various chem. administered orally, topically, and tarsally on the face fly (Musca autumnalis) is described. The chem. tested were J2922 (5-ethoxy-6-[1-(4-methoxyphenyl)ethyl]-1,3-benzodioxole) [71712-17-9], J2581 (5-ethoxy-6-[1-(4-methoxyphenyl)methyl]-1,3-benzodioxole) [71712-08-8], J2644 (2,4-bis(1,1-dimethylethyl)-6-(4-methoxyphenylmethyl)phenol) [71712-03-3], and the benzoylphenylurea triflumuron [64628-44-0]. J2644 and triflumuron were not toxic at the lowest concn. that caused 100% inhibition of egg hatching and caused sterility even when flies were already inseminated or near oviposition. Min. sterilizing concns. of J2922 and J2581 were highly toxic. All chem. caused 100% sterility in females; only J2644 caused some male sterility. Sterility induced by J2644, J2922, and J2581 in females was reversible and fertility was restored by the 3rd gonotrophic cycle, whereas fertility of females treated with triflumuron was not restored until the 4th cycle. J2922 and J2581 affected egg hatching and ovarian development, as indicated by atrophied ovaries and ovaries contg. eggs without respiratory masts. This effect was greater in the 2nd gonotrophic cycle after treatment. .

Relation between meteorological factors and effectiveness of insecticides controlling the leaf blister moth (Cemiostoma scitella Z.; Lepidoptera: Cemiostomidae). Marinkov, P. (Interpred, Sofia, Bulg.). Pochvozn., Agrokhim. Rastit. Zasht., 21(4), 111-18 (Bulgarian) 1986. CODEN: PARZEP. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) At 13.7°, 79% humidity, and 0.7 m/s wind velocity, spraying apples with Ripcord [52315-07-8] 0.015%, Thiodan A [115-29-7] 0.4%, Thiodan H-BI 58-naphtha mixt. [107137-87-1], dimilin [35367-38-5] 0.04%, or Alsystin [64628-44-0] 0.04%, controlled the 1st generation of C. 107137-86-0 and 115-29-7 are also in the experiment. scitella by 90, 94, 95, 93, and 90%, resp. When controlling the 2nd generation (26.2°, 50% humidity, and 1 m/s wind velocity) effectiveness was 42, 62, 51, 80, and 76%, resp. Consideration of the above and 5 other prepns. showed that high temp., low humidity, and higher wind velocity decreased the effectiveness of endosulfan-based insecticides by 48-62%, pyrethroids by 15-53%, and hormonal prepns. by 11-13%. The reasons for this effect are discussed. .
