Persistence of insect growth regulators against the rice weevil, Sitophilus oryzae, in grain commodities

Persistence of insect growth regulators against the rice weevil, Sitophilus oryzae, in grain commodities. Eisa, A. A.; Ammar, I. M. A. (Fac. Agric., Menoufia Univ., Shebin El-Kom, Egypt). Phytoparasitica, 20(1), 7-13 (English) 1992. CODEN: PHPRA2. ISSN: 0334-2123. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) Section cross-reference(s): 5 Ten insect growth regulators (IGRs): 4 juvenile hormone analogs (JHAs) (fenoxycarb, MV-678, R-20458, and dofenapyn), and 6 molt inhibitors (MIs) (triflumuron, chlorfluazuron, hexaflumuron, teflubenzuron, Dowco 439, and flufenoxuron); and the organophosphate malathion, were evaluated for residual activity in stored wheat for 2 yr against the rice weevil. Triflumuron, flufenoxuron, teflubenzuron, chlorfluazuron, hexaflumuron, and fenoxycarb, each at a concn. as low as 1 ppm a.i., were superior to 10 ppm malathion throughout the expt.Several substances with their cas registry numbers 101463-69-8 and 71422-67-8 may be metioned in this study. The 6 MIs, each tested at 50 and 100 ppm a.i., gave complete control for 2 yr. As low as 1 ppm a.i. of triflumuron, teflubenzuron, flufenoxuron, and chlorfluazuron had good residual activity for 1 yr, and provided almost complete grain protection during this period. Among the JHAs, fenoxycarb had the best residual activity. It gave almost complete control (96.6%) of S. oryzae for 18 mo at 100 ppm. The other JHAs at the 4 test concns. failed to produce this level of control. The viability of the wheat grain was not affected by any of the insecticidal treatments, with 90% germination recorded in treated and control grains at all intervals tested. .

The evaluation of a novel acylurea (flufenoxuron) on top fruit and citrus in Italy

The evaluation of a novel acylurea (flufenoxuron) on top fruit and citrus in Italy. Perugia, G.; Ingelsfield, C.; Tipton, J. D. (Shell Italia SpA, Milan, Italy). Proc. - Br. Crop Prot. Conf.--Pests Dis., (1), 315-22 (English) 1986. CODEN: PBCDDQ. ISSN: 0144-1612. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Flufenoxuron (I) [101463-69-8] was evaluated against insects and mites attacking a range of important crops. Results of efficacy trials in Italy show that I gives good control of the fruit tree red spider mite (Panonychus ulmi) and the leaf blister moth (Leucoptera scitella) on apples, and the citris red mite (P. citri) on oranges and clementines. The high level of acaricidal activity of I represents a significant extension of the spectrum of activity of acylureas. 101463-69-8 which is the cas registry number of one of substances is just one of reagents here. The results of studies on predatory mites, Amblyseius andersoni on apple and A. stipulatus on citrus, show that the effects of I are comparable with those std. products that are regarded as relatively harmless to these important predators. I is promising for use in integrated pest management programs. .
