Autor: R. A. Van Steenwyk, H. T. Reynolds, Nick C. Toscano, V. Sevacherian

Publikováno v: Journal of Economic Entomology. 72:144-147

Degree-day (dd) accumulation was used as a means of forecasting moth population peaks of Pectinophora gossypiella (Saunders). Male moths exhibited cyclic population peaks at intervals of 23176±1154 dd’s. These findings should reduce the monitoring

Dosage-Mortality Studies with Pyrethroids and Other Insecticides on the Tobacco Budworm (Lepidoptera: Noctuidae) from the Imperial Valley, California

Autor: H. T. Reynolds, J. L. Martinez-Carrillo

Publikováno v: Journal of Economic Entomology. 76:983-986

Dosage-mortality studies were conducted on populations of the tobacco budworm, Heliothis virescens (F.), from the Imperial Valley of California in 1979, 1980, and 1981. Progeny of field-collected budworms showed a steady increase in resistance over t

Relative Susceptibility and Resistance of the Tobacco Budworm to Methyl Parathion and Synthetic Pyrethroids in Southern California1

Autor: H. T. Reynolds, P. H. Twine

Publikováno v: Journal of Economic Entomology. 73:239-242

Various collections of Heliothis virescens (F.) from different locations in southern California were tested for resistance to methyl parathion, fenvalerate, and cis-permethrin using the topical application methods on 8 mg larvae. Baseline levels of s

Marking Pink Bollworm with Rubidium1

Autor: R. A. Van Steenwyk, A. L. Page, Gregory R. Ballmer, H. T. Reynolds

Publikováno v: Annals of the Entomological Society of America. 71:81-84

The feasibility of marking native pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae), with rubidium (Rb) was studied. When Rb was incorporated in the larval diet of pink bollworm, there was a significant increase in the Rb
