The Use of Temperature Accumulations and Sequential Sampling in Predicting Damaging Populations of Blissus leucopterus hirtus1

Autor: F. L. Mcewen, H. J. Liu

Publikováno v: Environmental Entomology. 8:512-515

The initiation of post-diapause development in Blissus leucopterus hirtus was marked by oogenesis in overwintered females. Its temperature threshold was established as 7°C. Sequential sampling and chemical applications were timed from a knowledge of

GENETIC INSECT CONTROL: CHROMOSOME REARRANGEMENTS ISOLATED USING A SIMPLE SYSTEM IN THE ONION MAGGOT, HYLEMYA ANTIQUA (DIPTERA: ANTHOMYIIDAE)

Autor: J. A. Keith Reid, F. L. McEwen

Publikováno v: The Canadian Entomologist. 109:1287-1291

A method for the direct isolation of useful genetic strains was shown effective in the onion maggot. This method circumvents the extensive preliminary investigations called for by current concepts in genetic population control. From genomes treated w

Field tests, in which several insecticides were applied at equal rates by ground sprayer to oats, rye and alfalfa, showed that residues 1 h after application were much lower for highly volatile compounds than for those of lower volatility. Varying th
