Book excerpt: Excerpt from Field Experiments for the Control of Cabbage Insects The effectiveness of the materials was rated by recording the live loopers on four to five plants per plot, 4 to 5 days after each application. Percent reduction was calculated on the basis of the infestation in the treated as compared with that in the check plots. On the last examination the mature heads plus the outer leaves were removed and each leaf was examined for insects. At each examination the loopers were classified on the basis of size; small included newly hatched larvae up to one-half inch in length; medium, one-half to 1 inch; and large, 1 inch or longer. Pupae were included with the large larvae. An aphid colony ranged from 1 to 100 or more aphids. The possible phytotoxic effect of the materials on the plants was also noted.

This book was released on 2017-04-26 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively reviews current pest management practices and explores novel integrated pest management strategies in Brassica oilseed crops. It is essential reading for pest management practitioners and researchers working on pest management in canola and other Brassica crops worldwide. Canola, mustard, camelina and crambe are the most important oilseed crops in the world. Canola is the second largest oilseed crop in the world providing 13% of the world's supply. Seeds of these species commonly contain 40% or more oil and produce meals with 35 to 40% protein. However, its production has declined significantly in recent years due to insect pest problems. The canola pest complexes are responsible for high insecticide applications on canola. Many growers rely on calendar-based spraying schedules for insecticide applications. The diamondback moth Plutella xylostella and flea beetles Phyllotreta spp. (P. cruciferae and P. striolata)cause serious damage to canola. In the Northern Great Plains, USA, for instance, P. xylostella is now recorded everywhere that canola is grown. Severe damage to canola plants can be caused by overwintering populations of flea beetles feeding on newly emerged seedlings. Cabbage seed pod weevil (Ceutorhynchus obstrictus), swede midge (Contarinia nasturtii), and tarnished plant bug (Lygus lineolaris) are also severe pests on canola. Minor pests include aphids (cabbage aphid, Brevicoryne brassicae and turnip aphid, Hyadaphis erysimi) and grasshopper, Melanoplus sanguinipes.
