Mechanisms of resistance in broccoli, Brassica oleracea italica to the garden symphylan, Scutigerella immaculata (Newport)

Creator:: Simagrai, Montri
Abstract:: Studies were conducted on the mechanisms contributing to resistance in broccoli, Brassica oleracea italica, to the garden symphylan, Scutigerella immaculata (Newport). Differences in resistance to symphylan injury were shown between five selected broccoli cultivars. The hybrid cultivars, Crusader, Green Duke and Bravo, showed a higher level of resistance to symphylans...

Biology and population regulation of the strawberry root weevil, Otiorhynchus ovatus (L.) (Coleoptera:Curculionidae)

Creator:: Emenegger, Donald Brian
Abstract:: The life history of the strawberry root weevil, Otiorhynchus ovatus (L.), on peppermint was studied in the Willamette Valley of Oregon to provide the information necessary to develop effective control measures. Adult weevils emerged from the soil from late May until mid- June and were active in the field until...

The response of scutigerella immaculata to naturally occurring chemical stimuli

Creator:: Reeve, Daniel Hart
Abstract:: A study was conducted of the response of the garden symphylan, Scutigerella immaculata (Newport), to naturally occurring chemicals. Results of olfactometer studies with plant odors were inconclusive because air currents in one olfactometer and the shape of another had undesirable effects on symphylan behavior. Non-random distributions of symphylans in chambers...

Temperature-dependent development of strawberry root weevil Otiorhynchus ovatus (L.)

Creator:: Umble, Jon R.
Abstract:: The temperature-dependent development of pupae and adults of strawberry root weevil (SRW) Otiorhynchus ovatus (L.) was studied in strawberry (Fragaria x ananassa Duch. var. 'Totem'). The development of pupae and adults was investigated at constant temperatures from 3-33°C at 3°C intervals. Major emphasis was on the development of a weighted...

Population development of Scutigerella immaculata (Newport), in laboratory and greenhouse cultures

Creator:: Ramsey, Henry Lee
Abstract:: Population development of the symphylan, Scutigerella immaculata (Newport), was studied in laboratory cultures. Also symphylan injury to greenhouse plants was investigated. Plastic polyethylene containers partly filled with damp ground hemlock bark were used to culture symphylan in the laboratory. Fresh lettuce food was supplied to the cultures weekly. Factors which...

Insect pests of economic importance on cereal crops in the Senegal River Basin, West Africa

Creator:: Sy, Adama
Abstract:: Cereal crops cultivated in Mali, Mauritania and Senegal consist primarily of sorghum, millet, rice and maize. They form the gramineous crops that, are programmed for the agricultural improvement of the Senegal River Basin. Twelve economically important insect pests on these crops were selected for study and treated with regard to...
