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...

Effects of tillage on emergence of mint root borer, Fumibotys fumalis Guenée, and on other agronomic factors in peppermint, Mentha piperita L.

Creator:: Talkington, Michael Lee
Abstract:: Studies were conducted in the Willamette Valley of western Oregon to evaluate the effects of plowing (7.5-15 cm deep) and disking (5-10 cm deep) in peppermint, Mentha piperita L., on the following factors: 1) emergence of adult "mint root borer", Fumibotys fumalis Guenée; 2) suppression of common groundsel, Senecio vulgaris...

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...

Entomopathogenic nematodes for biological control of the Colorado potato beetle, Leptinotarsa decemlineata (Say)

Creator:: Armer, Christine Andrea
Abstract:: The Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), is the most devastating foliage-feeding pest of potatoes in the United States. Potential biological control agents include the nematodes Heterorhabditis marelatus Liu & Berry and Steinernema riobrave Cabanillas, Poinar & Raulston, which provided nearly 100% CPB control in previous laboratory trials. In...
