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...

Management of variegated cutworm in peppermint

Creator:: Coop, Leonard Bryan
Abstract:: A pest management program for variegated cutworm (VC), Peridroma saucia (Hubner), in Oregon peppermint was developed based on studies of pheromone trapping, sampling methods, and economic thresholds. Pheromone traps effectively trapped VC males and were used to reflect development and oviposition trends. Trap height was linearly correlated to moth catch...

Sampling methods, biology and management of the mint flea beetle in central Oregon peppermint

Creator:: Morris, Mark A.
Abstract:: Sampling techniques were evaluated to quantify immature mint flea beetle (MFB), Longitrsus waterhousei Kutschera (Coleoptera: Chrysomelidae), on peppermint (Mentha piperita L.), in central Oregon. During the study period, 1985-1988, soil samples of 350 cm³ were effective for collecting immature MFB. Sifting soil samples through screens was effective for estimating post-feeding...

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...

Studies on resistance of rice to Sogatodes oryzicola (Muir) and a parasitoid, Haplogonatopus sp., in Costa Rica

Creator:: Alvarez B., Francisco
Abstract:: Twenty-one rice cultivars were evaluated to determine the difference between populations of Sogatodes oryzicola (Muir) (Homoptera: Delphacidae) in Costa Rica and Colombia, Survival, mortality and population development of S. oryzicola on five selected cultivars was used to determine levels of plant resistance. The importance and potential of the parasitoid-predator Haplogonatopus...

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...

Toxicity of peppermint monoterpenes to the variegated cutworm, Peridroma saucia Hübner

Creator:: Harwood, Steven Hunter
Abstract:: The toxicity of menthol, menthone, pulegone, limonene, and a-pinene, five monoterpenes found in peppermint (Mentha piperita L.), to the variegated cutworm (Peridroma saucia Hiibner) was characterized by in vivo and in vitro methods. Pulegone and menthone caused slower growth over six days when incorporated into an artificial diet and fed...
