Status, distribution and seasonal variation of filbert aphid resistance to selected insecticides in the Willamette Valley, Oregon

Creator:: Katundu, Juma
Abstract:: Levels of resistance to six selected insecticides of eleven field populations of the filbert aphid Mvzocallis coryli (Goetze) were determined by using the leaf-dip residue technique. Test insecticides included compounds widely used in commercial filbert orchards, namely, carbaryl, diazinon, endosulfan, phosalone, fenvalerate and oxydemetonmethyl. Aphid samples were collected within a...

Seasonality of codling moth, Cydia pomonella L. (Lepidoptera: Olethreutidae) in the Willamette Valley of Oregon : role of photoperiod and temperature

Creator:: Setyobudi, Lilik
Abstract:: The seasonality, relationship of temperature and photoperiod to growth and post-diapause development, and overwintering behavior of codling moth, Cydia pomonella L., (Lepidoptera: Olethreutidae) were studied over a three year (1986-1989) period. The developmental threshold varied from a low of 9.66°C for the second instar to a high of 14.23°C for...

Systematics and host associations of Ormyrus species (Hymenoptera: Chalcidoidea)

Creator:: Hanson, Paul E.
Abstract:: The genus Ormyrus has a worldwide distribution and comprises about sixty recognized species. The higher taxonomic relationships of the genus are uncertain, as evidenced by its placement in the families Ormyridae, Pteromalidae, or Torymidae. Here, the genus is described in detail and a preliminary catalog of the world species is...
