Enhancement of biological control with beneficial insectary plantings

Creator:: Colley, Micaela Ruth
Abstract:: Five field experiments were conducted to evaluate the relative attractiveness of potential beneficial insectary plants to aphidophagous hover flies and parasitic Hymenoptera and the effectiveness of interplanting selected flowering plants in a broccoli field to enhance biocontrol of the cabbage aphid and green peach aphid. In 1996 we established a...

Behavior of Drosophila suzukii in Relation to Abiotic, Biotic, and Nutrient Factors

Creator:: Park, Kyoo Rok
Abstract:: Drosophila suzukii (Diptera: Drosophilidae), is a serious pest in soft and stone fruit industries worldwide. The unique serrated ovipositor of female Drosophila suzukii allowed the species to reproduce in intact, ripening fruit before the harvest. Current control methods rely heavily on insecticide application, only becoming less profitable due to the...

Cryopreservation of Shoot Tips: Antioxidant Investigations with Rubus and Protocols for Mentha and Vaccinium

Creator:: Uchendu, Esther Eyiuche
Abstract:: Oxidative stress that occurs during cryopreservation may be reduced by the addition of antioxidants. Vitamin E (Vit E), Vitamin C (Vit C), glutathione (GSH), lipoic acid (LA), glycine betaine (GB) and polyvinylpyrrolidone (PVP) were applied at four steps of the PVS2 vitrification protocol (pretreatment, loading, rinsing, and regrowth). Shoot tips...
