Optimizing Trichogramma ostriniae (Hymenoptera: Trichogrammatidae) releases to control European corn borer, Ostrinia nubilalis (Lepidoptera: Crambidae) in bell pepper
The effective dispersal ability of the egg parasitoid Trichogramma ostriniae Pang and Chen was assessed in potato fields on the Eastern Shore of Virginia in spring 2005 and 2006. Approximately 0.5 million T. ostriniae were released from a central release point in separate potato fields. Dispersal was monitored using yellow sticky card traps and European corn borer, Ostrinia nubilalis Hübner, eg...
متن کاملPotential of Trichogramma ostriniae (Hymenoptera: Trichogrammatidae) for biological control of European corn borer (Lepidoptera: Crambidae) in solanaceous crops.
We assessed the ability of Trichogramma ostriniae (Peng & Chen) to locate and parasitize Ostrinia nubilalis (Hübner) eggs in crops other than corn, and we evaluated the efficacy of inundative releases of the parasitoid in two solanaceous crops, pepper and potato. Despite a greater plant surface area to search, parasitism of O. nubilalis eggs was consistently higher in sweet corn than dicotyledo...
متن کاملSelectivity of neem to Trichogramma pretiosum Riley and Trichogrammatoidea annulata De Santis (Hymenoptera: Trichogrammatidae).
Trichogramma pretiosum Riley and Trichogrammatoidea annulata De Santis are commonly found in avocado and persimmon orchards in northern Parana state. However, their abundance depends on whether insecticides are used or not to control the key lepidopteran pests Stenoma catenifer (Wals.) (Lepidoptera: Elachistidae) and Hypocala andremona (Stoll) (Lepidoptera: Noctuidae), respectively. The aim of ...
متن کاملHost‐plant associated genetic divergence of two Diatraea spp. (Lepidoptera: Crambidae) stemborers on novel crop plants
Diatraea lineolata and Diatraea saccharalis (Lepidoptera: Crambidae) are moths with stemboring larvae that feed and develop on economically important grasses. This study investigated whether these moths have diverged from a native host plant, corn, onto introduced crop plants including sorghum, sugarcane, and rice. Diatraea larvae were collected from these four host plants throughout the year i...
متن کاملDeveloping Trichogramma (Hymenoptera: Trichogrammatidae) as a pest management tool
The egg parasitoid, Trichogramma (Hymenoptera: Trichogrammatidae), is used extensively around the world as a biological control agent for the control of lepidopterous pests. Wasps are either released to augment an existing population “inoculative release,” or they are released in large numbers to coincide with maximum pest pressure “inundative release.” Field releases however, have had variable...
