Variability in Plutella and its natural enemies: implications for biological control
Since 1996, as part of a cooperative ARS/CIRAD Plutella biocontrol program, 115 Plutella populations have been collected in 32 countries from cole crops and cruciferous weeds. Twenty-seven primary hymenopterous parasitoid species were found, especially Diadegma spp., Cotesia plutellae and Oomyzus sokolowskii. A number of fungal pathogens, isolates of Paecilomyces fumosoroseus, Paecilomyces sp.,...
متن کاملAcquired Natural Enemies of the Weed Biological Control Agent Oxyops Vitiosa (colepotera: Curculionidae)
The Australian curculionid Oxyops vitiosa Pascoe was introduced into Florida in 1997 as a biological control agent of the invasive tree Melaleuca quinquenervia (Cav.) S. T. Blake. Populations of the weevil increased rapidly and became widely distributed throughout much of the invasive tree’s adventive distribution. In this study we ask if O. vitiosa has acquired natural enemies in Florida, how ...
متن کاملBt crops benefit natural enemies to control non-target pests
Crops producing insecticidal crystal (Cry) proteins from Bacillus thuringiensis (Bt) control important lepidopteran pests. However, pests such as aphids not susceptible to Cry proteins may require other integrated pest management (IPM) tactics, including biological control. We fed aphids on Bt and non-Bt plants and analyzed the Bt protein residue in aphids and compared the effects of Bt plants ...
متن کاملNatural Insect Enemies for the Control of Chromolaena Odorata
Chromolaena odorata (L.) King & Robinson (Asteraceae: Eupatorieae), a shrub of neotropical origin, is a primary threat to the conservation of biodiversity, and to pastoral and crop agriculture and forestry in the subtropical regions of South Africa. It invades much of the sugarcane growing areas in KwaZulu-Natal and thus impacts negatively on the South African sugar industry. The plant presents...
متن کاملThe Natural Enemies of Locusts
Fig. T. Redwing Locust, dead from Beauucria globlllifera. (Natural size). that death occurs about six to eight days after infection. The infected insect ceases feeding, wanders aimlessly about, and just before death hides in a shady spot on or near the ground. The bottom of the cane stools are favourite places. After death, the whole of the inside of the insect is full of a white growth of fung...
