Classical Biological Control of Bemisia tabaci in the United by Juli Gould, Kim Hoelmer, John Goolsby

By Juli Gould, Kim Hoelmer, John Goolsby

This booklet stories the interagency study and improvement attempt on classical organic regulate within the united states from 1992-2002. The winning exploration, importation, screening, overview, rearing, and institution of at the least 5 unique Bemisia tabaci common enemies in fast reaction to the devastating infestations within the united states is a landmark in interagency cooperation and coordination of a number of disciplines. during this quantity, a number of the authors current distinct reports of average enemy exploration, advent, and assessment efforts that may function a advisor to aid and inspire classical organic keep watch over inputs into different built-in pest administration platforms.

Emiratus. Although these had a unique PCR banding pattern, Rose and Zolnerowich (personal communication) were unable to find clear morphological characteristics to distinguish it from Eret. emiratus. The Ethiopian Eretmocerus subsequently became established in Arizona, Texas and California. Little is known about the climate of Melka Werer where the parasitoid was originally collected, which is a high, tropical desert unlike any of the locations in the USA where it has established. It was speculated that the distribution of the parasitoid probably extends down to the Red Sea near Djibouti and Eritrea, where the climate is hot, arid desert similar to the Persian Gulf and to the drier parts of the southwestern USA.

1999), and others. A broad range of activity has been observed. The most virulent isolates produced 50% mortality in B. tabaci biotype B nymphs at 50–150 spores/ cm2. Some of the isolates that originated from hosts other than whiteflies are as active against Bemisia as isolates from whiteflies (Vidal et al. 1997b). One of the most virulent isolates studied by Osborne et al. (1990b) is the active component of PFR-97 (20% Water Disperable Granules), a commercially produced microbial insecticide.
