Abstract

A genetically improved strain of the parasite Trioxys pallidus performed well after release in commercial orchards in 1988, persisting through the season in four of the five release sites and, at two sites, dispersing to nearby wainut blocks. Work on the resistant strain also continued in the laboratory, as reported in the next article.
