Vapor heat treatments were developed against life stages of the mealybug Maconellicoccus hirsutus (Green) (Homoptera: Pseudococcidae). Treatments tested were 47 degrees C for 5-50 min in 5-min increments and 49 degrees C for 3, 5, 8, 10, and 12 min. All tests were conducted with mixed age M. hirsutus on Chinese pea, Pisum sativum L.

An efficient transformation system for the basidiomycete Coriolus hirsutus was developed. A double-auxotrophic mutant of C. hirsutus, deficient both in ornithine carbamoyltransferase (OCTase) and 3-isopropylmalate dehydrogenase (3-IPM dehydrogenase), was transformed to Arg+ with each allelic type of the C. hirsutus genomic OCTase gene (arg1) newly cloned. The transformation frequency of 10(3)-1...
