Some interactions ofSerratia marcescens nucleopolyhedrosis virus andBlepharipa pratensis [Dip.: Tachinidae] inLymantria dispar [Lep.: Lymantriidae]

Abstract: The entomopathogens Serratia marcescens Btzm and nucleopolyhedrosis virus were each fed alone and in combination with the parasite Blepharipa pratensis (MEIGEN) tO 4th-instar gypsy moth, Lymantria dispar, (L.) larvae.At LD30 for NPV, the presence of the parasite enhanced polyhedrosis about 30 ~ but the total number of gypsy moth larvae and pupae killed (85 %) was not significantly different from the number killed by the parasite alone (93 %). When the parasite was combined with S. marcescens, a strain nonpatho… Show more

“…Under laboratory conditions A. melanoscelus has been found capable of transmitting NPV (Raimo et aL, 1977). We have shown that the.presence ofBlepharipa pratensis (Meigen) in stage IV larvae enhanced deaths to NPV by about 38.7 % (Godwin & Shields, 1982).B. pratensis is thought to be the most successful insect parasite of L. dispar (PsehornWaleher, 1974 ; Angalet, 1974 (1)).…”

“…Several investigators (Bueher, 1963 ;Bracken & Bneher, 1967 ;Bueher & Williams, 1967 ;King et aL, 1975 ;Goodwin & Shields, 1982 ; and others) reported on effects of opportunistic pathogens and microbial contaminants of the hosts on the development of parasitoids. In general, opportunistic pathogens and microbial contaminants negatively affected parasitoid development and in some instances caused serious reduction in adults produced or even totally eliminated parasitoid colonies.…”
