Cloning Serratia entomophila antifeeding genes--a putative defective prophage active against the grass grub Costelytra zealandica.
Serratia entomophila and Serratia proteamaculans (Enterobacteriaceae) cause amber disease in the grass grub Costelytra zealandica (Coleoptera: Scarabaeidae), an important pasture pest in New Zealand. Larval disease symptoms include cessation of feeding, clearance of the gut, amber coloration, and eventual death. A 155-kb plasmid, pADAP, carries the genes sepA, sepB, and sepC, which are essentia...
متن کاملPOPULATION STUDIES OF GRASS GRUB (Costelytra zealandica) AND BLACK BEETLE (Heteronychus arator) (COLEOPTERA: SCARABAEIDAE)
Population studies of grass grub and black beetle have revealed simple patterns of population determination. Populations fluctuate in response to variations in soil moisture and temperature. The upper limit to population growth is set by density dependent factors (larval mortality of grass grub and variation in natality of black beetle). Parasites and predators appear to be generally unimportan...

متن کاملBiocontrol Potential of Entomopathogenic Nematodes Heterorhabditis and Steinernema Against Second Instar Grub of White grub, Leucopholis lepidophora (Blanchard)
The effectiveness of two entomopathogenic nematodes (EPN) viz., Heterorhabditis indica strain NBAII-104 and Steinernema carpocapsae strain NBAII-04 against second instar grubs of L. lepidophora (Blanchard) under pot culture experiment. At a concentration of 450 IJs ml, H. indica recorded highest mortality (87.60%) at 15 DAT. While, S.carpocapsae recorded 54.05 per cent grub mortality at 450 IJs...
