Phased activity in Heterorhabditis megidis infective juveniles.
The infectivity of Heterorhabditis megidis infective juveniles (IJs) increases during storage in water. We investigated whether this change can be related to other features of the IJs' behaviour. IJs were stored in water for 4 weeks at 20 degrees C, and the following parameters were assessed at intervals: infectivity for Galleria mellonella, dispersal in sand, host-finding on agar, and the perc...
متن کاملVertical Migration of Heterorhabditis bacteriophora and H. heliothidis (Nematoda: Heterorhabditidae) in Sandy Loam Soil.
The entomogenous nematodes Heterorhabditis bacteriophora Poinar and H. heliothidis (Khan, Brooks, and Hirschmann) and their associated bacterium Xenorhabdus luminescens (Poinar and Thomas) have been tested against a humher of insect pests with some encouraging results (11). Simons (14) obtained 90% control of tile black vine weevil, Otiorhynchus sulcatus Fab., after applying Heterorhabditis sp....
متن کاملMass Production of the Entomogenous Nematode Heterorhabditis heliothidis (Nematoda: Heterorhabditidae) on Artificial Media.
Heterorhabditis heliothidis is reared monoxenically on an artificial medium consisting of commercially available nutrient broth, yeast extract, and vegetable oil. These components are cooked with flour and coated onto polyether polyurethane sponge, autoclaved, inoculated with a suspension of the bacterial symbiont of the nematode, and incubated at 25 C for 3 d. The bacterial garden on sponge pr...
متن کاملEFFECT OF MINI-SPRINKLER IRRIGATION SYSTEM ON Heterorhabditis baujardi LPP7 (NEMATODA: HETERORHABDITIDAE) INFECTIVE JUVENILE
Entomopathogenic nematodes (EPNs) are currently being used as successful biological control agents of soil-dwelling insect pests. Previous field and greenhouse studies demonstrated that application techniques and non-biotic factors (temperature and pressure) have a significant effect on EPNs efficacy. The objective of this study was to evaluate the influence of an irrigation spray application s...
متن کاملEffects of Paenibacillus nematophilus on the entomopathogenic nematode Heterorhabditis megidis.
The insect parasitic nematodes Heterorhabditis spp. are mutualistically associated with entomopathogenic bacteria, Photorhabdus spp. A novel association has been detected between H. megidis isolate EU17 and the endospore-forming bacterium Paenibacillus nematophilus. P. nematophilus sporangia adhere to infective juveniles (IJs) of H. megidis and develop in insect hosts along with the nematodes a...
