Entomopathogenic nematodes (EPNs) (Rhabditida: Heterorhabditidae and Steinernematidae) are effective biocontrol agents for many insect pests generally stored a period of time prior to their use in the laboratory or field. However, unfavorable storage conditions have great impact on survival infectivity EPNs. This study was conducted determine optimum infective juveniles (IJs) four native EPN sp...

The potential for entomopathogenic nematodes to control ßies in cattle feedlots was determined by screening 40 strains representing 8 species of Heterorhabditis Poinar and 5 species of Steinernema Travassos for virulence toward 3rd-instar house ßies (maggots), Musca domestica L. None of the 22 strains of Heterorhabditis infecting maggots caused signiÞcant levels of mortality in a Þlter paper as...

A new entomopathogenic nematode in the genus Heterorhabditis is described from South Africa, from two singular isolates found 1000 km from each other, from beneath a fig tree and in a citrus orchard, respectively. Morphological and molecular studies indicate both isolates to be the same and a new undescribed Heterorhabditis species. Comparison of sequences of the internal transcribed spacer (IT...

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....

Diabrotica virgifera (Coleoptera: Chrysomelidae) is a serious pest that infects maize. Insecticides or entomopathogenic nematodes are used to control the root-damaging larvae. However, such treatments reportedly inconsistent in terms of efficacy under farming conditions. To better understand reasons behind these inconsistencies, we studied seed coatings, as clothianidin; granular soil insectici...

Entomopathogenic nematodes (EPNs) are known agents in pest biological control. Environmental factors can influence on populations of soil-inhabitant like EPNs agricultural lands. In the current study, after selecting a suitable study site (33.20-33.42 N and 48-48.55 E), soil sampling (250 samples) May to July 2019, infectious juveniles were extracted from samples according bait method. Accordin...

During the American Civil War, contemporary accounts describe a peculiar luminescence phenomenon associated with untreated injuries sustained by fallen troops after Battle of Shiloh (6-7 April 1862). While not experienced all soldiers, field surgeons observed that glow was somehow linked to reduced rates wound infection and better outcomes. Given wet springtime weather unsheltered overnight con...
