Virulence of commercial strains entomopathogenic nematode (EPN) Steinernema carpocapsae (Weiser), feltiae Filipjev and Heterorhabditis bacteriophora Poinar (Rhabditida: Steinernematidae, Heterorhabditidae), were tested on young females Pulvinaria hydrangeae Steinweden, Partenolecanium corni (Bouché) Coccus pseudomagnoliarum (Kuwana) (Hemiptera, Coccidae) a native strain H. was citricola scale, ...

Entomopathogenic nematodes (EPNs) are obligate parasites of insects. EPNs generally have a broad host range, easily mass reared, and can kill some insects within 48 h. safe for vertebrates, plants, other non-target organisms. However, disadvantages that make them less effective against foliar insect pests such as sensitivity to desiccation, ultraviolet (UV) radiation, high temperatures. The goa...

Chemical insecticides are intensively used in agriculture which cause negative effects on environmental sustainability by increasing pest tolerance and continuous action local fauna. In contrast to chemical insecticides, biological target specific pests, minimizing their impact the surrounding environment. However, most of natural available market expensive for farmers Central Asian region. Thi...

Abstract The soil-dwelling nematode Steinernema feltiae is found across a wide range of environmental conditions. We asked if its only bacterial symbiont, Xenorhabdus bovienii , shows intraspecific variability in thermal range, which may affect effectiveness S. against host insects. isolated X. from six different natural locations with mean annual temperatures and two laboratory cultures. estim...
