The ability of entomopathogenic nematodes to tolerate environmental stress such as desiccating or freezing conditions, can contribute significantly to biocontrol efficacy. Thus, in selecting which nematode to use in a particular biocontrol program, it is important to be able to predict which strain or species to use in target areas where environmental stress is expected. Our objectives were to ...

Bu çal??mada Türkiye ve K?rg?zistan’a ait Entomopatojen nematod (EPN) izolatlar?ndan Heterorhabditis bacteriophora türüne iki (11KG TOK20) Steinernema feltiae (3KG Tokat-Emir) izolat?n, depolanm?? fasulye zararl?s? olan tohum böce?i (Acanthoscelides obtectus Say. Coleoptera: Bruchidae)’ne kar?? etkinli?i ortaya konmu?tur. Tek doz denemeleri, en yüksek etkiyi S. feltiae’nin her 2 izolat? gösterm...

Temperature gradient fluctuations that occur naturally as a result of heating and cooling of the soil surface were reproduced within 15-cm-d, 15-cm-long acrylic tubes filled with moist sand. Sunny and rainy periods during the late summer in eastern Texas were simulated. Five ecologically different nematode species were adapted to fluctuating temperatures for 20-36 hours at a simulated depth of ...

The recent invasion of the Japanese beetle Popillia japonica Newman (Coleoptera: Scarabaeidae) in northern Italy offered opportunity to explore entomopathogenic nematodes (EPNs) associated with soil hay meadows. A total 61 sites were considered for nematode sampling, and from 17 them (27.9%) EPNs isolated further characterized molecular morphological techniques as well laboratory bioassays. Two...

Entomopathogenic nematodes are soil-dwelling biocontrol agents. EPNs need an insect host to complete their life cycle, and they kill during its development. The major disadvantage of is the high cost commercial products. Thus, there many studies focused on reducing production costs by optimization mass production. In a previous project, Heterorhabditis bacteriophora Poinar, 1976 (Rhabditida: He...
