Strategus aloeus L (Coleoptera: Scarabaeidae), known as "Little bull" or oil palm "chiza" is a limiting pest in palm plantation in Cesar Colombia. Its management is based on pesticide use or old palm removal in renewal lots. Therefore, other alternatives are being sought out. Entomopathogenic nematodes isolated from the Colombian Andean region were evaluated. Under laboratory conditions S. aloe...

The South American tomato pinworm, Tuta absoluta (Meyrick) is one of the most serious insect pests plants. Current control strategies for T. primarily involve use insecticides, but increasing resistance in field populations has prompted research on alternative measures. Biological with entomopathogenic nematodes (EPNs) can be an or component Integrated Pest Management programme. In foliar appli...

T h e e n tomo p a t hogen i c n e m a t o d e Steinernema feltiae is compat ible with many chemical pesticides including insecticides, mi t i c ides , fung ic ides , and h e r b i c i d e s (1,3,4,7,9,10). Cer ta in o rganophospha t e and carbamate pesticides, however , adversely affect S. feltiae (5,6). Removal or dilution o f the pesticides with water usually results in ne ma t o d e recover...

The greenhouse whitefly Trialeurodes vaporariorum (Hemiptera: Aleyrodidae) is a polyphagous pest in greenhouse crops. The efficacy of two entomopathogenic nematodes (EPN), Steinernema feltiae and Heterorhabditis bacteriophora, as biological control agents against T. vaporariorum was evaluated using two model crops typical of vegetable greenhouse productions: cucumber and pepper. Laboratory test...

Depolanmış ürün zararlıları, tarım ürünlerin depolama sürecinde hasat sonrası ciddi kayıplara neden olan en önemli biyotik faktörlerden biridir. Bu zararlılar ile mücadele amacıyla yıllardır yaygınlıkla pestisitler kullanılmaktadır. Ancak pestisitlerin ve ne olduğu kalıntıların hedef dışı organizmalar üzerinde oluşturduğu toksik etkiler bilinmektedir. nedenle, alanlarında biyolojik mücadelede y...

A systematic program of genetic improvement was initiated by assessing the phenotypic variation of Steinernema feltiae strains for two traits assumed to limit efficacy: ultraviolet tolerance and host-finding ability. All of the strains assayed showed both low ultraviolet tolerance and poor host-finding ability, indicating that the likelihood of improving these traits through more extensive popu...
