چکیده
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 yaygın olarak kullanılan Entomopatojen Nematodların (EPN), Sitophilus oryzae L., 1763 (Coleoptera: Curculionidae)'nin potansiyel kontrolünde kullanılabileceği düşünülmektedir. çalışmada Steinernema feltiae TUR-S3 carpocapsae TUR-S4 izolatlarının (Rhabditida: Steinernema) S. oryzae' nin erginleri üzerindeki biyokontrol 8 farklı konsantrasyonda [250 IJs/cm2 (600 IJs/ergin), 200 (480 100 (240 50 (120 25 (60 12 (30 6 (15 3 (7.5 IJs/ergin)] değerlendirilmiştir. Sonuçlara göre hem izolatı hemde izolatı, erginlerinde yüksek ölüm oranını (96.67%) 250 uygulama konsantrasyonunda gerçekleştirmiştir. için etkili LC50 LC90 değerleri sırasıyla 47.55 167.16 dir. değerler 35.66 121.79 elde edilmiştir.

The Effect of Metal Ions on Mortality, Pathogenicity and Reproduction of Entomopathogenic Nematodes Steinernema feltiae Filipjev {Rhabditida, Steinernematidae)
The effect of cadmium, copper, lead, zinc, manganese and magnesium on entomopathogenic nematodes S. feltiae was tested under laboratory conditions. The mortality of nematode invasive larvae, their pathogenicity expressed as test insect G. mellonella mortality and reproduction from the test insect bodies were investigated. It was revealed that cadmium, copper, lead and zinc affected an increase ...

In Slovenia only recently entomopathogenic nematodes were recorded for the first time. In the beginning of 2007, the presence of Steinernema affine was confirmed. During the further investigations in the same year Steinernema feltiae was recorded on the arable field near Cerknica. In the previous year this field was planted with chicory. In Slovenia, until now the entomopathogenic nematodes had...

In April 2008, 120 soil samples from 24 locations were collected in Gorenjska, Notranjska and Primorska regions as well as in Ljubljansko barje. The presence of entomopathogenic nematodes was confirmed in 9 samples from 6 locations. Only the sample C101, which was taken in the village Svino in the area of Breginjski kot (western part of Slovenia, the vicinity of Italian border), was sent to gen...

A nematode collected from Diaprepes abbreviatus is identified and described as a new species, Steinernema diaprepesi n. sp. The new species is closely related to S. feltiae, S. glaseri, and S. oregonense and can be distinguished from these species by the following characteristics: Males: Spicule averaging 79 (71-90) microm and spicule shape; D% (distance from anterior end to excretory pore/ eso...

Larvae, pupae, and adults of the carrot weevil (Listronotus oregonensis) were infected and killed by the three entomophagous nematodes (Steinernema feltiae, S. bibionis, and Heterorhabditis heliothidis) under controlled conditions. Third-stage larvae were more susceptible than pupae or adults. S. feltiae and S. bibionis were the most aggressive nematode species, causing larval mortality after 2...
