Infection of the Entomopathogenic Nematode, Steinernema carpocapsae, as Affected by the Presence of Steinernema glaseri.
The infection behavior of Steinernema carpocapsae infective juveniles (IJ) was investigated in the presence and absence of S. glaseri. Mixed inoculation of S. carpocapsae with S. glaseri IJ significantly raised the nictation rates of S. carpocapsae IJ. Significantly more S. carpocapsae IJ migrated to the host insect in the mixed inoculation with S. glaseri IJ on agar plates. More S. carpocapsae...
متن کاملAttenuated Virulence and Genomic Reductive Evolution in the Entomopathogenic Bacterial Symbiont Species, Xenorhabdus poinarii
Bacteria of the genus Xenorhabdus are symbionts of soil entomopathogenic nematodes of the genus Steinernema. This symbiotic association constitutes an insecticidal complex active against a wide range of insect pests. Unlike other Xenorhabdus species, Xenorhabdus poinarii is avirulent when injected into insects in the absence of its nematode host. We sequenced the genome of the X. poinarii strai...
متن کاملCharacterization of Xenorhabdus (γ-Proteobacteria) strains associated bacteria with the Steinernema (Nematoda: Steinernematidae) isolates from Iran
باکتریهای Xenorhabdus همزیست اختصاصی نماتدهای بیمارگرحشرات در جنس Steinernema میباشند. در این بررسی مشخصات سه جدایهی باکتری جدا شده از دو گونه نماتد بیمارگر حشرات Steinernema glaseri (Steiner) وS. carpocapsae (Weiser) تعیین شده است. این دو گونهی بیمارگر از جمعیت طبیعی لاروهای کرم سفید ریشه، Polyphylla olivieri (Laporte de Castelnau)، جداسازی شدند. مطالعهی حاضر بر روی مشخصات اختصاصی این جدایههای...
متن کاملDescription of Xenorhabdus khoisanae sp. nov., the symbiont of the entomopathogenic nematode Steinernema khoisanae.
Bacterial strain SF87(T), and additional strains SF80, SF362 and 106-C, isolated from the nematode Steinernema khoisanae, are non-bioluminescent Gram-reaction-negative bacteria that share many of the carbohydrate fermentation reactions recorded for the type strains of recognized Xenorhabdus species. Based on 16S rRNA gene sequence data, strain SF87(T) is shown to be closely related (98% similar...
متن کاملDevelopmental temperature effects on five geographic isolates of the entomopathogenic nematode Steinernema feltiae (Nematoda: Steinernematidae).
The development of five geographic isolates of Steinernema feltiae at 5, 8, 10, 15, 20, 25, and 28 degrees C in wax moth, Galleria mellonella, larvae was examined. The isolates were from Mediterranean (Sinop from Turkey, SN from France, and Monterey from California), subtropical (Rafaela from Argentina), and tropical (MG-14 from Hawaii) regions. All isolates caused 100% mortality of wax moth la...
