Cryopreservation of Steinernema carpocapsae and Heterorhabditis bacteriophora.
A method for the cryopreservation of third-stage infective juveniles (IJ) of Steinernema carpocapsae and Heterorhabiditis bacteriophora was developed. Cryoprotection was achieved by incubating the nematodes in 22% glycerol (S. carpocapsae) or 14% glycerol (H. bacteriophora) for 24 hours, followed by 70% methanol at 0 C for 10 minutes. The viability of S. carpocapsae frozen in liquid nitrogen as...
متن کاملa comparative study of the theme of "marriage" in three victorian novelists: charles dickens, george eliot and thomas hardy
این تحقیق کوشیده است با انتخاب پنج رمان از میان آثار برگزیده، «چارلز دیکنز»، «جورج الیوت» و «توماس هاردی » و با رویکردی تطبیقی به بررسی درونمایه ی «ازدواج» در آثار این سه رمان نویس بزرگ دوره ی ویکتوریا بپردازد. فرضیه ی اولیه ی تحقیق این بوده است که چارلز دیکنز (1870- 1812) با زبانی شوخ و گزنده، جورج الیوت(1880- 1819) با نگاهی آموزشی–اندرزگونه و توماس هاردی(1928- 1840) با رویکردی تلخ وانتقادی به...
Vertical Migration of Heterorhabditis bacteriophora and H. heliothidis (Nematoda: Heterorhabditidae) in Sandy Loam Soil.
The entomogenous nematodes Heterorhabditis bacteriophora Poinar and H. heliothidis (Khan, Brooks, and Hirschmann) and their associated bacterium Xenorhabdus luminescens (Poinar and Thomas) have been tested against a humher of insect pests with some encouraging results (11). Simons (14) obtained 90% control of tile black vine weevil, Otiorhynchus sulcatus Fab., after applying Heterorhabditis sp....
متن کاملPhased activity in Heterorhabditis megidis infective juveniles.
The infectivity of Heterorhabditis megidis infective juveniles (IJs) increases during storage in water. We investigated whether this change can be related to other features of the IJs' behaviour. IJs were stored in water for 4 weeks at 20 degrees C, and the following parameters were assessed at intervals: infectivity for Galleria mellonella, dispersal in sand, host-finding on agar, and the perc...
متن کاملEntomopathogenic Nematode Genome Consortium: Sequencing and Annotation of Heterorhabditis bacteriophora Project Summary: This project aims to sequence the genome of the entomopathogenic nematode Heterorhabditis bacteriophora strain TTO1
Heterorhabditis bacteriophora Project Summary: This project aims to sequence the genome of the entomopathogenic nematode Heterorhabditis bacteriophora strain TTO1 as a representative of 45 other species that are used as biological control agents for insect pests worldwide. This nematode is closely related to the two already sequenced free-living nematodes, Caenorhabditis elegans and C. briggsae...
