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 کاملبررسی بیمارگری دو گونه‌ی Steinernema carpocapsae و Heterorhabditis bacteriophora روی شب پره مینوز گوجه فرنگی (Tuta absoluta)
شب‌پره‌ی مینوز گوجه‌فرنگی Tuta absoluta یکی از آفات خطرناک مزارع گوجه‌فرنگی می‌باشد که در صورت طغیان تا 100% محصول را از بین می‌برد. در این بررسی به نقش بیمارگری لاروهای سن سوم (IJs) دو گونه‌ی Steinernema carpocapsae و Heterorhabditis bacteriophora روی سنین مختلف لاروی آفت مذکور درون ظرف پتری و درون برگ‌های جدا شده‌ی گوجه‌فرنگی پرداخته شده و نماتد کارآمدتر انتخاب شد. توانایی گونه‌ی مؤثرتر در آل...
متن کاملComparison of assays for the determination of entomogenous nematode infectivity.
Injection, contact, and soil assays were used to compare infectivity of Heterorhabditis bacteriophora strain HP88 and Steinernema carpocapsae strain All to final instar Galleria mellonella larvae. Under comparable assay conditions, H. bacteriophora produced less Galleria mortality and showed greater within-assay variability in infectivity than S. carpocapsae. Injection of individual S. carpocap...
متن کاملMorphometrics of Infective Juveniles of Steinernema spp. and Heterorhabditis bacteriophora (Nemata: Rhabditida).
Selected morphometrics of Heterorhabditis bacteriophora and seven species of Steinernema from in vivo culture were compared in relation to time of harvest. In addition, five Steinernema species were reared in vitro and their morphometrics were compared with those from in vivo culture. With in vivo culture, there was generally a negative linear relationship between body length of infective juven...
متن کاملInteraction of the Koinobiont Parasitoid Microplitis rufiventris of the Cotton Leafworm, Spodoptera littoralis, with Two Entomopathogenic Rhabditids, Heterorhabditis bacteriophora and Steinernema carpocapsae
Entomopathogenic nematodes are generally considered beneficial organisms. However, they can affect beneficial insects such as parasitoids. The interaction between the entomopathogenic nematodes Heterorhabditis bacteriophora Poinar (Rhabditida: Heterorhabditidae) and Steinernema carpocapsae Weiser, and the parasitoid Microplitis rufiventris Kokujev (Hymenoptera: Braconidae) was investigated in t...
