Emergence of Steinernema feltiae from infected Galleria mellonella cadavers in moist and dry conditions

A. M. Rahoo, T. Mukhtar, S. R. Gowen, B. Pembroke, M. A. Rahu

Entomopathogenic nematodes (EPN) are one of the promising alternatives to synthetic insecticides for the control of insect pests. For successful insect management, EPNs must be established in the soil and remain infective, persistent and pathogenic for long pe…

Taxometrical and numerical characterization of an isolate of Steinernema abbasi (Elawad et al., 1997) with larger infective juveniles comprehensive from ITS1-5.8SITS2 region of rRNA

Istkhar, A. K. Chaubey

In present investigation Steinernema sp. isolate CS1 was identified with the aid of numerical taxonomy as an additional tool. Presence of two horn-like structures on head region of 3rd stage infective juveniles (IJs) placed the nematode in bicornutum group and…

Influence of different initial spore concentrations of Pasteuria penetrans on the infection of root-knot nematodes over three host crop cycles

D. A. Darban, S. R. Gowen, B. Pembroke, F. Hussain

The number of egg-masses, females per plant, over all the crop cycles were compared by accepting a parallel line, logarithmic model. The number of egg-masses per plant over all the crop cycles decreased significantly (P < 0.05) more in the ten females treat…

H. Ravindra, N. Adivappar, M. Sehgal3 D. M. Soumya, H. B. Narasimhamurthy

Surveys were conducted of coriander plantations from open and protected cultivations at Karnataka for the prevalence of nematode. Heavy infestation of root-knot nematode was observed on coriander with small to big sized galls or knots on the roots. Soil and ro…

Effect of sugar beet as a trap crop on the population density of Meloidogyne incognita infecting subsequent common dry bean

M. M. A. Youssef, W. M. A. El-Nagdi

Sugar beet (Beta vulgaris L.) cv. Gazelle was planted under screen house conditions to assess its ability as a trap crop to reduce population density of root-knot nematode, Meloidogyne incognita on subsequent common dry bean (Phaseolus vulgaris L.). Treatments…
