Ahmed S.M.H. EL Roby

The objective of this study was to study the efficacy of four indigenous and one exotic isolated entomopathogenic nematodes (EPNs) against sugarcane mealybug Saccharococcus sacchari under laboratory conditions (27 ± 2 °C, RH 65 ± 10%). The EP…

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…

Impact of nematode infestation on nutritional quality of some underground vegetables in Pakistan

M. Israr, F. Shahina, M. Habib

During the present investigation the nutritional quality of underground vegetables infected by root-knot nematode (Meloidogyne incognita) was evaluated. It was observed that physiological and biochemical changes occurred due to the invasion of root-knot nemato…

Effect of Mermis spp. infection on the fecundity of insect pests of grasshoppers

S. Riffat, S. Kumar, A. Soomro

Grasshoppers are subjected to attack by a wide range of predators and parasites at all stages of their life cycle. Fecundity of these predators and parasites of the insects was affected when grasshoppers were contaminated with Mermis spp. Mostly, the females l…

Bio-control potential of Bacillus isolates against cereal cyst nematode (Heterodera avenae)

S. Ahmed, Q. Liu, H. Jian

The effects of twenty Bacillus isolates were investigated in vitro on the second stage juveniles of cereal cyst nematode, Heterodera avenae. The isolate XZ33-3 showed significant results against juveniles (J2s) mortality followed by the isolate of XZ 17-1, XZ…

Comparison of development of Globodera rostochiensis in four potato cultivars

S. Fatemy, H. Ghasemi

Developmental stages of juveniles of G. rostochiensis Ro1 were studied in the susceptible cv. Marfona and in the resistant cvs Agria, Satina and Banba in glass-house conditions. The hatching response of the nematodes to root diffusates of these cvs was also in…

Pathogenicity and control of Meloidogyne incognita on rice in Egypt

I.K.A. Ibrahim, Z. A. Handoo

The pathogenicity of root-knot nematode Meloidogyne incognita race 1(Mi1) and race 3 (Mi3) on rice (Oryza sativa L.) was studied in the greenhouse. Seventeen rice cultivars were tested for resistance to Mi1 and Mi3. The results showed that rice cvs Araby, Giza…
