Ascaridia galli infection induced gross-pathological changes in broiler chicken

S. Feroza, A. G. Arijo, F. M. Bilqees, M. S. Phulan

In this study, the effect of Ascaridia galli infection on gross-pathological changes in broiler chicken was investigated. The postmortem examinations of broiler experimentally induced A. galli revealed gross pathological lesions of infected organs viz., small…

Population density of Meloidogyne incognita and eggplant growth vigour affected by sucrose-activated bread yeast (Saccharomyces cerevisiae)

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

Active dry bread yeast containing fungus, Saccharomyces cerevisiae was used as a bio-agent for controlling root-knot nematode, Meloidogyne incognita on eggplant under screen house conditions. Three solutions of yeast and sucrose (as a bio-fermenter) at differe…

Analysis of Arabidopsis amino acid metabolism in response to Heterodera schachtii infection

S. Anwar, K. Wieczorek, E. Inselsbacher

In the present study, a detailed amino acid analysis based on Ultra Performance Liquid Chromatography (UPLCTM) was performed. The results showed significant increase in arginine, proline and glutamine amounts in syncytia. Ammonium ions were also increased as a…

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…

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…

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…

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…

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…

Nematicidal performance of certain organic and inorganic compounds against Meloidogyne incognita infecting okra plants

A. S. A. Saad, M. B. Al-Kadi, A. A. A. Deeabes, A. M. El-Kholy

The present study was carried out to evaluate the nematicidal activity of some organic and inorganic compounds, as well as fosthiazate as a standard nematicide for their hatching inhibitory and juvenile mortality potential and to ascertain their role as organi…
