Efficacy of integrated microorganisms in controlling root-knot nematode Meloidogyne javanica infecting peanut plants under field conditions

Authors: Osman, Hamida Ahmed; Advisor: -; Participants: Ameen, Hoda Hussein; Mohamed, Moawad; Elkelany, Usama Samy (2020)

Compared to the untreated control, all treatments exhibited variable potential inhibitory activities against root-knot nematode M. javanica and enhanced peanut yield production. The most nematode suppressive treatment was the single treatment of Saccharomyces cerevisiae, followed by T. harzianum either singly or combined with the yeast. Moreover, data indicated that application of the combined treatment of yeast plus T. harzianum gave the best results in improving peanut production, plant growth parameters, and seed nutrient contents.

Integration of some biopesticides against potato tuber moth, Phthorimaea operculella (Zell.), during storage with reference to histopathological changes detected by a transmission electron microscope in the endocrine system

Authors: Sharaby, Aziza Mohamed Fouad; Advisor: -; Participants: Gesraha, Mohamed Ahmed; Fallatah, Sahar Ahmed Baker (2019)

The potato tuber moth (PTM), Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae), is an important pest. It attacks several cultivated solanaceous plants including potato (Solanum tubersum), tobacco (Nicotiana tabacum), eggplant (Solanum melonguene), tomato (Lycopersicom esculentum), and bell pepper (Capasicum annuum). It has also been reported to be found on several wild plant hosts of the following genera: Solanum, Datura, Nicotiana, Fabina, Hyoscyamus, Physalodes, Lycium, and Nicandra. All over the world, it is the most important insect pest in potato field and storage under subtropical warms and dry summer conditions. The larvae attack both foliage and tubers in the field a...
