Walnut is one of the most important nut crops in Iran. Because of its sexual propagation in Iran, the tree shows a high genetic diversity. In this study, the correlations between trunk cross-sectional area, scaffold cross area, crop density per trunk cross-sectional area and scaffold cross area, number of leaves and leaf area per nut, nut number to branch cross-sectional area, leaf number to br...

Corn flea beetles, Chaetocnema pulicaria, vector Erwinia stewartii (synamorph Pantoea stewartii), which causes Stewart’s bacterial wilt of corn (Zea mays) (10,11). Flea beetles introduce E. stewartii into plant tissues that are wounded during feeding. Movement of E. stewartii in the vascular system of resistant plants is restricted to within a few centimeters of flea beetle feeding wounds. The ...

Ultraviolet (UV) radiation directly regulates a multitude of herbivore life processes, in addition to indirectly affecting insect success via changes in plant chemistry and morphogenesis. Here we looked at plant and insect (aphid and whitefly) exposure to supplemental UV-A radiation in the glasshouse environment and investigated effects on insect population growth. Glasshouse grown peppers and ...

The essential oil extracted from Piper betle L. leaf using pilot plant steam distillation was tested against the adult housefly, Musca domestica, for insecticidal activity. LC50 values at the end of 24 and 48 h exposure periods were 10.3 and 8.7 mg/dm, respectively. Ceylon citronella oil (Cymbopogon nardus) used as a standard showed LC50s of 26.5 and 24.2 mg/dm for the same exposure periods. Bi...
