Cohorts of emerald ash borer larvae, Agrilus planipennis Fairmaire, were experimentally established in July of 2008 on healthy green ash (Fraxinus pennsylvanica) trees in two wooded plots at each of three sites near Lansing, MI, by caging gravid emerald ash borer females or placing laboratory-reared eggs on trunks (0.5-2 m above the ground) of selected trees. One plot at each site was randomly ...

This report is aimed at studying the phenomenon of mirage, using a method that is much simpler than those appeared in previous work ([12, 19]). It is divided in to three parts. In the rst part we look into the trajectory of light in an inhomogeneous medium and develop the mathematical method and equations that will be needed later. In the next part, we introduced a couple of models to simulate ...

To screen allelochemical-resistant species of the alien invasive weed Mikania micrantha, we studied the allelopathic inhibition effects of the leaf aqueous extract (LAE) of Mikania on seed germination and seedling growth of the 26 species native or naturalized in the invaded region in South China. Seed germination was more strongly negatively affected by LAE than seedling growth. Responses of s...

Fifty-one species in 27 genera of Pseudococcidae, plus one species of Rhizoecidae and one species of Putoidae have been recorded from Iran based on literature data and on the material in the collection of the Hayk Mirzayans Insect Museum, Iran. Keys to the Iranian genera and species based on adult female morphology are provided and the distribution data of each species and their host-plants are...
