Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), is a worldwide pest of onion, Allium cepa L. In Þeld studies on onion resistance conducted in 2007 and 2008 using 49 cultivars, 11 showedlowleafdamagebyT. tabaci. In laboratorystudies, the11cultivars, alongwith twosusceptiblechecks and four additional cultivars, were evaluated to characterize resistance to T. tabaci and to determin...

introduction: land use change, deforestation, grazing, intentional and unintentional fire and invasive pests and diseases are all the major cause of damage to the zagros forest ecosystem. the green oak leaf roller (tortrix viridana l.) is one of the important pests of zagros forests. larvae of the pest significantly damage the oak forests with feeding on leaves and buds of different species of ...

Leafminer (Liriomyza langei Frick) is a major pest that causes considerable damage to a wide variety of vegetable crops including lettuce, and resistant cultivars remain the most economic means of insect control. Eighty-four lettuce cultivars and introduction lines were grown in an insect cage with eight replications for resistance screening. Leafminer flies were released in the cage to feed on...

Field and greenhouse studies were conducted in Georgia and South Carolina to determine the tolerance and antibiosis effects of 15 St. Augustinegrass genotypes against the southern chinch bug. ‘Floratam’ and ‘Floralawn’ cultivars were highly resistant to southern chinch bug populations in Georgia and South Carolina. When southern chinch bugs were caged on Floratam for 37 days in a greenhouse stu...
