Liriomyza huidobrensis (Blanchard) is an economically important and highly polyphagous worldwide pest. To establish a temperature-dependent phenology model, essential for understanding the development and growth of the pest population under a variety of climates and as part of a pest risk analysis, L. huidobrensis life-table data were collected under laboratory conditions at seven constant temp...

Cruciferous crops on Guam are infested by cabbage webworm, Hellula undalis (F.), cabbage cluster caterpillar, Crocidolomia pavonana Zeller, mustard aphid, Lipaphis erysimi (Davis), armyworm, Spodoptera litura (F.), flea hopper, Halticus tibialis (Reuter), fire ant, Solenopsis geminata (F.), leaf miners, Liriomyza spp., diamondback moth, Plutella xylostella (L.), corn earworm, Helicoverpa armige...

Two natural enemy species are frequently released simultaneously to control one pest species in augmentative biological control in greenhouses. Intraguild predation (IGP) and interspecific competition between natural enemies might affect the biological control. IGP occurs between two parasitoids, between one parasitoid and one predator, and between two predators. Although unidirectional IGP has...

Liriomyza trifolii is a highly-invasive leafmining insect that causes significant damage to vegetables and horticultural crops worldwide. Relatively few studies have quantified gene expression in L. trifolii using real-time quantitative PCR (RT-qPCR), which is a reliable and sensitive technique for measuring gene expression. RT-qPCR requires the selection of reference genes to normalize gene ex...

Eight species of the genus Cercospora from different localities in Northern provinces of Iran were obtained and examined during spring-autumn 2010. Cercospora acnidae (from Amaranthus chlorostachys var. chlorostachys), C. beticola (from Beta vulgaris), C. iridis (from Iris sp.), C. lactucae-sativae (from Lactuca sativa), C. mercurialis (from Mercurialis annua), C. sorghi (from Sorghum halepense...
