Management of green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae), in bell pepper, Capsicum annuum L., was explored through a combination of plant growth-promoting rhizobacteria (PGPR) and endemic biological control in New York in 2006 and 2007. We hypothesized that by using PGPR-treated peppers 1) M. persicae infestations would be reduced via induced resistance, 2) natural enemie...

peach (prunus persica l. batsch.) is produced in most areas of iran, where flowering is hindered by temperature. using plant growth regulators to delay bloom is a suggestive measure to avoid frost damage. the objective of this study was to determine the effects of methyl jasmonate (mj) and salicylic acid (sa) on peach bloom delay and yield.  this study evaluated the applications of mj 0 (contro...

Pecan foliage is attacked by three species of aphids [Monellia caryella (Fitch), Melanocallis caryaefoliae (Davis), and Monelliopsis pecanis Bissell], resulting in damage that can reduce tree nut yield. In this study, we assayed the ovipositional response of the green lacewing Chrysoperla rufilabris (Burmeister) to M. caryella and M. caryaefoliae at high and low aphid densities and the developm...

Two amino acid substitutions (L1014F and M918T) in the voltage-gated sodium channel confer target-site resistance to pyrethroid insecticides in the peach potato aphid, Myzus persicae. Pyrethroid-resistant and -susceptible M. persicae clones with various combinations of these mutations were crossed under laboratory conditions, and the genotypes of aphid progeny were analysed by direct DNA sequen...
