Relative resistance or susceptibility of maple Acer species, hybrids and cultivars to six arthropod pests of production nurseries. Laboratory experiments showed that inhibition of feeding was the main mode of action through which kaolin affected nymph populations.

You must accept the terms and conditions. Further, these systems were more efficient agronomically and economically, and were thus more profitable than a castor monocrop. Eggs of Empoasca kraemeri hatched in 8. Pygofer long, fine setae sparse, inconspicuous. Subgenital plate basal, depressed section subequal to or empoasac than distal, compressed section.

Adaptation and differentiation of temperate phylogenetic lines from tropical ancestors in Empoasca. PubMed Prado, Julia; Quesada, Carlos; Gosney, Michael; Mickelbart, Michael V; Sadof, Clifford Although leaf nitrogen N has been shown to increase the suitability of hosts to herbivorous arthropods, the responses of these pests to N fertilization on susceptible and resistant host plants are not well characterized.

I agree to the terms and conditions. Close mobile search navigation Article navigation. Nymphs were grouped into three age intervals: Drosophilidae in Northwestern United States. Insect behaviors are often influenced by light conditions including photoperiod, light intensity, and wavelength. In the last experiment, the effect of buprofezin on adults was investigated.

Quantitative PCR and in situ hybridization experiments indicated that the leafhopper Scaphoideus titanus releases Cardinium from its salivary glands during feeding on both artificial media and grapevine leaves.

PubMed Hidalgo, Eduardo; Benjamin, Tamara; Casanoves, Fernando; Sadof, Clifford Importation of live nursery plants, like Dracaena marginata Lamoureux Ruscaceaecan provide a significant pathway for the entry of foliar pests from overseas into the United States. If you originally registered with a username please use that to sign in.

Our work suggests that changes in light conditions, including photoperiod and wavelength, can influence behavioral activities of leafhoppers, potentially affecting other life history traits such as reproduction and development, and may serve as a method for leafhopper behavioral control.

Plant-mediated interspecific horizontal transmission of an intracellular symbiont in insects. Connective corsal keel present on midline posteriorly.
