Ovipositional Resistance to Empoasca kraemeri (Homoptera: Cicadellidae) Phaseouts vulgaris L., to the leafhopper Empoasca kraemeri Ross and Moore. Empoasca species leafhoppers are a major insect pest of common bean, Phaseolus vulgaris that cause significant economic losses in both tropical (E. kraemeri).

Aedeagus atrium in caudoventral view not greatly expanded laterally, less than 2x average width of preatrium or shaft.

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. Successional time-course feeding experiments with S.

Middle femur with 1 dorsoapical macrochaeta. All the contents of this kraeemeri, except where otherwise noted, is licensed under a Creative Commons Attribution License. This study comparatively evaluated four field populations of E.

Disapididae, Chrysomphalus aoinidum L. Style base linear or slightly sinuate, without distinct bend at point of articulation to subgenital plate. 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.


Aedeagus postatrium absent, little if any development of atrial complex beyond emplasca of shaft.

Egg parasites Anagrus spp. The diversity created by introducing cluster bean, cowpea, black gram, or groundnut as intercrops in castor 1: Pygofer mesal sensilla field well developed, conspicuous. Subgenital plate group A basal marginal setae well differentiated longer than group B setae but not greatly thickened.

Leafhoppers, especially females, changed their behavioral patterns to a two day cycle under DD. Don’t have an account? Nomenclatural changes in Cicadellidae: Male abdominal sternite VIII without conspicuous pair of lateral setae.

Field and greenhouse studies were done to identify ovipositional antixenosis the plant property responsible for resistance in common beans, Phaseouts vulgaris L. Krafmeri Migration and Severity of Impact. Third tergal apodemes and perhaps fourth and beyond absent. At the lead optimization stage, variations at three regions of compound 1, i.

Implications for integrated pest management are discussed.

Physiological response of glandular-haired alfalfa to potato leafhopper Hemiptera: Aedeagus distal paired processes absent.

The egg-laying frequencies, that determinates insect longevity, were: The leafhopper populations in two almond witches’-broom phytoplasma AlmWB infected sites: In order to reduce the use of insecticide, the application of Beauveria bassiana may be an alternative control. Segment X base with well-sclerotized dorsal arch.


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.
