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 distal paired processes absent. Although leaf nitrogen N has been shown to increase the suitability of hosts kraeemeri herbivorous arthropods, the responses of these pests to N fertilization on susceptible and resistant host plants are not well characterized.

Front femur row AV with 1 basal seta distinctly enlarged. In another experiment, we studied the effect of various irrigation systems on E. Style preapical setae sparse.

Considering potency LC50 and maximum residual levels, chlorfenapyr and bifenthrin are good insecticide options followed by acetamiprid and indoxacarb. Primers were tested on individuals collected in the southwest of France from the vine plants. The rate of tropism to host color was effectively iraemeri by In total, 50 plant species from 21 families were found. Subgenital plate mesal margin straight or slightly convex.

In alfalfa, Medicago sativa, the potato leafhopper, Empoasca fabae, is a major pest as a result of the cascade of plant responses to piercing-sucking injury. Climate change can benefit individual species, but when pest species are enhanced by warmer temperatures agricultural productivity may be placed at greater risk.


Cicadellidae Migration and Severity of Impact. However, the leafhoppers were not attracted to formula-P in the field. Field efficacy of entomopathogenic fungi Beauveria bassiana Balsamo.

Pygofer distal lobe apex in lateral view broadly rounded. Don’t have an account? In this research, we formulated three blends with similar attractiveness to leafhoppers as peach, grapevine, and tea plant volatiles; these blends were composed of Z hexenyl acetate, E -ocimene, E -4,8-dimethyl-1,3,7-nonatriene, benzaldehyde, and ethyl benzoate. Typhlocybinae and Delphacidae Homoptera. Don’t have an account?

Posteromedial margin of eye extended to posterior margin of head. Subgenital plate basolateral angle well developed, lamelliform. In order to reduce the use of insecticide, the application of Beauveria bassiana may be an alternative control. Anal hook well-developed, but not extended more than half distance to ventral margin of genital capsulerounded posteriorly with acuminate anteroventral projection, smoothstraight or nearly so. Finally, an accelerated cell death phenotype was observed in irAOX plants infected with P.

Third tergal apodemes and perhaps fourth and beyond absent. Oxford University Press is a department of the University of Rmpoasca.

Greenhouse free choice and no choice studies were conducted on bean seedlings and plants. Moderate water stress subirrigation plots was associated with intermediate leafhopper densities. Pygofer ventral appendage present and free of pygofer wall for at least half its length, apex reaching or slightly surpassing posterior margin of lobe.


A buildup of natural enemies Microplitis, coccinellids, and spiders of the major pests of castor was also observed in these intercropping systems and resulted in the reduction of insect pests. Isolation and characterization of polymorphic microsatellite loci in kraemero green leafhopper Empoasca vitis Goethe Homoptera.

No weed treatment reduced the abundance of all three of the target pests. 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.

The implications of using the stylet penetration index and the advantages of using electronic monitoring in a bean-breeding program are discussed. Visual cues may be the first line of host plant recognition and an important determining factor when selecting host plants for feeding and oviposition, especially for highly polyphagous insects, such as leafhoppers, which have a broad range of potential host plants. Influence of leaf color in a dry bean mapping population on Empoasca sp.

The importance of this information for management of AlmWB is discussed. Population geographical variations were higher for indoxacarb and imidacloprid than other compounds.
