Empoasca (Empoasca) kraemeri Ross & Moore, 1957

Pygofer paired dorsolateral lobes present. Male anteclypeus flat or slightly convex.

At the lead optimization stage, variations at three regions of compound 1, i. Style preapical lobe absent. Subgenital plate dorsal margin of distal half in lateral view abruptly bent dorsad. Pygofer basal portion of ventral appendage not or only slightly broadened.

Pygofer ventral appendage without stout spurs apically. Within each species or hybrid there were cultivar differences in degree of infestation or damage by particular pests.

Subgenital plate dorsomedial lobe absent. Segment X apex densely microtrichiate ventrally. Pygofer basolateral setal group present, setae fine.

Famous oolong tea Oriental Beautywhich is manufactured by tea leaves Camellia sinensis infected with tea green leafhoppers, contains characteristic volatile monoterpenes derived from linalool. Aedeagus distal paired processes absent. It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide. Seventeen cultivars representing various Acer species and hybrids were evaluated for extent of infestation or injury by shoot and trunk borers Proteoteras aesculana, Chrysobothris femoratapotato leafhopper Empoasca fabaeJapanese beetle Popillia japonicamaple spider mite Oligonychus aceris and calico scale Eulecanium cerasorum.

The effect of the preventive applications was persistent and was associated with reduced E. Empoasca species leafhoppers are a major insect pest of common bean, Phaseolus vulgaris that cause significant economic losses in both tropical E. For Permissions, please email: Under continuous illumination continuous quartz lamp light, yellow light at iraemeri, and green light at nightthe activities of locomotion, cleaning, and searching were significantly suppressed during the night 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.

Pygofer ventral appendage in caudoventral view relatively straight through most of length, but curved mediad near apex. Face with maximum length The experiment was conducted in Ngale Research Station from February to Mayusing randomized block design, seven treatments, four replicates.

The relationship ejpoasca each predatory taxa and E. Pygofer distal lobe apex in lateral view broadly rounded. In kraeeri, all predators were found to be positively correlated with the presence of E. Predominant color of dorsum pale green or yellow with few symmetrical cream-colored markings on head and thorax. 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.
