Egg morphology and stages of embryonic development of the glassy-winged sharpshooter (Hemiptera: Cicadellidae). The plants do not usually die, nor do the roots show any apparent symptoms.' ReferencesĪl-Wahaibi, A.K., and J.G. The growth rate of affected trees is greatly reduced and twigs and branches may wilt. Flower and fruit set occur at the same time on healthy and affected trees but fruits remain small and ripen earlier. Fruits are much smaller than normal and very firm. Affected trees show leaves with chlorotic yellow spots, recalling zinc deficiency the lower surface shows slightly raised brownish necrotic spots. The European Plant Protection Organization describes CVC symptoms as 'more obvious on 3 - 6 year-old trees and mainly on sweet orange cultivars. Once the insect has acquired the bacterium, it will be infectious for the remainder of its life. The glassy-winged sharpshooter is an efficient vector of the bacterium Xylella fastidiosa which causes several economically important diseases, including citrus variegated chlorosis (CVC), Pierce's disease, phony peach disease, plum leaf scald, and oleander leaf scorch. Yellow sticky traps are useful for monitoring the pest. Eggs are deposited within the epidermis of plant leaves and covered by a white chalk-like substance.The pointed end resembles the keel of a boat. Smooth, flattened, and cigar-shaped (elliptical) with one end more pointed than the other.Slate-colored with patches of rusty-red on the abdomen turning dark brown red eyes.Thin, threadlike, and pointed antennae, located in front of the eyes and point slightly forward at approximately a 60 degree angle.Wings are translucent, smoky-brown, and membranous with reddish veins.Large compound eyes protrude from each side of the head. Cigar-shaped or projectile-shaped with a bulbous head tapering towards the front.Face and legs are yellow-orange, and large eyes are yellow with dark speckles Dark brown with yellow dots on head and middle body segment ( thorax) the bottom of the rear-most body segment ( abdomen) is white with black markings.
