There is an important relationship that S. kunkelii has with D. maidis, where its survival over the winter depends on the survival of the leafhopper. [3] This relationship may also be beneficial for D. maidis. When Dalbulus leafhoppers are infected with S. kunkelii, it has been reported that fertility and life-expectancy are diminished. [6]
Potato leafhopper (Empoasca fabae) belongs to family Cicadellidae and genus Empoasca within order Hemiptera. [1] In North America they are a serious agricultural pest. [2] Every year millions of dollars are lost from reduced crop yields and on pest management. [3] Crops that are impacted the most are potatoes, clover, beans, apples and alfalfa. [4]
The world's No. 3 corn exporting country has slashed millions of tons from its harvest projections for the current crop due to a rare plague of the insect that can carry a stunt disease that ...
Hemiptera (/ h ɛ ˈ m ɪ p t ər ə /; from Ancient Greek hemipterus 'half-winged') is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs.
Beet leafhoppers can infect about 300 plant species, including vegetable crops and weeds. Pinfold said the tiny bugs are 3.5 millimeters long and spend the winter in grasses of the foothills.
Experts argue that the leafhopper population has surged in recent months largely due to the lack of frosts during last year's Southern Hemisphere winter, which likely would have killed off the insect.
Beet leafhoppers are polyphagous generalists which means that they are able to feed on various different types of host (biology) plants. [2] The fact that these insects migrate during the spring and summer time to cultivated fields also means that they show a lot of variation in their host plant choices by season: feeding on desert weeds in the winter and feeding on cultivated fields in the ...
The usual agent is Beet Curly Top Virus (BCTV). BCTV is transmitted to from plant to plant by the beet leafhopper (Circulifer tenellus). Both the virus and the beet leafhopper have very wide host ranges. Once acquired by the leafhopper, BCTV is carried for the rest of the leafhopper's life, so long-distance spread is common.
