Eurocania ocellus, a genus of homoptera, is a family of waxhoppers.
【Host】Citrus and other fruit trees.
[Harmful] Adult and nymphs suck tender branches and sprout juice, which can also cause soot disease. Adults lay eggs in the branches of the year, affecting the growth of the branches, and in severe cases, they die above the spawning part.
【Morphological characteristics】 Adult insects have a wingspan of 15 to 16 mm, the body color is brown or yellowish brown, the wings are partially hollow, and there is an eye-like black stripe in the center of each wing, the wing veins are clear, and the wings are curved when resting. Nymphs have wax filaments on their tails, which disappear as they grow.
【Life habits】Occurs once a year, and occurs more often from June to August.
【Control method】Refer to the fourth section of the first chapter for the control of wax cicadas. (1) Loosen the soil before the cicada feathers, turn out the pupa chamber to remove the nymphs. The trunk is bandaged with a plastic film 8 to 10 cm wide to prevent the old nymphs from molting along the trunk and molting and feathering. The use of adult insects have the habit of tending to fire, in the peak of adult insect occurrence at night to raise torches in the adult insects concentrated in the place of habitat, interfere with adult insects, frightened adults will fly to the fire, wings are burned out can not fly, it will be picked up and concentrated processing. The spawning branches are cut off and burned in time before the leaves wither and fall off. (2) During the peak of feathering, sprinkle poisonous soil prepared with 40% octyl thiophosphorus emulsion on the orchard ground, or spread 50% insect powder to kill the nymph. (3) During the peak of adult insects, spraying to kill adult insects. Optional agents: 50% octathion emulsion 1000 ~ 1200 times liquid, 40% chlorpyrifos emulsion 1000 ~ 1200 times liquid, 4.5% high efficiency cypermethrin emulsion 1000 ~ 1500 times liquid, 2.5% cypermethrin (enemy killing) emulsion or 2.5% high efficiency cypermethrin (kung fu) emulsion 1000 ~ 1500 times liquid.
