The black-spotted moth is also known as the black-spotted leaf moth and the apple black-wing moth, belonging to Insecta, Lepidoptera, and Moth. ?
The morphological characteristics of adult body length 5 ~ 6mm, wingspan 16mm, the whole taupe. The back and front wings of the chest are dark brown and shiny. The forewings have a light-colored lateral band near the outer line at 1/4. They traverse from the leading edge to the trailing edge. There are 3 to 4 dark spots in the center of the wings, of which 2 are very obvious. After wings grayish brown. ?
Egg oval, pale yellow, about 0.5mm long, pearl luster. ?
The larvae have a body length of 10 to 15 mm and three purplish-red vertical stripes on each side of the dorsal line, which resemble vertical stripes of yellow and white and purple and red. The head, buttocks and buttocks were brown, and the chest shield was dark brown with 34 to 38 pairs of bi-sequential rings on the toe-to-hook hooks; the hips had toe hooks with 28 to 32 double-rings. ?
The larva is characterized by its larvae, which have silky leaves on the new shoots as nests with a white, slender, silky channel with feces and loose insects. Larvae are harmed by clusters in the larvae. Excessive management of young orchards occurs more severely. In severe cases, the branches and leaves of the entire tree are damaged, leaving only the veins and epidermis. The whole tree appears yellow and causes secondary leaves, affecting the growth and development of fruit trees. ?
Life history and habits occur in Hebei, Shaanxi and other provinces for 3 generations. Weeding under weeds, fallen leaves and clods. In the middle and late April of the Guanzhong area of ​​Shaanxi province, the adults of the overwintering eclosion began to spawn, spawning at the base of the young leaves that are not stretched at the top of the new shoots, and piled on a single grain or a few grains. First-generation larvae began to occur in mid-April. Young larvae are lurking on unstretched young leaves. When the larvae grow up, several leaves are rolled into insects, and the insects in the house are harmed. Only the leaves are eaten and the lower surface is not eaten. When there is a large amount of time, there are 10 to 20 larvae in one insect infestation and the leaves are damaged into gauze. In late May, the insects in the damaged leafhoppers began to metabolize; the first generation of adults emerged in late June. The second generation larvae appeared in early July. In late July, larvae were released, and second-generation adults began to emerge in mid-August. The third-generation larvae are about to harm until the middle of September, the second to the late October, and the old crops are overwintering. ?
Prevention and control methods: Artificial control: cleaning the fallen leaves in the orchard, eradicating the weeds, and eliminating the overwintering earthworms; removing the leaf curls in the growing season to eliminate the larvae; chemical control: the overwintering larvae during the flood season and the first-generation hatching During the critical period of the drug, 80% of dichlorvos EC or 48% LS, 25% quinophosphate, 50% chlorpyrifos, 50% malathion EC 1000x; 2.5% kung fu, or 2.5% enemy kill Dead emulsifiable concentrate or 20% extinction diclofenac 3000 ~ 3500 times, 10% Uranus EC 4000 times or 52.25% farmland emulsifiable concentrate 1500 times. As well as other pyrethroid insecticides, or inulin and organic phosphorus compounds.
The Silicone Adjuvant is wetting and Penetrating Agent for the agrochemical.
Chemical name: Polyalkyleneoxide Modified Heptamethyltrisiloxane
Silicone adjuvant is a super-spreading surfactant based on a trisiloxane ethoxylate.
Spray Adjuvant lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants.
And,Silicone Surfactant promotes rapid uptake of agrochemicals into plants via stomatal infiltration.
spray adjuvant is nonionic in nature, making it useful with a broad range of agrochemical formulations.
