How to prevent tamarisk jumps

Alticssp is a coleopteran and leaf nail pest, mainly distributed in Henan, endangering willow, dry willow, willow and other willow families. Adults and larvae can all be harmed. The first-instar larvae eat leafy flesh on the back of the leaves, leaving only the veins in a gauze-like shape, which can cause the leaves of the Tamarix to be eaten when severe.

The tamarix larvae have a body length of 4 mm to 6 mm, an oblong shape, and a deep blue metallic luster. The antennae are filiform, extending backwards to the middle of the wing sheath. Egg yellow, long oval, 0.7 mm long, 0.4 mm wide, white wax powder on the surface. The larvae are 5 mm to 7 mm in length, with fine heads and tails, black bodies, and luster. In the Gushiliu planting area in Gushi County, Henan Province, four or five generations occurred each year, and the adults were overwintering in weeds and deciduous forests.

For larvae, adults in the tree feeding on the harmful activity period, especially in the early adult tree stage, spraying 80% dichlorvos or 95% dipterex crystals 1000 to 2000 times; 2.5% fenpyrifos EC 8000 to 10000 times solution 40% omethoate EC 2000 times; 50% malathion EC or 25% imidophos EC 800 times; 20% killing enemy emulsions, each adding 7.5 kg to 10 kg, loading The sprayer was sprayed after shaking and the dosage ranged from 45 to 60 per hectare.

According to the early larvae and adults of Tamarix ramosissima, it is possible to use its artificially dead nature, artificially oscillating shoots, or removing insects, killing eggs, and burning in groups to reduce the population density.

According to the overwintering habits of adults, the combination of woodland in the winter tends to remove the weeds and defoliants on the ground and concentrate the incineration to eliminate some overwintering adults.

Protect and utilize natural enemies and implement biological control. The main natural enemies include hunting hunter thighs, long-legged green spiders, wasps, crickets and so on.
