The scientific name Neoceratitis asiatica (Becker) is a diptera, fruit fly family. Alias ​​fruit, day. Minute. Clothed in Ningxia, Qinghai, Xinjiang, Tibet and Inner Mongolia.

Host 枸杞.

Characteristics of the larvae The larvae feed on the flesh, and the affected fruits show white spots, forming fruitless fruits with no economic value. Severe reductions of 22% to 55% are one of the three major pests on the pupa.

Morphological characteristics Adult body length 4.5-5mm, 8-10mm wingspan. The head is orange-yellow, white-faced, complex-eyed and emerald green, reflecting black lines like jade. Between two eyes with "Ω" pattern, 3 monocular. Mouthpiece orange. Antennae orange-yellow, brown-angled, with micro-hairs. The head needs to be complete. The back of the chest is painted black, with a strong light, the middle with two vertical white lines and two short white lines on both sides are connected to a "North" shape, with white hair. This white grain is sometimes inconspicuous. The back of the scutellum is white in wax and its circumference and back are black. The wings are transparent, with 4 dark-brown stripes, 1 along the leading edge, and the remaining 3 are obliquely extending up to the wing edge; the tip of the subfrontal vein is turned to the front edge at right angles, and the right-angled inner side has 1 small circle, according to which Similar differences. Foot yellow, claw black. The midsection of the abdomen is wide and sharp, with an inverted conical shape, with 3 white horizontal stripes on the back. The center of the front and middle strips is interrupted by a dark brown vertical pattern. The female spatula protrudes from the ventral end of the female, and the flat round looks like a duckbill; the tip of the male abdomen is pointed. Egg white, oblong. Larvae body length 5-6mm, conical, sharp front end, thick rear end. Mouth black. In front of the valve sector, six respiratory holes on the rear valve are arranged in two rows at the end.蛹 long 4-5mm, width 1.8-2mm, oval, one end, light yellow or auburn. Habits of life 2-3 generations, in order to squat in the depths of 5-10cm in the winter. In early May of the following year, adult larvae emerged at the time of bud emergence. In late May, a large number of adults were unearthed. The eggs were laid in the young pericarp. Generally, one ovum per fruit, the larvae hatched and then licked the fruit flesh. In late June, the larvae matured in early July. After that, it was drilled from the fruit and landed. In the middle and late July, two adult ecloses emerged. In late August and early September, three generations of adult worms emerged. After three generations of larvae, they quailed and wintered. Adults are mild, and when they are stationary, the wings flutter up and down.

Control methods (1) At the end of April and early May, use 5% parathion granules plus 5 times fine dry soil, mix and spread on the surface of the soil, and then dig into the soil, use 1.5-2kg per 667m2 to eliminate overwintering. And adult eclosion. (2) During the fruit-picking period, the pods are concentrated together and buried deep or concentrated on the day to prevent the larvae from escaping and spreading. (3) Infusing water and turning soil in time to kill overwintering earthworms and summer beaks in the soil will have a certain effect on lowering the density of insect populations.
