Tips on insect pests of fruit fly orange
Bactrocera dorsalis Hendel, also known as oriental fruit fly, belongs to the fruit fly genus of Diptera fruit fly family, commonly known as citrus maggot, fruit maggot and yellow fly. The insect can harm the fruits of a variety of fruit trees (Citrus, mango, peach, pomegranate, jujube, pear, apple, etc.) and vegetables (eggplant, pepper, cucumber, tomato, etc.), and is listed as an important quarantine object in the world. After the fruit is damaged by it, it withers, shrinks and rots, forming "maggot fruit", causing a large number of fruit drop, seriously affecting the yield, and even leading to a failure of harvest. In 1992, China included it in the list of class II dangerous pests in the entry plant quarantine.

1、 Know little fruit fly orange
Morphological characteristics of the fruit fly Drosophila tangerine
Egg: spindle shaped and slightly curved, blunt and round at the tail, milky white at first delivery, and light yellow later. It is about 1 mm long and 0.1 mm wide.

Larvae: maggot shaped, with a thin head, a thick tail, a black oropharyngeal groove, a total of 11 segments, and 9-10 fingerlike processes in the anterior valve. The larval stage is divided into three instars, and the length of the first instar larva is 1.2 ~ 3.8 mm; The body length of the 2nd instar larvae is 2.5 ~ 5.8 mm; The 3rd instar larvae are 7-11.2 mm long.

Pupa: it is a peripupa, oval, about 5 mm long and 2.5 mm wide. It is light yellow at the beginning of pupation and gradually turns into reddish brown. There are residual protrusions in the front of the valve, and the valve contracts slightly after the last segment.

Adult: the female is generally slightly longer than the male. The adult is 6-8 mm long, with a wing span of 14-16 mm and a dark brown body color. There are three pairs of brown lateral lines and a central Brown original spot on the forehead. The antennae are slender. The third section is twice as long as the second section. The wings are transparent. There are brown stripes on the front edge and hip compartment. The abdomen is elliptical and flat from top to bottom.

Occurrence characteristics of the fruit fly Drosophila tangerine
There are 4-11 generations every year, overlapping generations, coexistence of various insect states in the wild, and irregular generations. In areas with high temperature in winter, damage can occur all year round without overwintering. The duration of one generation is 3-5 months.
The male adult is harmless. After mating, the female adults insert the ovipositor into the fruit to lay eggs, and then begin to damage the fruit; After hatching, the larvae eat the pulp in the fruit, causing the pulp to rot, leading to a large number of fruit drops and even no harvest.
When the adults lay eggs, they formed wounds on the surface of the fruit, causing a large amount of juice to overflow. After the wounds were healed, scars were formed on the surface of the fruit. The wound formed by egg laying is easy to cause the invasion of pathogenic microorganisms and make the fruit rot.
The adult begins to lay eggs 2-3 weeks after emergence, and the egg laying period is more than 50 days. Each female can lay 400-1800 eggs in her lifetime, with a maximum of more than 3000 eggs. The life span of adults is about 2-3 months, and the longest is 1 year.
When food is in short supply and the climate is not suitable, in order to find a suitable living environment, adults can fly for a long distance, generally 1-2 kilometers, and 46.5 kilometers at most.

Harmfulness characteristics of fruit fly, Bombyx mandarinus
The fruit fly mainly feeds on the fruit by larvae. The female adult lays her eggs under the skin of the fresh fruit, causing mechanical damage and providing conditions for the invasion of other pathogens. The eggs hatch in the fruit. The newly hatched larvae have the habit of feeding in groups. After a period of growth, they gradually shrink and become pale yellow. With the increase of age, the larva's food intake gradually increases, and it extends to the deep layer of the pulp to feed, forming a hidden path in the pulp tissue, causing most of the affected melons and fruits to rot and fall off. When the fruit is rotten, the old mature larvae emerge from the fruit and move on the ground in a bouncing manner to find a suitable place to pupate. Some old mature larvae that have not yet separated from the fruit can also pupate inside the fruit. The characteristics of the larva's lurking in the fruit make it difficult for fruit flies to detect, and it spreads with the killed melons and fruits or with the packages and transportation vehicles as pupae. When the environmental conditions introduced into the non epidemic area are suitable, it spreads and spreads rapidly, posing a serious threat to local fruits and causing economic losses.

2、 Control methods of fruit fly

(1) Qingyuan
Clean up the site where the damage of Citrus fly occurs, especially the orchard with mixed fruits and vegetables. It shall be removed once a week at the initial stage of fruit falling, once a day from the peak to the end of fruit falling, and then the fruit falling shall be concentrated in the deep earth pit, covered with soil for more than half a meter and compacted.  
 
(2) Yellow board trap
Taking advantage of the habit of the adults of the fruit fly Drosophila tangerine like to lay eggs on the yellow fruits that are about to mature, the adults can be trapped by yellow sticky plates.
  
(3) Trapping and killing adults
The sex pheromone of fruit fly Bombyx mandarinus was used to trap and kill male insects and reduce the number of insect sources in orchards.
 
(4) Chemical control
Spraying pesticides on the ground of the orchard to kill the underground larvae and unearthed adults before the adults emerge; Before the fruit matures, spray pesticides in the orchard to kill the small fruit fly in the orchard.
 
(5) Biological control
a. The protection and utilization of natural enemies, such as ants, fruit fly cocoon bees, presplitting long tube cocoon bees, Paederus, carapace beetles and Beauveria bassiana, have a certain control effect on fruit fly.  
b. The conglv fruit fly bait produced by Nanjing Xin'an Zhonglu Biotechnology Co., Ltd. can release a high concentration of attractive smell for a long time, effectively attract male and female adults of the fruit fly, effectively reduce the number of adults, and reduce the harm caused to orchards by fruit flies laying eggs.
