Difference Between Orange Fruit Fly and Guava Fruit Fly

Fruit flies, this kind of pests fly flexibly, the body shape is like a bee, so it is called "needle bee", also known as fruit borer, orange small fruit fly, orange big fruit fly, yellow fly, melon maggot, etc., the reproductive ability is very strong, and there is migration, chemical control is difficult to achieve the ideal effect. Because its eggs are laid in the skin of the hanging gourd through the tail needle, the egg masses are difficult to detect with the naked eye. The fruit fly has a tail needle on its tail, which is the ovipositor.

The adult worm lays eggs and pierces the melon fruit, and the hatched larvae eat the melon pulp, causing the melon and fruit to turn yellow locally, and then the whole melon (fruit) rots and smells, resulting in a large number of falling melons (fruits), even if it does not rot, the sting wound is condensed with flow gum, deformed and sagging, the melon (fruit) skin is hard, and the melon (fruit) taste is bitter and astringent, which seriously affects the quality and yield of the melon (fruit). It harms more than 200 kinds of melons, fruits and vegetables such as star fruit, guava, citrus, green dates, loquats, yellow peels, mangoes, papayas, peaches, plums, pears, bitter gourds, loofahs, melons, melons, longans, lychees, etc. 1. Larvae (maggots) 1. Adults.

The main differences between citrus fruit fly and citrus fruit fly are as follows:

1. Different forms.

citrus flies do not have bristles on their forewings, and there are no mid-bristle pairs on the shoulder plates; The fifth ventral plate of the male adult abdomen is depressed posteriorly; The needle process of the oviduct of the adult female is about ram in length and has a sharp end. Adult females have a long basal ganglia of the ovipositor, approximately the same length as the dorsal plates of segments 2-5;

Citrus fruit fly:

citrus small fruit fly head yellow or yellowish-brown, mid-face plate with 1 pair of rounded black face plates, most of the middle thorax dorsal plate black, 1 pair of yellow lateral longitudinal stripes after the slit, reaching behind the upper bristle of the inner hindwings; Scapula and dorsal blades are completely yellow. The foot is mostly yellow, the posterior tibia is usually brown to black, and the midfoot tibia is a reddish-brown tale. Abdomen brownish-yellow to rusty brown.

The anterior margin of the second dorsal plate has a black narrow longitudinal color, from the anterior edge of the third dorsal plate to the end of the abdomen. Composed of "T" shaped spots.

Citrus fruit flies:

2. The reproduction situation is different.

Citrus fruit flies occur one generation per year. Adults lay eggs in the fruit for damage, at room temperature, 2-4 days can hatch, eggs hatch into the 1st instar larvae, the larvae from the peel into the fruit to eat, to develop to the 2nd instar larvae, 3rd instar mature larvae, that is, from the harmful fruit drilled into the sand soil pupation, drilled into the sand soil about 5-10 cm deep, until the following April climate warms, pupa from the soil into adults, adults lay eggs again, hatch into larvae, larvae, pupa feathers, life cycle repeatedly, continue the existence of the species.

Citrus fruit flies occur in 3 to 5 generations per year, overwintering as pupae in areas with significant winters, while in areas with warmer winters there is no strict overwintering process, and there is also activity in winter. The life history is uneven, and all insect states often exist at the same time. Adults appear in Guangdong throughout the year, and the occurrence of large numbers in May and October is large.

3. The distribution area is different.

Citrus fruit flies are mainly distributed in Guizhou, Sichuan, Yunnan, Hunan, Hubei, Guangxi, Anhui and other domestic regions, as well as foreign regions such as India, Bhutan, Japan and Vietnam.

Citrus fruit fly is mainly distributed in Sichuan, Guangdong, Guangxi, Fujian, Hunan, Yunnan and Taiwan.

Fruit flies are also called fruit flies, melon fruit flies, orange fruit flies, and needle bees. It's annoying anyway! The melons and fruits are only green and astringent, and there are fruit flies standing on their heads!

It doesn't matter if you play, the melon fruit fly just injects "worm eggs" into the melon fruit, and when the melon fruit is about to ripen, the fly maggots inside will grow up, resulting in rotting and falling fruit, and the melon and fruit farmers will suffer heavy losses or even no harvest, but they are helpless!

Citrus fruit fly is the name of the insect, belonging to the order Diptera, Trypetid. Distributed in China, the United States, Australia, India, Pakistan, Japan, the Philippines, Indonesia, Tailing, Vietnam, etc., the larvae feed in the fruit, often make the fruit yellow before ripening, seriously affecting the yield and quality. In addition to citrus, it can still harm more than 200 kinds of fruits such as mango, guava, custard, peach, loquat ruler, etc.

Citrus fruit fly bactrocera (tetradacus) minax (enderlein) is commonly known as "citrus maggot", also known as orange giant eating fly, citrus fruit fly. The damaged fruit is called "maggot" and "citrus maggot", which is an international and domestic plant quarantine pest. Since the beginning of the 60-70s of the 20th century, the epidemic has been getting worse year by year.

Due to its large occurrence area and heavy damage loss, the fruits in the epidemic area are not allowed to be exported, which has caused huge economic losses to fruit farmers and has become the largest pest in citrus production.

Citrus flies belong to the family Drosophilidae of the order Dipteridae. It mainly harms more than 200 kinds of fruits such as guava, star fruit, loquat, peach, mango, custard, jujube, lotus mist, citrus, plum, peach, persimmon, banana, etc., which can be called "fruit killer".
