Description

Technical Field

[0001] The utility model relates to a fruit fly larvae breeding device. Background Art

[0002] Fruit flies, belonging to the family Tephritidae of the order Diptera, are widely distributed in most biogeographic regions except extreme deserts and polar regions. They mainly feed on plant secretions, nectar, fruits, sap, honeydew, bird droppings and microorganisms.

[0003] Fruit flies' utilization of their hosts depends on the host's attractiveness to adults, the host's texture, and the larvae's adaptation to survive and develop under the specific nutritional conditions provided by the host. With respect to their host plants, most fruit fly species are polyphagous, a few are oligophagous, and a very small number are monophagous. Adults of the predominantly polyphagous species have high mobility, relatively long lifespans, and high fecundity. Larvae in the second and third instars feed voraciously, eroding the host's tissues to form a gullet that transforms the host's tissue into a spongy, semi-liquid, foul-smelling substance. Female adults use their ovipositors to pierce the host's epidermis and lay eggs there, causing direct damage. During egg-laying, they also introduce intestinal bacteria, which they pass on to their offspring, into the host. These bacteria hydrolyze fruit tissue, providing the larvae with protein, amino acids, and other growth factors necessary for growth and development, while also causing secondary damage by causing the host's tissue to rot.

[0004] The South Asian fruit fly is a herbivorous insect whose larvae are cryptic and can infest all parts of its host. This insect has a wide host range, strong reproductive capacity, and excellent adaptability. It commonly hosts various fruits and vegetables in the Cucurbitaceae family, such as pumpkin, loofah, and monk fruit; as well as fruits from other families, such as guava, jackfruit, passion fruit, sapodilla, mulberry, apple, eggplant, tomato, carambola, pepper, bean, mango, and peach. Female adults of the South Asian fruit fly pierce the fruit peel and deeply into the pulp to lay eggs, often in clusters, a method similar to other fruit fly pests. After hatching, the larvae feed on the fruit flesh, causing the fruit's skin to rot and turn brown and black. Severely damaged fruit is often completely devoured, rotted, and dropped, losing its economic value. Less severely damaged fruit suffers stunted growth and deformities, affecting its quality and economic value. The South Asian fruit fly is very active during its larval stage and causes severe damage. The larvae begin to move very soon after hatching, feeding on the inside of fruits and vegetables day and night. The third-instar larvae have the largest appetite and cause the most serious damage. Therefore, many countries and regions have listed them as key quarantine targets.

[0005] In order to meet the continuous demand for fruit fly sources in the experiment all year round, efficient and large-scale indoor breeding of fruit flies has become a basic and important task. Common problems in daily indoor fruit fly breeding mainly focus on the fact that the survival of larvae is easily affected by factors such as light and humidity. Taking humidity as an example, low humidity in the breeding microenvironment is not conducive to the hatching of fruit fly eggs and the feeding of larvae, while excessive humidity is not conducive to the survival of fruit fly eggs and larvae. How to create a microenvironment suitable for fruit fly breeding is extremely important, so the research and development of a fruit fly breeding device suitable for the above conditions is the first priority. Based on the above needs and the actual problems existing in the fruit fly breeding process, the targeted design and development of this utility model patent can not only effectively solve the problems encountered in indoor fruit fly breeding, but also improve breeding efficiency.
