Fruit fly
The fruit fly is one of the two-winged insects, and it is one of the agricultural pests, as it parasitizes on fruit trees, causing them a lot of damage, and thus weakening their productivity. The female of this fly lays her eggs inside a hole located under the peel of the fruit, and when they hatch From these eggs, yellowish-white larvae emerge, and they feed on the pulp of the fruit, and thus the fruit weakens and falls from its mother. When these larvae grow somewhat and enter the pupal stage, they emerge from the fruit and enter the soil three centimeters from the soil surface, but the depth of the presence of the pupa depends. On soil type and moisture.
Methods of control of fruit flies
The fruit fly makes the fruit an easy prey for fungi, thus reducing the productivity and quality of the fruits produced by the tree. However, to protect the agricultural crop from damage, there is a set of rules and methods that completely eliminate this bad fly.
Traps
There are several types of traps that are effective in getting rid of fruit flies. The traps are:
- Jackson's Trap: It is a pyramid made of cardboard coated with a waxy substance. This pyramid is mounted on a base coated with a very strong adhesive, and the base is also made of cardboard.
