Description of the insect:
Adult insects are large in size, 4-5.5 cm long. Their body is cylindrical and brown in colour. There is short, light-coloured hair on the body. The first thoracic ring is characterized by being large and solid, while the hind wings are longer to cover the body when resting, which helps the insect to fly.
Plant families on which insects feed
These insects feed on seeds below the surface of the soil, such as the seeds of cotton plants, corn, potatoes, potatoes, tomatoes, and vegetable plants, such as plants of the cucurbit family, such as watermelon. They also feed on fruits located above the surface of the soil, such as cucumbers and squash, and they feed on fruits of the leguminous family, such as beans. They also infect tubers below the surface of the soil, such as potatoes and yams. These insects can feed on Animal food, so they prey on earthworms and some of the insect larvae that they encounter in the ground, such as cutworms and cotton leafworms. However, if the size of these insects increases, their density and numbers increase, and their food decreases, they prey on some of them, and this phenomenon is called the cannibalism
When an infestation appears, the mole cricket infestations
usually appear from seed placement and the longevity of the plant, as borer insects spread in Egypt from north to south in agricultural lands, gardens, the Nile Islands, waterways, drains, and the sides of canals, where adult insects can pass through the tunnels they make beneath the surface of the soil in wet lands. These insects are highly sensitive to drought
The complete insect life cycle of the mole cricket
They make two types of tunnels. The first type they make while they are roaming and feeding. They are turbid tunnels close to the surface of the soil, with a diameter of about 1-1.5 cm. They allow insects to pass while they are roaming and feeding, while the second type is below the surface of the soil at a depth of 15 to 20 cm. These insects make this tunnel. With the aim of laying eggs and storing food or nourishment in it, the female of these insects builds a room on one side of the tunnel. This room is made of clay mixed with plant parts, with a diameter of about 15 cm. This room is called the living room, and is made by the females with the aim of laying eggs in it. The female remains guarding this room until incubation. The house until the eggs hatch, and the incubation period for the eggs reaches three weeks. Mating may occur between females and males in the spring, and the female lays about 500 eggs. When the eggs hatch and the nymphs emerge, she spends a few days inside the tunnel and then emerges searching for food. These harriers have 10 lifespans and then transform into the full-grown insect. Within a year, and the lifespan of adult insects is about a year. These insects have one generation every two years. During this period, they live inside the tunnels in the form of adult insects or insects in the winter, while in the spring they begin to be active and reach their peak of activity during the month of May.
