What does mole cricket eat
When farming in the field, it is often found that seedlings are inexplicably lodging and crop roots are incomplete. These abnormal phenomena are often closely related to the underground pest mole cricket. As a typical omnivorous underground pest, mole cricket's damage to crops has two major characteristics: concealment and persistence. This paper will comprehensively analyze the threat of mole cricket to plants from its feeding characteristics, harm manifestations to systematic prevention and control. Diet characteristics and feeding patterns of mole cricket crop preferences list The diet of mole cricket covers 118 species of plants from 34 families, with a special preference for gramineae crops: 1. Seedling stage: corn germ, wheat tender stem, sorghum seedling 2. Adult stage: potato tubers, sweet potato roots, peanut needles 3. Special hobbies: Breeding experiments on watermelon vine base, cabbage main root, and tobacco transplanted seedlings found that artificial breeding data showed that each adult's average daily food intake reached 150% of its own body weight, especially for crop tissue with high sugar content. When the ratio of soybean cake and wheat bran is 3:7, the egg laying quantity can be increased by 20%. The triple threat of mole crickets to plants The underground destruction mechanism was found through soil profile observation: ·Sowing period: biting the seed endosperm, resulting in a 40-60% reduction in emergence rate. Seedling period: ring-shaped gnawing on the tender stems to form "decapitated seedlings". Maturity period: Network damage to the root system causes the whole plant to wither. Economic loss assessment When there are 200 mole crickets per mu, it can cause: ·Vegetable production reduced by 35-50%. Grain weight dropped by 22%. Cash crop commodity rate reduced by 28%. Physical control plan for three-dimensional control system·Light trap: A 20W black light lamp is set up every 5 acres, which increases the capture efficiency before rain by 70%. Cure pit trap: 50cm deep pit + fresh cow dung, a 12-hour capture rate of 83%. Chemical control technology·Poison bait formula: trichlorfon: wheat bran =1:50, with the best effect at dusk·Soil treatment: Thiamethoxam granules are 3kg/mu, with a lasting effect period of 45 days. Ecological prevention and control strategy·Introduction of natural enemies: release 2000 parasitic bees per mu·Rotation system: three-year rotation of Gramineae, Legumentum and Solanaceae·Deep plowing to eliminate eggs: Deep plowing 30cm after autumn harvest and destroying the wintering nest room By establishing a four-level defense system of "monitoring and early warning-physical blocking-chemical control-ecological adjustment", the mole cricket hazard can be controlled below the economic threshold of 5%. Growers need to pay special attention to the two key windows for prevention and control: the adult migration period from April to June and the winter period from September to November.
