Cicada breeding: a brief introduction to cicada breeding1. Planting trees Choose healthy tree species with well-developed root systems, lush growth, and more sap, such as poplar, elm, willow, tung or various fruit trees in the orchard. You can also plant honeysuckle and day lily in the breeding area. In addition, intercrop some root and tuber plants, such as potatoes, sweet potatoes, and yams. You can build a gauze shed and use dwarf trees. The gauze should be more than twice the height of the tree, so that the cicadas can reproduce freely. When selecting seeds, male and female should be one to one. (II) Branch processing Collect the egg branches and bundle every 100 branches. Then mix it with 1% washing powder (100 kg of water to 1 kg of washing powder), and then soak the bundled branches in the solution for two minutes. After taking them out, rinse them with clean water and stand them upright to dry. After that, spray them with pot ash mixed with water to kill pests and bacteria. (III) Indoor storage First, clean the room, use dark fire and smoke to disinfect, kill insects and sterilize. Then pack or box the dried branches and place them on the indoor rack, and make the room ventilated and light-permeable. 4. Indoor incubation At the end of May in the Gregorian calendar (when the temperature is suitable), you can hatch indoors or in a greenhouse. Place 10-15 cm of dry sand in the indoor or greenhouse, or use a plastic pot in the greenhouse to fill it with 10-15 cm of dry sand. Soak the branches in 20-degree warm water for two minutes, take out 10 bundles and place them on the sand in the indoor or greenhouse. Use 0.1% glucose powder and water to spray the branches with a sprayer to supplement the nutrition of the eggs stored in the dry branches for a long time. The larvae hatched in this way are strong and have a high survival rate. Note: Spray evenly with warm water three times a day, the humidity should not drip down, the temperature should be kept at 26-32 degrees, and the hatching time is 30-35 days. (V) Planting At the end of June in the Gregorian calendar, the hatched egg branches are buried for breeding. First, loosen the forest land with a pestle, 60 cm away from the tree and 15 cm deep, to loosen the soil and avoid breaking the tree roots, so that the pests can hide in the 15 cm mature soil layer. When digging trenches for planting, the distance should be about one meter from the tree, and the trench depth should be 35 cm. Sawdust and plant ash should be sprinkled on the bottom of the trench to kill insects and sterilize. Sawdust can promote the growth of larvae. Then put the hatched branches at the bottom of the trench, seal the trench with soil, 2 cm above the ground, do not step on it, do not water it, and after a period of time, you can fertilize, water, and spray the tree. How to raise cicadas that have not shed their shellsDig a hole in soft soil, about 10 cm high and 2 cm wide. Just enough for dew to form. Sprinkle some soil around the hole. |
