Artificial rearing of oil gourds (bugs)
The oil gourd is a species of earthworm, belonging to the order Orthoptera. It is larger in size and about 2.5 cm in length. Inhabiting in the grass, nocturnal, males roar. Often eat melons and beans, and sometimes other insects. It is one of the favorite live foods for many ornamental birds. Especially during the bird's moulting period, if several oil gourds are fed daily, it can accelerate the growth of new feathers and make the feathers pure and shiny. In addition, because the male oil gourd singing voice is very good, but also many songbirds need to impersonate the object, but also can be good-quality males in small calabash gourds and small mud pots and other containers, lying in the arms or Putting on the bedside to listen to the cry is another tune for the songbird.
Artificially raising the oil gourd first needs to prepare a glass jar for rectangular fish farming. The size of the cylinder is not limited. Large cylinders can be bred, and small cylinders can be bred. Then use cardboard or plywood as a cover, and be tight and tightly closed to prevent the larvae from jumping into the lid after hatching. A small square hole should be opened above the lid and a window screen be nailed to allow air to flow. Prepare some sieved fine sand and scald the sand with boiling water or fry it in a pan, cool it and wait. Find several bamboo rafts with an inner diameter of 1.5-2 cm, avoiding the small sections that are 5 cm long. Put each section up and split it in half from the middle of the end. It is a long tile, and it is dried with boiling water. Find a few glass cans and wash them.
After the above-mentioned utensils are fully prepared, it is possible to begin breeding and breeding of oil gourds. After the beginning of the fall, catch a few sturdy, female belly bulges (the bigger the better) from the wild. Put sand in the can and spread it in the bottle. The thickness is about 4 centimeters. Spray a little cool water. Then put the selected female oil gourd into the bottle and place only one bottle per bottle (an additional male is also available). Pay attention to the female oil gourd, do not break or bruise the long needle ovary. Feed soy beans and Chinese cabbage hearts that are soaked in water every day. The food should be changed frequently and kept fresh. Put the bottle in a dark place and after 2 to 3 weeks of female oil gourd, insert the ovulation tube into the sand to ovulate. Whether the oil gourd has ovulated or not, see if its belly is greatly reduced. If you find that you have ovulated, remove the cucurbit in time, pour out the sand and pick out the eggs for screening. The eggs of Ophiopogon are oval-shaped, gray-gray, translucent, about 2.5 mm in length, 0.5 mm in diameter, and slightly pointed at the tip of the drum. When screening eggs, if you find yellow or white, pick it out and throw it away. Because this is an unfertilized egg, commonly known as “waterâ€, it cannot be hatched into larvae. Then remove the fish tank and wash it clean. Spread the sand in the cylinder, the thickness is about 4 cm, and the eggs are scattered about 2 cm deep in the sand. . Dip a little clear water and discharge the bamboo tile face down. The distance between the row and the row (ie between the top of the bamboo tile and the top of the other row of bamboo tiles) is 2 to 3 cm. Then lay a layer on top of each row of bamboo tiles. The role of bamboo shingles is to hide the larvae during its growth. After the bamboo tile has been placed, cover it and place it on the sunny side. In winter, the culture tank should be placed near the fire or on the radiator, and the temperature should be kept between 25 and 30°C. If the heating is too hot, the bottom of the cylinder can be insulated with wood. Every 3 to 5 days to micro-Lin: times warm water. It takes about 30 to 50 days for the eggs to emerge from the larvae. If the thermostat in the cylinder is kept at a constant temperature, the larvae can be unearthed in less than a month.
Oyster larvae look like black ants when they are burrowed out of the soil surface, and there is a distinct white pattern on the neck. At this time, the heart of the cabbage can be fed, and the larvae grow up with the hull several times under the bamboo tile. Can feed some fruits and soaked beans and the like. The oil cucurbit was unearthed from the larvae to the adult, and shells were weighed three times in the middle. As long as there are bamboo tiles in the culture tank, food is sufficient, and adult larvae generally get along with each other. The larvae in the tank can not be kept mostly, and most of them will affect the development. Always keep the food fresh and keep the sand moist and cover the light. After the adult period, the remaining strong females and males of the feeding birds are paired and placed in a can bottle to be separately raised. After ovulation, breeding is continued by the above method.
