Feed Formulation and Processing Techniques for Medicinal Silkworm Larvae Infected with Beauveria bassiana
Currently, medicinal silkworm larvae infected with Beauveria bassiana are in strong demand on the Chinese medicinal herb market, and raising and processing them is profitable. The methods for raising and processing them are: 1. Rearing the mature silkworms. Raising and processing medicinal silkworm larvae infected with Beauveria bassiana should be carried out as a specialized operation in non-cocoon-producing areas, so as to avoid a devastating impact on cocoon silkworms. The raising and processing can be carried out throughout the year. As for the feed, besides a small amount of mulberry leaves, more evening primrose, Jiancan grass, white clover, cup plant (Silphium perfoliatum) and the like can be added to replace mulberry leaves, so as to supplement the shortage of mulberry leaves and reduce feeding costs.

Rearing Methods and Management Key Points for Male Silkworm Larvae
I. New Hybrid Male Silkworm Varieties (1) Variety characteristics. The new autumn-rearing male silkworm variety Qiuhua x Ping 30, bred by the Sericulture Research Institute of the Zhejiang Academy of Agricultural Sciences, has the advantages of a strong constitution, uniform molting and rising in each instar, and being easy to rear. The number of silkworm larvae per gram is about 2310, the 5th instar lasts 6 days and 18 hours, the whole instar lasts 22 and a half days, the two-day hatching rate is 49.34%, the silk length is about 1240 m, the cocoon shape is oval, large and uniform, the cocoon color is pure white, and the cocoon shell rate and silk yield are high. (2) Key points of rearing technology. For gathering newly hatched silkworms, light exposure can be

What pesticide gives the best control effect against older larvae of the rice leaf roller?
Chlorpyrifos and abamectin-monosultap are effective agents for controlling the rice leaf roller, but they must be applied during the 1st-2nd instar young larval stage (at this stage the rice leaf roller has not yet rolled leaves and caused damage, or has just begun rolling the leaf tips and causing damage), when the rice in the field has just begun to roll leaves. For rice leaf roller larvae of the 3rd instar and above, on the one hand they are protected because they are wrapped inside the rice leaves, and on the other hand they are insensitive to nereistoxin-type pesticides such as monosultap and to organophosphorus pesticides such as chlorpyrifos, methamidophos and monocrotophos, so the control effect after spraying is poor. Relatively speaking, older rice leaf

How can sheep bot fly larvae disease be treated effectively?
Sheep bot fly larvae disease mainly affects sheep and goats. This disease mainly occurs from early autumn to mid-autumn. After infection, the sheep become restless, showing symptoms such as shaking the head, running around, and lowering the head to press the tip of the nose against the ground; some hide their heads under the bellies of other sheep. Treatment: (1) In early autumn, when adult flies fly and deposit larvae, an insecticidal ointment can be applied to the sheep's nose and nostrils once every 7 days to prevent adult flies from depositing larvae. (2) Spray 60 ml of 3% Lysol solution into the sheep's nostrils once a day for 7 consecutive days; the curative effect is excellent.
