Abstract
The research team investigated and analyzed the data of <i>Yuexi</i> silkworm rearing area in Guangdong province. Recently, the silkworm rearing farmers averagely got products from mulberry fields by 3547.65kg cocoons per hectare; the incomes rose to ¥73,363.8 (RMB) every hectare per year; for individual, the average income rose to ¥118,02.2 every year. In the five counties of <i>Yuexi</i> silkworm rearing area, the farmers in <i>Huazhou</i> input the least investment so that got higher silkworm diseases but they gained the best ratio of output and input as 365~376%; whereas that in <i>Luoding, Yun’an</i> and <i>Suixi</i> county, the number was 289.1~395%, 231.1~263% and 206.2~255.8%, respectively. However, in <i>Gaozhou</i> county, the farmers invested much more than the other counties which resulted in the lowest lost by silkworm diseases, unfortunately their ratio of output and input was low to 151~164%. Accompanied by the cost rising of agricultural materials and investments, silkworm rearing total cost increased by 16.54% and it cost ¥1,855 every household. The average productive cost account for 46.4% of income. The paper analyzed the situation in Yuexi silkworm rearing area faced, and proposed technical devices to further improve economic effectiveness with low ratio of productive cost which aims to promote quick and stable development of sericultural production.
Highlights
Sericulture is a traditional production in China with a long history which is more than five thousand years

Summary
Sericulture is a traditional production in China with a long history which is more than five thousand years. Sericulture in Guangdong province carried over no less than two thousand years and became one of the four largest silkworms rearing areas of China in 1990s. It is still one of the characteristic and traditional agricultural industry in Guangdong and form special features of tropic and subtropics in production pattern, industry model and technological level [1]. In 2010, Guangdong province planted 38,800 hectares’ mulberry and produce 79,080 tons of fresh cocoon with ¥30.62 per kilogram and sold out 1,168,566.4 boxes of silkworm eggs [4]. In 2015, the mulberry field shrink to 28,000 hectares. 800,000 boxes of silkworm eggs were delivered to the farmers which produced 57,100 tons of fresh cocoons (unpublished data)
