“…From the average consumption of dry matter caterpillars by 0.654 g/head/day there was excretion of Samia caterpillar droppings by 0.149 g/head/day so as to obtain the digestibility coefficient of caterpillar dry matter by 77.23% (Table 2). This digestibility coefficient is higher compared to the administration of jatropha leaves which is only 43,84-53.70% (Shifa et al, 2014) [13] . Other results found that the digestibility of Jatropha Jatropha leaf feed on instar 5 was 84.66-92.39% in dry weight (DW) basis [14].…”

Cassava caterpillars (Samia cynthia ricini) are a type of silk-producing caterpillar that consumes castor bean leaves, cassava leaves, and papaya leaves. A study was conducted to determine the growth characteristics of casava caterpillars (Samia cynthia ricini) fed with elephant cassava (Manihot esculenta Crantz) leaves. A total of 200 head Samia caterpillars are maintained by feeding them in the form of elephant cassava leaves. The parameters observed include body weight gain, body length, feed consumption and feed convertion ratio and feed digestibility coefficient. The results showed that the cultivation of Samia caterpillar by feeding elephant cassava leaves requires 21 days of cultivation time to form a cocoon. Samia caterpillars have a body length of 51.67 mm and a final body weight of 3.211 gram/head with an average body weight gain of 0.512 grams/head/day. Feed consumption of 0.168 grams/head/day with a FCR value of 1.344. Samia Caterpillar has 77.23% dry matter digestibility, 96.48% organic matter, 96.82% crude protein, 95.18% ether extract and 2.48% crude fiber. It can be concluded that the Samia caterpillars fed elephant cassava leaves have good growth and digestibility of nutrients, so it is very suitable to be used as an alternative feed for Samia cynthia ricini caterpillars.

“…Therefore, sericulture, an agro based labour intensive and environment friendly cottage industry, can become an efficient and effective income generating activity. The business holds a greater hope of hope at village Ethiopian citizen migrating to cities searching for jobs (Kedir et al, 2014). As a result, silk production from eri silkworm is practiced in different parts of the country especially by poor farmers as an additional income source through efficient use of family labor (Metaferia 2006).…”

Eri silkworms, Samia cynthia ricini B., is one of the silkworm races under utilization in Ethiopia. However, it has several strains with wide variation in their commercial traits and selection and utilization of best suited strains of this eri silkworm race that adapt to different agro will help to increase silk productivity and profitability. In this experiment, one Vietnamese (Eri 3.4) and three Indian (Eri-yellow, Eri-green and Eri evaluated in different locations (Melkassa, Hawassa, Wondo represents different agro-ecologies of Ethiopia. The experiment was laid out in Completely Randomized Design (CRD) in six replications. Thus, di statistical significant silkworm characteristic ranges in different locations which include egg hatchability (62.61% to 89.00%), larval duration (20.67days to 25.83 days), total life cycle duration (50.49 days to 74.00 days), single weight of larva (4.427 grams to 8.155 grams), effective rate of rearing (60.11% to 93.67%), single cocoon weight (1.848 grams to 2.903 grams), single shell weight (0.251 grams to 0.418 grams) and silk ratio (13.06 to 15.05%). However, a Vietnamese eri silkworm strain known by Eri performance compared to other strains in all the locations especially in cocoon parameters. Therefore, it is recommended for future research and development efforts on eri silkworms in Ethiopia.

The quality of feed plays an important role in the growth and development of silkworms and eventually in the economic traits of cocoons. This study was conducted to evaluate ten castors (Ricinus communis L.) genotypes and their feeding values on the rearing performance of Eri Silkworm (Samia cynthia ricini Boisduval) (Lepidoptera: Saturniidae) at Tepi, southwest Ethiopia. A total of ten castor genotypes were evaluated in a randomized complete block design (RCBD), and the suitability of castor genotypes as feed for a mixed strain of Eri-silkworm was also evaluated in a completely randomized design (CRD) under laboratory conditions. A hundred worms were used in each replication. Castor genotypes showed significant differences in fresh leaf yield. Among the castor genotypes tested, genotype 219645 recorded 439 g of ten fresh leaf yields. Results of Eri-silkworm rearing performance depict that a shorter larval period (22 days), a higher effective rate of rearing (94.54%), and a shorter life cycle (58 days) were observed in Eri-silkworm fed on leaves of the 200390 genotype, while a higher larval weight (6.16 g) was recorded in the Abaro genotype. However, higher cocoon weight (3.26 g), pupal weight (2.46 g), shell weight (0.45 g), and silk ratio (13.80%) were found in Eri-silkworms fed on leaves of genotype 219645. Hence, based on silkworm rearing performance, genotype 219645 showed relatively superior results and is recommended for future development work. Further studies should continue giving more emphasis to the multilocation study of genotype 219645 to understand its performance in the diverse growing environment.
