چکیده
Bombyx mori is a silk-producing insect with high economic value. As an agricultural country, Indonesia has great potential for developing the natural silk industry, but problem of silkworm seeds constrains its implementation. The purebred crossing to develop hybrids one efforts overcome seed quality. study aimed obtain performance alternative races and candidates other than those already commercialized. stages rearing silkworms were carried out using Randomized Block Design, six treatments three replications. conducted were: Japanese crosses (927 x 919 927), Chinese (930 403, 403 930, 804 P208, P208 804). Crosses have advantages, especially in short life cycle, morphological stability, number eggs, percentage hatching cocoon cross 903 can be superior hybrid because, overall, it shows results on egg Keywords: , cross, races, ABSTRAK merupakan serangga penghasil sutra bernilai ekonomi tinggi. sebagai negara agraris sangat potensial untuk pengembangan persutraan alam, namun dalam pelaksanaannya terkendala permasalahan bibit ulat sutra. Salah satu usaha mengatasi kualitas adalah melalui persilangan ras murni. Tujuan penelitian mendapatkan performa dan kandidat alternatif selain yang sudah dikomersialkan. Tahapan pemeliharaan dilakukan menggunakan rancangan Rancangan Acak Kelompok, dengan 6 perlakuan 3 ulangan. Perlakuan dilakukan: Persilangan Jepang China galur dari mempunyai keunggulan terutama pada pendeknya siklus hidup, stabilitas morfologi, jumlah telur presentase penetasan sampai kokonnya. dapat menjadi hibrid unggulan dikembangkan karena secara keseluruhan menunjukkan hasil tinggi kokon. Kata kunci: persilangan, China, Jepang, kokon

Nucleopolyhedrovirus (NPV) was tested for vertical transmission in the silkworm, Bombyx mori. Fifth instar larvae were exposed to four different dosages of BmNPV (830, 1300, 1800, and 2000OBs/larva) and a dosage of about 2000OBs/larva was found suitable for obtaining infected adults. Histopathological studies revealed the infection in susceptible tissues and organs initially, and at later stage...
