Effect of Rearing Temperature and Humidity on Fecundity and Fertility of Silkworm, Bombyx mori L. (Lepidoptera: Bombycidae)
The effect of temperature and humidity fluctuations on fecundity and fertility of the silkworm lines was investigated during autumn and spring by exposing 4 and 5 instar larvae of eleven inbred silkworm lines ( M101, M-103, M-104, M-107, Pak-1, Pak-2, Pak-3, Pak-4, PFI-1, PFI-2 and S-1) to 25±1°C, 30±1°C and 35±1°C in combination with 55, 65 and 75% relative humidity (RH) for 3hr daily. Tempera...
متن کاملVertical transmission of nucleopolyhedrovirus in the silkworm, Bombyx mori L.
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...
متن کاملCharacterization of Klebsiella granulomatis pathogenic to silkworm, Bombyx mori L.
Bacterial disease of silkworm causes significant reduction of silk production leading to huge economic loss. This study aims to isolate bacteria from diseased silkworm and to determine its pathogenicity and antibiotic resistance. A strain of Klebsiella granulomatis has been isolated from silkworm haemolymph which was later identified on the basis of biochemical tests and 16S rRNA gene sequencin...
متن کاملRole of Food Additives on Young Age Silkworm (Bombyxmori .L) Rearing
The overall development of silkworm larvae depends on getting the required food which can be easily digested and assimilated in the body tissues properly for the silk synthesis. Keeping this in view, an attempt has been made to increase the growth of young silkworm Bombyx mori. This is ensured through supplementation of food additives, intern biochemical constituents of worm. The results of the...
متن کاملEFFECT OF BLUE GREEN MICRO ALGAE (SPIRULINA) ON COCOON QUANTITATIVE PARAMETERS OF SILKWORM (Bombyx mori L.)
Spirulina is blue-green micro algae. It contains 18 amino acids and vital vitamins like biotin, tocopherol, thiamine, riboflavin, niacin, folic acid, pyrodozoic acid, beta-carotene and vitamin B12 etc. These nutrients which are very easy to digest protein (biliprotein), carbohydrates (mucopolysaccharides, rhamnose and glycogen), 50 different minerals and trace minerals, beta-carotene, chlorophy...
