A mixture of (E,Z)-isomers of methyl 12-trishomofarnesoate (methyl 3,7,11-trimethyl-2,6,10-pentadecatrienoate), a juvenile hormone mimic, was synthesized in nine steps (32.6% overall yield) by starting from only four commercially available materials: 2-hexanone, vinylmagnesium bromide, methyl acetoacetate and trimethyl phosphonoacetate. The mimic is useful in increasing the yield of silk by elo...

the effect of fungicides on silkworm larvae was analyzed with regard to the fact that these beneficial insects are usually affected by fungicides, daily feeding on 1 and 2g/liter of carbendazim, a systemic fungicide, did not have significant effects on larval and pupal mortality. however the weight of the treated larvae showed considerable weight decrease up to 37% weight.. all the economic tra...

objective: the study was conducted to evaluate cardioprotective effect of silk cocoon (abresham) bombyx mori (b. mori) on isoprenaline-induced myocardial infarction. this study deals with the cocoons, which is called abresham in the unani system of medicine. it is one of the 64 drugs which avicenna has mentioned in avicenna’s tract on cardiac drugs and used in the treatment of cardiovascular di...

The long-arm and short-arm genes of fibroin light chain (L-chain) of silkworm, Bombyx Mori L., and the gene of human acidic fibroblast growth factor were cloned respectively and subsequently inserted into a transfer vector pVL1392 used as a tool to target the L-chain region of the silkworm genome. Genomic DNA from their offsprings was extracted and the expected targeting was detected using poly...

Kokon merupakan produk yang dihasilkan oleh ulat sutera (Bombyx mori), banyak mengandung serisin membungkus filamen pada serat fibroin kokon, bobotnya 20-30% dari bobot total kokon. Serisin ini salah satu antioksidan bermanfaat mengurangi proses aging disebabkan radikal bebas. didapatkan kokon bekualitas baik maupun cacat, diharapkan dapat diformulasi menjadi sediaan serum limbah sebagi anti-ag...

Since ancient times, honey has been considered one of the most illustrious and esteemed natural products. Honey plays two key roles; specifically, it is an appreciated nutritional product, also exhibits a wide range beneficial properties for human health as therapeutic agent. Furthermore, shown that valuable effects on biological physiological features mulberry silkworms (Bombyx mori). Bombyx m...

Sericulture or silk farming is the rearing of silkworms for the production of raw silk. The mulberry silkworm, Bombyx mori, is a domesticated and monophagous insect which feeds only on the leaves of mulberry for its nutrition. Thiadiazoles are heterocyclic compounds containing oxygen and nitrogen. 1, 3, 4, thiadiazoles are extensively studied and are known to play diverse biological activities....

the impact of pgf2? on total proteins, free amino acids and the amino transferases in the gonads of silkworm, bombyx mori l. were investigated in the present experiment. the effect of pgf2? resulted in increase in the total protein and free amino acid contents in the gonads of silkworm larvae indicating improved structural and dynamic levels of organization. the enhanced activity levels of amin...

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 commer...
