Butterfly larval host plant use in a tropical urban context: life history associations, herbivory, and landscape factors.

This study examines butterfly larval host plants, herbivory and related life history attributes within Nagpur City, India. The larval host plants of 120 butterfly species are identified and their host specificity, life form, biotope, abundance and perennation recorded; of the 126 larval host plants, most are trees (49), with fewer herbs (43), shrubs (22), climbers (7) and stem parasites (2). They include 89 wild, 23 cultivated, 11 wild/cultivated and 3 exotic plant species; 78 are perennials, 43 annuals and 5 biannuals.

A new continuous cell line from larval ovaries of silkworm, Bombyx mori.

A new continuous cell line from ovarian tissue of commercial variety "Kolar Gold" of silkworm, Bombyx mori, was established and designated as DZNU-Bm-12. The tissue was grown in MGM-448 insect cell culture medium supplemented with 10% fetal bovine serum (FBS) and 3% heat-inactivated B. mori hemolymph at 25 +/- 1 degrees C.

A new Bombyx mori larval ovarian cell line highly susceptible to nucleopolyhedrovirus.

Lepidopteran cell lines constitute the backbone for studying baculoviral biology in culturo and for baculovirus vector based recombinant protein expression systems. In the present study, we report establishment of a new continuous cell line designated as DZNU-Bm-1 from larval ovaries of the silkworm, Bombyx mori. The cells were grown in MGM-448 insect cell culture medium supplemented with 10% fetal bovine serum (FBS) and 3% heat inactivated B.
