TL;DR: Four species of Diptera and 12 species of Hymenoptera were recorded as parasites and evidence was obtained that at least 19 species of insect, five species of spider and house mice were predators of Heliothis spp.
Abstract: Four species of Diptera and 12 species of Hymenoptera were recorded as parasites and evidence was obtained that at least 19 species of insect, five species of spider and house mice were predators of Heliothis spp. A further 12 species of predaceous insect and three species of spider were also common in unsprayed cotton. Data are presented on consumption of Heliothis eggs and small larvae by various insects and spiders in petri dishes.

04 Sep 1989TL;DR: A plant cell transformed with all or part of a Bacillus thuringiensis gene coding for either a 130 or 132 kDa protoxin against Lepidoptera, preferably with a part of the gene coding just for the respective 62 or 60 kDa trypsindigestion product of the protoxin this article.
Abstract: A plant cell transformed with all or part of a Bacillus thuringiensis gene coding for either a 130 or 132 kDa protoxin against Lepidoptera, preferably with a part of the gene coding just for the respective 62 or 60 kDa trypsin-digestion product of the protoxin. A plant, regenerated from the transformed cell, is resistant to Lepidoptera.

TL;DR: Several plant species received heavy use and appeared to be important to Lepidoptera in this urban environment, particularly butterfly-bush (Buddleia davidii), mugwort (Artemisia vulgaris), knapweed, and clover (Trifolium spp.).
Abstract: We examined the relationships among Lepidopteran species richness and relative abundance, field and park size, and herbaceous plant richness and cover in parks of New York, NY. Lepidopteran populations and habitats were quantified from 1 June–30 September 2002 in fields of 8 New York City (NYC) parks. We observed 42 species of Lepidoptera, with park size, field size, and plant species richness positively related to Lepidopteran abundance and species richness. Several plant species received heavy use and appeared to be important to Lepidoptera in this urban environment, particularly butterfly-bush (Buddleia davidii), mugwort (Artemisia vulgaris), knapweed (Centaurea maculosa), and clover (Trifolium spp.).

TL;DR: Within-plant distribution of Heliothis spp.
Abstract: Within-plant distribution of Heliothis spp. eggs and larvae on cotton was studied in North Carolina from 1980 through 1983. Egg distribution varied from year to year, with either leaves or terminals being the most common oviposition sites. Larvae were most commonly found on bolls, but were found in disproportionately large numbers on flowers and small bolls with dried flower corollas on them. The preference for flowers was less distinct for larvae of H. virescens than for H. zea larvae.
