1997 journal article

Effects of natural enemies on relative fitness of Heliothis virescens genotypes adapted and not adapted to resistant host plants

ENTOMOLOGIA EXPERIMENTALIS ET APPLICATA, 82(2), 219–230.

By: M. Johnson n, F. Gould n  & G. Kennedy n 

author keywords: Campoletis sonorensis; Nomuraea rileyi; transgenic plants; tritrophic interactions; Bacillus thuringiensis toxin
TL;DR: This investigation of the potential of two natural enemies of Heliothis virescens (F.) (Noctuidae) to affect its rate of adaptation to tobacco containing Bacillus thuringiensis Berliner toxin focussed on the behavioral rather than physiological component of their interaction with toxic plants and natural enemies.

1997 journal article

Interaction of resistant plants and wasp parasitoids of tobacco budworm (Lepidoptera: Noctuidae).

ENVIRONMENTAL ENTOMOLOGY, 26(2), 207–214.

By: M. Johnson n

author keywords: Heliothis virescens; Campoletis sonorensis; Cardiochiles nigriceps; Bacillus thuringiensis toxin; transgenic tobacco
TL;DR: The interactions of 2 species of parasitoid wasps, their host, Heliothis virescens, and transgenic tobacco producing a low concentration of Bacillus thuringiensis Berliner toxin were investigated in field tests, contradicting previous findings of increased parasitism among larvae exposed for several days on toxic plants.

1992 journal article

INTERACTION OF GENETICALLY ENGINEERED HOST PLANT-RESISTANCE AND NATURAL ENEMIES OF HELIOTHIS-VIRESCENS (LEPIDOPTERA, NOCTUIDAE) IN TOBACCO

ENVIRONMENTAL ENTOMOLOGY, 21(3), 586–597.

By: M. Johnson n & F. Gould  n

author keywords: INSECTA; HELIOTHIS-VIRESCENS; HOST PLANT RESISTANCE; NATURAL ENEMIES
TL;DR: Interactions of Heliothis virescens (F), its natural enemies, and tobacco plants engineered to express low levels of Bacillus thuringiensis Berliner toxin were examined to examine synergism of resistance and natural enemies. (via Semantic Scholar)
