1997 article

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

Johnson, M. T., Gould, F., & Kennedy, G. G. (1997, February 1). Entomologia Experimentalis Et Applicata, Vol. 82, pp. 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
topics (OpenAlex): Insect Pest Control Strategies; Insect Resistance and Genetics; Insect-Plant Interactions and Control
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 article

Interaction of Resistant Plants and Wasp Parasitoids of Tobacco Budworm (Lepidoptera: Noctuidae)

Johnson, M. T. (1997, April 1). Environmental Entomology.

By: M. Johnson n

author keywords: Heliothis virescens; Campoletis sonorensis; Cardiochiles nigriceps; Bacillus thuringiensis toxin; transgenic tobacco
topics (OpenAlex): Insect Pest Control Strategies; Insect Resistance and Genetics; Insect-Plant Interactions and Control
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 article

Interaction of Genetically Engineered Host Plant Resistance and Natural Enemies ofHeliothis virescens(Lepidoptera: Noctuidae) in Tobacco

Johnson, M. T., & Gould, F. (1992, June 1). Environmental Entomology.

By: M. Johnson n & F. Gould  n

author keywords: INSECTA; HELIOTHIS-VIRESCENS; HOST PLANT RESISTANCE; NATURAL ENEMIES
topics (OpenAlex): Insect Resistance and Genetics; Insect Pest Control Strategies; Insect and Pesticide Research
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)
