![]() We conclude that the genetic system that conditions high 2-tridecanone concentration (i.e., at least three recessive genes) is the same genetic system responsible for the high level of M. Tomato Hornworms are really big green alien-like caterpillars that can munch through and devastate your vegetable garden. Type VI trichome density, however, did account for a significant, although small, amount of the total variation in resistance in several of the segregating populations. Multiple linear regression analysis indicated that 2-tridecanone is principally responsible for the high degree of M. Briefly, upon receiving hornworm eggs, the eggs were allowed 1-3 days at 25 C on a 12:12 light-dark cycle to hatch before being randomly distributed into control (wheat germ-based artificial. Polynomial regression analysis showed that there is a semilogarithmic relationship between 2-tridecanone concentration and resistance ratings. No associations were found between type VI trichome morphology and the variables 2-tridecanone, type VI trichome density, and tobacco hornworm resistance. sexta resitance is conditioned by at least thre erecessive genes high 2-tridecanone concentration was found to be inherited in a similar manner. Results of genetic analyses suggest that M. ![]() Additionally, plants in the cross A populations were scored for morphological traits of the type VI trichome. ![]() Simply select your manager software from the list below and. you can download article citation data to the citation manager of your choice.

Manduca sexta Official Gene Set v2.0 Manduca sexta, known as the tobacco hornworm or Carolina sphinx moth, is a lepidopteran insect that is used extensively as a model system for research in insect biochemistry, physiology, neurobiology, development, and immunity. sexta resistance, assayed for 2-tridecanone concentration using gas chromatography, and evaluated for density of the type VI trichome. Identification of an allatostatin from the tobacco hornworm Manduca sexta. Excised leaflets from individual plants of the parental, F1, F2, and backcross populations of each cross were bioassayed for M. glabratum PI 134417 was crossed with the susceptible tomato (L. Download RIS Download BibTeX Arsenate of lead as an insecticide against the tobacco hornworms. Experiments were developed to study the mechanism and genetic nature of the tobacco hornworm ( resistance factor in the wild tomato (Lycopersicon hirsutum f.
