Title
The biology and behavior of the longhorned beetle, Dectes texanus on sunflower and soybean
J. P. Michaud; Angela K. Grant; J. P. Michaud; et al. Journal of Insect Science 2005. doi:10.1673/1536-2442(2005)5[1:tbabot]2.0.co;2
Other claims from this paper (15)
- Observation Reciprocal crosses of D. texanus from the two host plants all produced viable progeny on sunflower.
- Intervention effect Pupae from soybean stalks weighed about 40% less than pupae from sunflower.
- Intervention effect Adults fed on soybean lived a mean of 23 days, lower than the 53 days of sunflower-fed males.
- Intervention effect Adults fed on soybean lived a mean of 23 days, lower than the 76 days of sunflower-fed females.
- Intervention effect The female larval host plant had no effect on the tendency to ovipuncture plants in a greenhouse trial.
- Observation A field-tested population collected from sunflower contained three types of females in similar proportions: laying on sunflower only, on soybean only, or on both.
- Intervention effect In field trials, females fed more on the plant they had fed on in the laboratory.
- Intervention effect Soybean-fed females fed more on soybean in field trials than sunflower-fed females did.
- Intervention effect Females fed soybean made more ovipunctures on soybean plants in field trials than sunflower-fed females.
- Intervention effect Females fed soybean responded to sunflower plants similarly to sunflower-fed females.
- Intervention effect Females encountering sunflower first in the field showed higher total ovipositional activity than when they encountered soybean first.
- Intervention effect Females encountering soybean first showed lower total activity than when they encountered sunflower first.
- Association Feeding scores were significantly correlated with ovipunctures and eggs on both host plant types.
- Observation Relatively high fitness costs are still associated with use of soybean as a novel host.
- Observation D. texanus is still in the initial stages of a host range expansion onto soybean.
