Article Synopsis
- - In the southern U.S., winter canola has become a popular oilseed crop, facing annual infestations from three aphid species: Brevicoryne brassicae, Lipaphis erysimi, and Myzus persicae, with differing effects on predator survival.
- - Laboratory studies showed that two predator species, Hippodamia convergens and Chrysoperla carnea, didn’t prefer one aphid type over another and all three aphids were suitable for their development.
- - However, the development rates and adult weights of the predators were negatively impacted by feeding on the Brassica specialist aphids, suggesting that the plant compounds they sequester may be harmful to the predators.
This paper uses regression models to investigate the efficacy of the seat belt regulation as well as the circuit training and testing system in reducing traffic related fatalities in Singapore. The effectiveness of alcohol breathalysers was also studied. Results suggest that the seat belt regulation does not have any impact on traffic fatalities.
