A biologically-active pest deterrent: what is the mode-of-action and how does this affect pest behaviour?
… were performed to determine the insecticidal and antifeedant properties of the product on Spodoptera littoralis, when presented with treated semi-artificial wheatgerm-based diet cubes, Triticum aestivum leaves, and Brassica napus ssp. Pabularia leaves. Additionally, the ability of the Ca2+ ion …

Synthesis of the bicyclic core of pyrrolizidine alkaloids
… addition, some of these compounds exhibit insect antifeedant activity, and so have potential applications in the agricultural industry for the protection of crops.</p> <p>For these reasons, we were interested in developing a method to form the bicyclic alkaloid core that could be functionalized to …

Species survey, monitoring and management of economically important stink bug species in eastern Virginia
… in moderate to high levels of mortality, and in antifeedant and repellency responses. Likewise, soybean field trials indicated that a single application can reduce stink bug numbers for up to two days after treatment; however in tomato field trials multiple weekly applications did not result in …

A comparison of the insecticidal properties of New Zealand native and other plants
… tested. Forty plant extracts were screened for antifeedant activity against LBAM and TAW, using artificial diet squares in a two-way choice test. A feeding index (FI = (C-T / C+ T) X 100) was used, in which C = the mean weight of control squares eaten and T = the mean weight of treated squares …

Studies in Marine Natural Product Synthesis, Isolation and Ecology
… were assessed. Alkaloids were species specific antifeedant agents against important consumers. These alkaloids may have a long term detrimental effect on predator physiology, due to the well established ability of these alkaloids to interfere with cell proliferation. Ascididemin elicited …
