The methyl ketones are toxic to planidia, but at least part of the effect is due to other factors, possibly physical entanglement. Both species can be affected indirectly by methyl ketones in the diet of the host. 2-Undecanone reduces the percentage ofA. marmoratus larvae that reach pupation. This effect is evidently due to premature death and desiccation of the host pupa caused by 2-undecanone. 2-Tridecanone in host diets had no effect onA. marmoratus. InE. bryani, 2-tridecanone in the diet of the host reduced the number of parasitoids yielded by each parasitized host, although not the overall percentage of hosts parasitized. 2-Undecanone in the diet of the host had no effect onE. bryani.}, number={3}, journal={Journal of Chemical Ecology}, publisher={Springer Science and Business Media LLC}, author={Farrar, R.

Four chemical constituents of the wild tomato, Lycopersicon hirsutum f. glabratum, PI 134417 were evaluated in artificial diet as growth inhibitors to Heliothis zea (Boddie): alpha-tomatine, chlorogenic acid, beta-caryophyllene and alpha-humulene. All caused small increases in developmental time, and, except for chlorogenic acid, small decreases in pupal weight. These changes may be too small to be of biological significance in host plant resistance. Our results suggest that the usual method of evaluating growth inhibitors, which is to weigh the insects after a fixed feeding period, is inadequate to assess the biological significance of any observed growth inhibitory effects. Because differences in weight after fixed feeding periods do not always translate into equivalent changes in developmental time or final weight, measurement of actual developmental time may be more appropriate.}, number={1}, journal={Journal of Entomological Science}, publisher={Georgia Entomological Society}, author={Farrar, Robert R. and Kennedy, George G.}, year={1990}, month={Jan}, pages={46–56} }

However, mean weight incorporates weight change, which is a function of digestive efficiency; relative consumption rate, therefore, is inherently dependent on physiological responses. In short-term (within one instar) experiments quantifying insect behavior, the maximum amount of food an insect can eat is not likely to vary directly with body weight. Under such circumstances, it is more appropriate to relate consumption to the weight of the insect at the beginning of the test, not to mean weight. The use of mean weights produces a similar bias in relative growth rate.}, number={5}, journal={Annals of the Entomological Society of America}, publisher={Oxford University Press (OUP)}, author={Farrar, Robert R. and Barbour, James D. and Kennedy, George G.}, year={1989}, month={Sep}, pages={593–598} }
