So Stamp and Yang examined how the tomato fruitworm, fall armyworm, and tobacco hornworm-all tomato pests-respond in the laboratory to a diet laced with different combinations of three tomato allelochemicals-chlorogenic acid, rutin, and tomatine. They conducted tests at 21#161#C and 10#161#C, typical springtime day and evening temperatures for Binghamton, and at summer norms of 26#161#C and 15#161#C, they report in the June Ecology.
Tomatine and rutin, for example, each harmed the tobacco hornworm more in the spring temperatures than in the summer conditions.
The focal allelochemicals were the glycoalkaloid tomatine and the catecholic phenolics rutin and chlorogenic acid.
Depending on prior diet, tomatine can stimulate or deter feeding (Yamamoto and Fraenkel 1960b, De Boer and Hanson 1987), but the degree to which M.
Cholesterol alleviates the negative effects of tomatine on insects (Campbell and Duffey 1981, Bloem et al.
The three tomato allelochemicals were absent or at their maximal concentrations found in tomato leaves: tomatine (0 or 5 [micro]mol/g fresh mass (fm) of diet), chlorogenic acid (0 or 20 [micro]mol/g fm), and rutin (0 or 20 [micro]mol/g fm).
We conducted this experiment for each of the three tomato allelochemicals, using the 5-[micro]mol tomatine diet, 20-[micro]mol chlorogenic acid diet, and 20-[micro]mol rutin diet.
Tomatine concentration was not affected by thermal regime but did decline with incubation time.
There was an additive effect of tomatine to either chlorogenic acid or rutin, which slowed developmental rate further (P = 0.0001) [ILLUSTRATION FOR FIGURE 2A OMITTED].
There was a rutin by tomatine interaction (P [less than] 0.015).
sexta caterpillars was influenced by thermal regime and the interactions of thermal regime and tomatine (Table 2, [ILLUSTRATION FOR FIGURE 4A, B OMITTED]).
