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.
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.
