alpha-Methylene-gamma-butyrolactone (tulipalin A), which has been found to
possess effective insecticidal activity against Thrips palmi (Thysanoptera;
Thripinae), was examined on several insect pests. This compound caused hig
h mortality against thrips species such as Frankliniella occidentallis and
Frankliniella intonsa. In addition, some mortality was observed against oth
er agricultural pest species. It is considered that alpha-methylene-gamma-b
utyrolactone has a wide spectrum of insecticidal activity.
