Trenching is a strategy of herbivorous insects for avoiding ingestion of toxic phloem latex. (A) Artificial trenching releases phloem latex (broken arrows). The isolated semi-circular area is cleared from phloem latex as demonstrated by a cut from which no exudate emerges (left arrow head). In contrast droplets of exudates (arrows) appear from a cut outside of the trenched area (right arrow head). (B) Cucurbitacin B is present in most cucurbits.
