|Caterpillars Turn to Cannibalism: Study|
The Scientist - 7/10/2017. By Abby Olena - When plants come under attack – by a hungry caterpillar, for instance – many of them activate defenses that make their foliage less tasty, less nutritious, or toxic. But until now, scientists weren’t sure what the consequences of these plant defenses were for the caterpillar. In a paper published today (July 10) in Nature Ecology & Evolution, researchers have shown that a tomato (Solanum lycopersicum) plant’s protections can encourage beet armyworm caterpillars (Spodoptera exigua) to cannibalize other caterpillars.
