In Canada, trembling aspen is their favourite host tree, which can produce an inducible protein, trypsin inhibitor (TI), to inhibit trypsin, a major proteolytic enzyme in cater-pillars' midguts. To determine the digestion-inhibiting effect of TI on M. disstria, this study focused on the performance of second instar larvae with different levels of TI on both balanced and low protein diets. Both protein deficiency and higher levels of TI impaired the growth of caterpillars, but the impairing effect of TI only appeared on the caterpillars fed on balanced diet. This study confirmed the digestion-inhibiting function of TI as a defense of aspen against forest tent caterpillars. Also, it suggested that caterpillars were able to regulate their growth under severe protein deficiency, possibly as an adap-tation to this defense.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Zhe Shi,Yves Gélinas,Emma Despland\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3639034945\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783639034943\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e VDM Verlag Dr. Mueller E.K.\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 06\/16\/2008\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 88\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.28lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.18d","brand":"Zhe Shi","offers":[{"title":"Paperback","offer_id":48454041862399,"sku":"9783639034943","price":52.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_806236f8-4489-4f13-ab0d-ac8b7fa0576d.jpg?v=1777303834","url":"https:\/\/www.whiterainbookhouse.com\/products\/plants-vs-caterpillars-is-trypsin-zhe-shi-9783639034943","provider":"WR Book House","version":"1.0","type":"link"}
