| Résumé : | Species of Coreidae (Heteroptera) cause "water soaked" lesions in their food plants. Such insects typically feed from parenchyma in and surrounding vascular tissues and also cause acropetal wilting and necrosis of small diameter shoots. Feeding by Mictis profana (Fabr.) in South Australia on the shoots of Acacia iteaphylla F. Muell. ex Benth. was found to cause a local, concurrent increase in both water content and free amino acid concentration, consistent with phloem unloading. Coreids, unlike other groups of phytophagous Heteroptera, secrete a salivary sucrase (alpha-D-glucohydrolase, EC 3.2.1.48) as probably the sole salivary carbohydrase, and tissues attacked by M. profana showed more sucrose hydrolysing activity than unattacked |
