Corn insect pest

In Vietnam, and particularly in Gia Lam, Hanoi, average yields are low, prices are high, and local demand is not met. Reasons for low yields in Vietnam include climate change, drought, flooding and infestation by new species of insects. This study was done to identify the species of insects which are found in the corn fields of Gia Lam, Hanoi.

Carboxypeptidases were purified fromguts of larvae of corn earworm (Helicoverpa armigera), a lepidopteran crop pest, by affinity chromatography on immobilized potato carb-oxypeptidase inhibitor, and characterized by N-terminal sequencing. A larval gut cDNA library was screened using probes based on these protein sequences. cDNA HaCA42 encoded a carboxypeptidase with sequence similarity to enzymesofclan MC [Barrett,A.J.,Rawlings,N. D.& Woessner, J. F. (1998)Handbook of Proteolytic Enzymes. Academic Press, London.], but with a novel predicted spe-cificity towards C-terminal acidic residues....
