Abstract

Prostephanus truncatus (Horn) is a pest of maize stored in Mexico, Central America, some parts of South America, and it is expanding rapidly in Africa since it was introduced to that continent. Control of this pest in storehouses is carried out with the massive use of pesticides. With the object of finding an alternative method of control, an electron microscope study was made of the mid intestine of adults and larvae. Detected in the mid intestine of adult. P. truncatus was the presence of a peritrophic membrane. This membrane is formed by an irregular grid composed of various layers which are absent in the mid intestine of the last larval stage of P. truncatus. This indicates that formation of the peritrophic membrane take place mainly during the pupal stage, for which P. truncatus may be controlled biologically by using transgenic plants with the specific information to interfere in the synthesis of this membrane.
