In 1994, the USA followed when the Calgene Company got the first approval to commercialize a genetically modified tomato ‘Flavr Saver TM’, the delayed ripening […]

Genetic control strategies involve alterations of a targeted pest’s ability to reproduce or the insertion of some deleterious character into a pest population. Genetic control is a form of biological control of pest species which exploits the insect’s mate-seeking expertise to introduce genetic abnormalities (typically, but not necessarily, dominant lethal mutations) into the eggs of […]

While studying the biology of the screwworm fly, Cochliomyia hominivorax (Coquerel), he observed that the female fly mated only once (monogamous). From this, he argued that if the males of […]
