Reaction of twenty maize cultivars to Sesamia cretica and effects on the insect reproduction [electronic resource].

Includes references.

The objectives of the present study were: (1) to evaluate 20 Egyptian maize cultivars including the Bt corn (SC Ageeb) for resistance to the pink stem borer S. cretica under natural and artifcial infestation in two planting dates and (2) to study the effect of rearing this insect on maize plants of different resistance to S. cretica. Two fields and one laboratory experiments were conducted during 2005, 2006 and 2007 seasons. Results of the field experiment under natural Infestation recommended the use of the 1st planting date (2Oth of April) for more accurate evaluation, because of the more existence of this insect in large populations short & after mergence of plants at this time as compared with the 2nd planting date (I5 May).
