القدرة التكاثرية لخنفساء اللوبياء Callosobruchus maculatus F. على بعض المدخلات الوراثية للعدس و علاقتها بوزن البذور و حجمها

الملخص EN

The biology of cowpea weevil Callosobruchus maculatus F.

was studied in some lentil genotypes seeds under laboratory conditions.

The genotype ILL5755 was the most suitable for penetrating larva into the seeds (59 larva), and completing its development (56 larva) during 21.5 day from eggs to adults.

The least suitable genotype seed was ILL 7713, one adult laid 35.5 eggs, 25.5 larvae had developed, but only 6 larvae could penetrate with no adult emerged.

The ILL7950 had low total eggs, lowest hatched eggs with penetrated larvae, male, female, total adult insects.

Also, low ratio for pipe out of eggs, penetration, adults and seeds weight lost.

A high amount of eggs was on largest seeds.

The ratio of seed’s weight lost and total adults insects decreased on seeds of genotypes, which had medium weight for 100 seeds (2.5-3.5g) in contrast with genotypes, which had less than 2.5g or more than 3.5g.
