Efecto del tiempo de disponibilidad del macho en la fecundidad de Harmonia axyridis Pallas (Coleoptera: Coccinellidae)


, : Efecto del tiempo de disponibilidad del macho en la fecundidad de Harmonia axyridis Pallas (Coleoptera: Coccinellidae). Folia Entomologica Mexicana 40(1): 47-52

It was determined the fecundity of Harmonia axyridis as related to the time span that males and females were kept together: one day, three days, seven days (7DP) and continuosly (SP). Models that describe the production of viable eggs as a function of the number of days shared by the two mates were defined. Treatments 7DP and SP favored the greatest fecundity; nonetheless, each female from the 7DP treatment laid 18 eggs as a daily average, while females on SP treatment laid 15. These results indicate that keeping male and female together during seven days is enough time to obtain the highest egg production in mass rearing of this lady beetle.
