Abstract:

Oviposition by Anthonomus grandis Boheman was observed in detail in the field. Average time from initial mating to 1st oviposition was 21 minutes, but the oviposition time for overwintered females was longer than for females of the subsequent generation. The process of puncturing the square and depositing the egg required an average of 6 1/4 minutes for overwintered females and 4 1/2 minutes for females of the subsequent generation. Females deposited almost 1 egg per hour at a fairly smooth pace throughout the day starting at about 0800 hr. Apparent peaks were noted between 0900 and 1000 hr, and between 1200 and 1300 hr. The number of eggs deposited per hour was also somewhat reduced in the overwintered generation.
