Abstract:

Water was used to collect maturing larvae of Anastrepha suspensa (Loew) as they moved out of the rearing medium. With a 14-h photophase at 25–26°C, hourly departures of larvae from the medium began to accelerate 4–5 h before initiation of the light phase. Larval departure peaked each day during the 1st h of the photophase and more than 50% were collected in the first 5 h of the period. In continuous darkness, mature larvae moved out of the medium but the rate per hour never exceeded 5% of the total larval collection.

Development was delayed by holding larvae in water. There was a difference of 1 day in peak of emergence between the control and in larvae remaining in water for 24 h. This occurred without a lengthening of the overall emergence period.

Mature larvae could be held in water for ca. 12 h with no marked effect on emergence. Mortality reached ca. 10% in larvae kept in water for 16 h and increased to ca. 20% when held for 24 h. Holding larvae in water for 16 h or longer resulted in more pupae retaining a larval form and a reduction in emergence.
