Calling behavior of mass-reared and wild Anastrepha serpentina (Diptera: Tephritidae)
The calling behavior of mass-reared and wild males of Anastrepha serpentina (Wiedemann) (Diptera: Tephritidae) was studied both in the laboratory and in Þeld cage tests. In the laboratory, density (1, 5, and 10 males per container), age, and hour of day signiÞcantly affected calling behavior. Mass-reared males called independently of density, whereas wild males only called at densities of 5 and 10 individuals. Males of both strains started calling when they were 5Ð7 d old. The daily pattern of male calling was similar in both strains, starting at 0730 hours, and reaching a peak at 1330Ð1630 hours. Field cage tests showed that mass-reared males started calling when they were 5 d old; the period of peak calling was when males were 8Ð9 d old. In contrast, wild males began calling when they were 10 d old, reaching peaks when males were 13, 15, and 18 d old. Wild males tended to form leks to call during each day of the experiment, whereas mass-reared males only formed leks during 2 d, both strains displaying very low levels. During Þeld cage tests, males, independently of strain, displayed two calling peaks, one peak in the morning and one peak in the afternoon, whereas males observed in the laboratory only showed a single calling peak. The results are discussed in view of the effects of mass rearing A. serpentina males in relation to potential use of the sterile insect technique.
