Site and Insemination Time of <em>Glossina palpalis palpalis</em> (Robineau-Desvoidy, 1830) in a Forest Area, Côte d’Ivoire

| Summary: | Spermathecae of female Glossina palpalis palpalis were examined to obtain data on their insemination. The study was conducted near the village of Zomenin in the forest area of Daloa (lat. 7-6° N, long. 7-8° W) in Côte d’Ivoire. Glossina were caught with Vavoua traps in four types of tsetse fly biotopes: coffee plantation (pupa site), edge between coffee plantation and forest, footpaths, and village outskirts. Out of 9175 Glossina examined, only a few had empty spermathecae (0.83%). The majority of virgin Glossina were immature females, which therefore had not fed yet (93.42%). They were mainly collected on pupa sites (71.05%) or on their edges (19.74%). No virgin female was found among Glossina that were 10 to 39 days of age. On the other hand, 0.05% of the 4460 very old Glossina (i.e. over 40 days of age) had empty spermathecae. Results suggest that Glossina insemination took place in pupa sites, a few days only after emergence of the imago (1-3 days). In addition, females of this species seemed to have mated before their first blood meal on the very site of emergence. |
