Abstract

The Taita Hills swallowtail butterfly, Papilio desmondi teita, was reared in captivity on wild citrus (Rutaceae), Toddalia asiatica and Clausena anisata, in Ngangao Forest, Taita Hills, Kenya. The butterflies were exposed to the host plants for oviposition inside the laying buckets under ambient laboratory conditions. Results revealed that P. desmondi teita could only complete development on T. asiatica and but not on C. anisata in both seasons. The egg incubation period on T. asiatica was significantly shorter ( P < 0.001) compared to C. anisata during the first season ( P = 0.595) but not in the second season. The development period of the butterfly in 1st and 2nd seasons on T. asiatica was 81.13 ± 0.44 days and 112.15 ± 1.20 days, respectively, while a female-biased sex ratio was observed in the first and second seasons. Findings from this study indicate that T. asiatica was the most suitable host plant for development of P. desmondi teita.
