| Summary: | A study to determine the growth and development of B. dorsalis reared on sweet potatoes-based artificial diet (Ipomoea batatas L.) was conducted under laboratory conditions. Four
types of diets used were; orange sweet potato (OSP), purple sweet potato (PSP), white sweet
potato (WSP) and wheat germ (WG) as a standard diet. Biological parameters recorded were;
number of pupae, pupae weight (mg), pupae and adult survival (%), number of adult
emergences, developmental time from eggs to adults’ stage (day), and adult longevity (day).
Results showed that among the diet tested, the WG based diet displayed a significant difference
(P<0.05) on the growth and development of B. dorsalis particularly on number of pupae, pupa
and adult survival and developmental time from egg to adult. However, no significant
difference (P>0.05) was shown on pupa weight between WG, OSP, and WSP diet. Adult
longevity of B. dorsalis also showed no significant difference (P>0.05) among all the diets.
Based on the results obtained, the growth and development of B. dorsalis reared on sweet
potatoes based diet was as good as the standard wheat germ-based diet and showed a potential
as a main new source of diets for B. dorsalis mass rearing especially in biological control
program of the fruit flies. |
