Studies of wound myiasis among sheep and goats in north Sinai governorate, Egypt

Studies of myiasis of sheep and goats in North Sinai resulted in the identification of 21 species of myiasis producing flies. The predominant species was Musca domestica, followed by Lucilia sericata and the least abundant was M. albina. In general, sheep were more infested with wound myiasis than goats. The overall infestation rate was high in summer, followed by spring then autumn. The least rate of infestation was winter. As to the different areas examined, the high rate of infestation was in Bir-Al-Abd, followed by El-Hasanah, El- Arish, El-Sheikh Zowaid and, lastly, Rafah. The factors predisposing to wound myiasis in a descending order of importance in goats were open wound, shearing wound, caseous lymphadenitis, foot rot, fecal staining, ophthalmo or facial eczema, horn fracture, rumen fistula and, lastly, posterior paralysis. In sheep, the most important cause was caseous lymphadenitis, followed by foot rot, then open wound and fecal staining, shearing wound and ophthalmo or facial eczema, otherwise more or less the same as in goats

Effect of temperature on the Developmental stages of wohlfahrtia nuba [Diptera: sarcophagidae]

Total developmental time of flesh flies Wohlfahrtia nuba [Wiedemann] from first larval stage to adult emergence was 34.7, 23.5, 18.7, 13.4 and 13.6 days when reared at 21, 25, 29, 33 and 37°C, respectively. There were no significant differerces between both sexes [P > 0.05], The overall mean of the larval duration periods was shorter [P < 0.05] than pupal duration periods. Estimates of the lower developmental threshold temperatures [t[L] were 12.8, 14.0 and 13.6°C and the thermal constant [K] were 116.8, 152.2 and 268.2 degree-days for larvae, pupae and total developmental time, respectively. Pupal mortality was low at all temperatures used. The fly reached their maximum weight in pupal and adult stages at 21°C. At all temperatures, the mean weight of pupa and adult was smaller [P < 0.001] in males than in females. The developmental rate, low mortality and greatest weight reached their optimal condition between 21 to 33°C
