Abstract

Biological and morphometric studies of the different stages of Lucilia caesar, were carried out using three rearing media prepared from local materials as the test media, and the standard Snyder’s medium as control. The materials for the test media were: (i) Garri, soybeans, palmwine and liver (GSPL), (ii) Garri, soybeansand palmwine (GSP) and (iii) Pap, nono, cabbage and liver (PNCL). The Snyder’s medium consists of milk, yeast and bacto agar (MYA). There was no significant difference in the duration of larval instars and adult emergence for the blowflies reared in the standard, PNCLand GSPL media. For blowflies reared in GSP, duration of larval and adult stages was prolonged by about 48 hr and 5 days respectively, when compared with the flies reared from the other three media. The average length and width of each larval stage reared from the four media were not significantly different. Morphometrics of the adults showed that those reared from the GSPL and control media were longer, heavier, and laid significantly more eggs per female than adults reared from PNCL and GSP media. The GSPL medium was considered to be the most suitable alternative to MYA.

Résumé

L’etude biologiqueet morphometrique de divers stades de mouche (Lucilia sp.) utitisant trors miheux d’experience de produit locaux. Les produits utilise furent: (i) Tapioca, le soja vin depalme et foie (TSUF), (ii) Tapioca, le soja et vin de palme (TSV), (iii) Bouillie, “Nono”, chaux et foie (BNCF) la formule de Snyder était composé de: lait, leuvre et Agar (LLA).

Il n’ya pas eu une difference significative entre la duree des diverses stade de larves et l’apparition des adultes de mouche cultives en TSVF, TSV, BNCF. Pour les mouches cultivée en TSV la duree des stades de larves et d’adultes fut prolonge de 48 hr et de 5 jours respectivement par rapport aux mouches des autres milieux. La longeur et la largeur de chaque stade de larve des quatre cultures n était pas significativement different. L’etude morphometrique des adultes montra que ceux éleve en milieu (TSVF) et (LLA). Furent plus longue et plus lourd et pondurent significativement plus d’oef par femelle par rapport aux adultes éleve dans les milieux PNCL et GSP. Le milieu (1) était consideré comme le meilleur milieu alternatif apres celui de Synder.
