Optimization of extruder cooking conditions for the manufacture of fish feeds using response surface methodology

Autor: Irungu, F.G. Mutungi, C. Faraj, A. Affognon, Hippolyte D. Ekesi, S. Nakimbugwe, D. Fiaboe, K.K.M.

A composite blend consisting of sunflower cake, maize germ, wheat bran, fresh water shrimps and cassava flour was extruded using a single-screw extruder to produce expanded fish feed pellets. The effects of temperature (80–120 C), die diameter (2–4 mm), and feed pre-conditioning time (50–150 s; ...

Effects of host age and density on the performance of Apanteles hemara (Hymenoptera: Braconidae), a larval endoparasitoid of Spoladea recurvalis (Lepidoptera: Crambidae)

Autor: Othim, S.T.O. Ramasamy, S. Kahuthia-Gathu, R. Dubois, T. Ekesi, S. Fiaboe, K.K.M.

The amaranth leaf-webber, Spoladea recurvalis (Fabricius; Lepidoptera: Crambidae), is a serious pest of Amaranthus sp. in Africa and Asia. Apanteles hemara (Nixon; Hymenoptera: Braconidae) is by far the most important larval endoparasitoid of the amaranth leaf-webber. We examined the effects of h...

The effects of pest-resistant amaranth accessions on the performance of the solitary Endoparasitoid apanteles hemara (Hymenoptera: braconidae) against the amaranth leaf-webber Spoladea recurvalis (Lepidoptera: crambidae)

Autor: Othim, S.T.O. Ramasamy, S. Kahuthia-Gathu, R. Dubois, T. Ekesi, S. Fiaboe, K.K.M.

The leaf-webber Spoladea recurvalis F. is the most devastating pest of amaranths in East Africa. Recent collaborative research in Asia and East Africa revealed one highly resistant amaranth accession (VI036227) to the pest and seven moderately resistant ones (RVI00053, VI033479, VI044437-A, VI047...
