Bioecology of the cowpea pod weevil Piezotrachelus varius Wagner (Coleoptera: Curculionidae), and cowpea seed damage

Autor: Ntonifor, N. Edimengo, P. Tamo, M.

The bioecology of the cowpea pod weevil, Piezotrachelus varius, and post-harvest seed losses were studied in the laboratory and in cowpea fields in the Western Highlands of Cameroon during the first and second cropping seasons of 1999 and 2000. Adult weevils appeared before flowering and fed on c...

Incidence of Maruca vitrata f. on cowpea in the sudano-sahelian zone of Niger

Autor: Zakari, O.A. Baoua, I. Amadou, L. Dannon, E. Tamo, M. Mahamane, S. Pittendrigh, B.R.

The incidence of the key insect pest of cowpea (Vigna unguiculata L. Walp), the legume pod borer Maruca vitrata F., was investigated with light trap in the Sudano-Sahelian zone of Niger in 2014 and 2015. The results revealed that the first larvae appeared in August (0.03 ± 0.03 to 2.48 ± 0.32 lar...

Bioactivity of Alstonia boonei De Wild leaf alkaloid on the growth and development of Maruca vitrata Fab.

Autor: Oigiangbe, O.N. Tamo, M. Igbinosa, I.B.

The bioactivity of Alstonia boonei De Wild leaf alkaloid was tested under laboratory bioassay against the legume pod borer, Maruca vitrata Fabricius. The alkaloid was incorporated into standard M. vitrata artificial diet at five doses [0.00 % (Control), 0.02 %, 0.05 %, 0.10 % and 0.20 %], and fed...
