Behavioural response of alate Aphis craccivora Koch (Homoptera: Aphididae) to volatiles from different cowpea cultivars

Autor: Diabate, S. Deletre, E. Murungi, L.K. Fiaboe, K.K.M. Wesonga, J. Martin, T.

The cowpea aphid, Aphis craccivora, is a major insect pest of cowpea in Africa. Volatile organic compounds (VOCs) mediate plant–arthropod interactions that could be used in the management of insect pests. In this study, we established the VOC profile involved in the interaction between A. cracciv...

Behavioural responses of bean flower thrips (Megalurothrips sjostedti) to vegetative and floral volatiles from different cowpea cultivars

Autor: Diabate, S. Deletre, E. Murungi, L.K. Fiaboe, K.K.M. Subramanian, S. Wesonga, J. Martin, T.

Bean flower thrips (Megalurothrips sjostedti) is a key pest of cowpea (Vigna unguicalata) in Africa. To better understand the interaction of M. sjostedti to cowpea cultivars to improve management efforts, we investigated the repellent properties of volatiles of four cowpea cultivars, namely Ex-Lu...

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...
