Intercropping for BBTD management

Sergine NGATAT, R. Hanna, A. J. Lienou, Enoh , A. Fotso Kuate, K.K.M. Fiaboe & P.L. Kumar
Banana bunchy top virus (BBTV) is transmitted persistently by the banana aphid, Pentalonia nigronervosa Coquerel. To effectively and sustainably manage BBTV threat, this study was conducted to determine the effect of intercropping on BBTV spread and aphid population dynamics. A field experiment was planted in September 2013; four plantain cultivars,-2 local plantains (Essong, Ebang) and two hybrids (PITA 23, PITA 24)- were intercropped with improved cassava variety (TMS 96/0023). Data were collected on aphid abundance...

Emmanuel Alamu, Busie Maziya-Dixon, Consent Sibeso, Elizabeth Parkes & Alfred Gilbert Dixon
The correct estimation of the mineral content of cassava (Manihot esculenta) genotypes is vital from a nutritional point of view. This study evaluated the effects of the storage root section, maturity, and sampling method on the macro- and microelements in yellow-fleshed cassava root genotypes. In total, 44 genotypes were grown in replicated field trials of 2 sets (set 25 and set 19) and were harvested at 9 and 12 months after planting. Two sampling methods,...

GF-120 and Control of Cucurbit crops in Benin

Rachid Hanna, Ginette Azandeme-Hounmalon, Désiré Gnanvosou & Adam S. Ahanchede
Fruit flies belong to family Tephritidae are the most destructive pests of horticultural crops in Benin, West Africa. Given their economic losses in zucchini and watermelon crops, the protein bait GF-120 was evaluated for its effectiveness to control cucurbits-infesting fruit flies The protein bait was applied to clusters of sorghum and castor bean planted in four corners alternately as a border crops. For over 2 years – 2008 to 2009, we conducted on-station trials at...

Banana aphid Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae) and ant interaction

Sergine NGATAT, Rachid Hanna & Pullikanti Lava Kumar
Banana and plantain (Musa spp) contribute to food security for about 70 million people in Africa and in Cameroon where it serves as source of income and food security. Nevertheless, Banana bunchy top virus (BBTV) transmitted by the banana aphid Pentalonia nigronervosa Coquerel is a serious threat to the production of bananas. An integrated management BBTV requires a good knowledge of aphid biology and ecology. Banana aphid has trophobiotic relationship with many species of ants,...

Rwanda Single Diseased Stem Removal Trials Data

Guy Blomme, Petronille Dusingizimana, Jules Ntamwira, Elizabeth Kearsley, Svetlana Gaidashova, Anne Rietveld, Boudy Van Schagen & Walter Ocimati
Bioversity and IITA saw great benefits for Rwandan farmers and the public agricultural administration should SDSR become an accepted option for the management of BXW. To achieve that, It was proposed to establish 4 on-farm pilot sites that function as combined demonstration plots as well as research platforms for RAB data collection and technical analysis.

Physicochemical alterations of plantain flour as affected by ripening stage and precursors

This project is aimed to sustainably enhance the adoption, productivity and utilization of endophyte primed high pro-vitamin A plantain cultivars and hybrids in the context of ISFM in smallholder farms in Nigeria, Cameroon and Gabon.

Using male and food bait attractants for monitoring of Bactrocera dorsalis and Ceratitis spp. in citrus orchards and B. latifrons in vegetable garden in IITA-Ibadan, Nigeria

Rachid Hanna, Désiré Gnanvossou & Andrew Ojetola
This study focused on the diversity, abundance and seasonal patterns of both indigenous and invasive fruit flie species, in addition to identifying the factors influencing their abundance in IITA-Ibadan agroecology, Nigeria. The study sought to provide necessary data to assess the efficiency of male and female attractants on monitoring various fruit fly species.

Interactions between the African weaver ant Oecophylla longinoda, the invasive fruit fly Bactrocera dorsalis and the egg-larval parasitoid Fopius arisanus in laboratory conditions, Benin, West Africa

Rachid Hanna, Ahandessi Anne-Marie Jésugnon, Désiré Gnanvossou, Alphonse Agbaka, Sunday Ekesi, Samira Mohamed & Hyppolite Aimé Bokonon-Ganta
The project aims to understand the interactions between the weaver ant Oecophylla longinoda (predator) and the wasp Fopius arisanus (parasitoid) two natural enemies of the tephritid fruit fly Bactrocera dorsalis and the impact of their simultaneous presence on the success of the biological control against this redoubtable insect pest infesting mango and other tree crops in Benin.

Auxin signaling and vascular cambium formation enables storage metabolism in cassava tuberous roots

David Rüscher, José María Corral, Anna Vittoria Carluccio, Patrick A.W. Klemens, Andreas Gisel, Livia Stavolone, Ekkehard Neuhaus, Frank Ludewig, Uwe Sonnewald & Wolfgang Zierer
Cassava storage roots are among the most important root crops worldwide and represent one of the most consumed staple foods in Sub-Saharan Africa. The vegetatively propagated tropical shrub can form many starchy tuberous roots from its stem. These storage roots are formed through the activation of secondary root growth processes. However, the underlying genetic regulation of storage root development is largely unknown. Here we report on distinct structural and transcriptional changes occurring during the early...

Feasibility of using male annihilation techniques for suppression of Bactrocera dorsalis and Ceratitis spp. in mango orchards in northern Benin

Rachid Hanna, Désiré Gnanvosou & Abiola I. Agnontchémè
This report summarizes the findings from male annihilation experiments in northern Benin using methyl eugenol - for suppression of Bactrocera dorsalis - and terpinyl acetate for suppression of Ceratitis spp. Methyl eugenol MATs maintained B. dorsalis male populations at less than 10% of its populations in the control orchards. Terpinyl acetate was also effective in suppressing Ceratitis spp. male populations, but was much less effective than methyl eugenol in the suppression of B. dorsalis.
