Natural Pest Regulation on Orphan Crop Legumes in Africa (NaPROCLA)


Department for International Development UKAID

Titre : Natural Pest Regulation on Orphan Crop Legumes in Africa (NaPROCLA)

Pays : Kenya

Numéro du projet : GB-GOV-13-FUND—GCRF-BB_R020361_1

Organismes de mise en œuvre : University of Greenwich

Durée : Actual Start 01 Jul 2018 // Actual End30 Jun 2021

Objectifs partiels
The overarching objective is to understand the specific role of key plant and invertebrate taxa in natural pest regulation on orphan crop legumes and exploit this for the management of Aphis fabae (black bean aphid) and Maruca vitrata (legume pod borer), two major pests on East African orphan legume crops (including common beans, cowpea, pigeon pea and lablab), through ecological intensification. This work will directly address a main theme of the call : managing crop pests and diseases. The key aims of the project will be : 1. Determine how integration with other pest management approaches including host plant resistance and plant based pesticides influences natural pest control in landscapes that are botanically diverse or depauperate. 2. Determine how intercropping of legumes with cereals - a common farming practice to maintain soil quality - influences the delivery of natural pest regulation. 3. Combine benefits of biodiversity/genetic variation within regionally important indigenous and ’orphan’ crops by cultivation within mixed and plant-diverse cropping systems, harnessing the full agronomic potential of beneficial organisms for enhancing crop productivity or countering pests. By focussing on orphan legume crops that provide critically important nutrition through protein and micronutrients, our project will enhance sustainable production that supports food and nutritional security (and safe food). This will support the delivery of rigorous evidence to promote environmentally sustainable agriculture that is relevant both for local production traditions and practises but also focussing on women who are the primary growers of legumes. The specific objectives are as follows. Objective 1. Evaluation of the pest management potential of natural enemies through ecological intensification of field margins. We will provide evidence to inform the design and development of new interventions that harness ecosystem services of natural pest regulation. In previous field activities we have established the diversity and nature of natural enemies of pests in legume cropping systems but it is still not known which species are the most important for natural pest regulation in orphan crop legumes and which plant species provide the most effective field margin support. This objective will address this by comparing different field margin types/managements for their capacity to support natural pest regulation and good yields.
