The fourth instar nymphs of each pod-sucking bug species caused a significantly higher cowpea yield reduction than their respective adults. Similarly, infestation on young pods compared to mid-fill and mature stages resulted in significantly higher yield reduction. The results suggest that infestation levels of two fourth instar nymphs of <jats:italic>A. curvipes<\/jats:italic> or three fourth instar nymphs of the other four pod-sucking bug species per young pod should be adequate for screening of cowpea varieties for resistance to the coreoid bugs.<\/jats:p>","DOI":"10.1017\/s0007485307004695","type":"journal-article","created":{"date-parts":[[2007,2,14]],"date-time":"2007-02-14T05:24:00Z","timestamp":1171430640000},"page":"1-7","source":"Crossref","is-referenced-by-count":9,"title":["Comparative assessment of feeding damage by pod-sucking bugs (Heteroptera: Coreoidea) associated with cowpea, <i>Vigna unguiculata<\/i> ssp. <i>unguiculata<\/i> in Nigeria"],"prefix":"10.1017","volume":"97","author":[{"given":"O.L.","family":"Soyelu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.E.","family":"Akingbohungbe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2007,2,14]]},"reference":[{"key":"S0007485307004695_ref014","first-page":"17","article-title":"Observations on pod-sucking bug populations on cowpea at Mokwa, Nigeria","volume":"33","author":"Suh","year":"1986","journal-title":"Tropical Grain Legume Bulletin"},{"key":"S0007485307004695_ref004","unstructured":"FAOSTAT (2005) Provisional 2004 production data.
