Three insect groups, known from the literature, were confirmed to make up a seed pest complex in cowpea fields in Benin Republic (West Africa). Several species of heteropteran pod‐sucking bugs (PSBs), two lepidopteran species, namely Maruca testulalis (Geyer) and Cydia ptyehora (Meyrick) and the ...

The interactions between cowpea and one of its key pests, Megalurothrips sjostedti (Trybom), were evaluated via a simulation model based on three modules building the core of the cowpea growth model, i.e. the time-varying distributed delay, the functional response acquisition function, and the me...

Stage-specific survival rates of cowpea seeds were evaluated in fields planted during both cropping seasons of 1991 and 1992 in southern Benin using Manly's regression model. Considerable seed damage could be recognised in all seed growth stages and reflected the variable pest infestations during...
