The identification of Afrotropical hoverflies is very difficult because of limited recent taxonomic revisions and the lack of comprehensive identification keys. In order to assist in their identification, and to improve the taxonomy of this group, we constructed a reference dataset of 513 COI bar...

Parasitism of noctuid stemborer eggs was assessed in monthly surveys in maize fields in southern Benin, from May 1995 to October 1996, and on alternative hosts, i.e. wild grasses, during the dry season from November 1995 to February 1996. Sesamia calamistis was the most prevalent stemborer specie...

We collected twigs of Lannea nigritiana (Sc. Elliot) Keay attacked by the girdling cerambycid Analeptes trifasciata F. in the Lama forest of central Benin, West Africa. Emergence data from A. trifasciata wood samples revealed a diverse insect fauna, which consisted of 27 primarily coleopteran spe...

The endophagous hyperparasitoid Prochiloneurus insolitus (Alam) was offered various stages of Epidinocarsis lopezi (De Santis), a primary parasitoid of the cassava mealybug (CM) Phenacoccus manihoti (Matile-Ferrero). Embryos were surrounded by a trophamnion. Larval development involved four insta...

The biology and behaviour of the signiphorid Chartocerus hyaipennis (HAYAT) were studied in the laboratory on Epidinocarsis lopezi (DE SANTlS), a parasitoid of the cassava mealybug Phenacoccus manihoti MATlLE-FERRERO. Only mummified secondary hosts, i.e. mealybugs, were accepted for ovi-position....
