Contents The Ants of Africa
Cameroun - modern surveys and collections

Compiled from the following papers:-
Campo Forest canopy - Dejean et al. (2002) - 167 trees and 40 vines directly sampled by hand collecting at the canopy level.
Terminalia ivorensis plantation canopy - Watt, Stork & Bolton (2002) - Mblamayo Forest - 15 individual trees sprayed with pyrethrin insecticide (knock-down sampling) at each of two sites on three separate occasions; trees the 4-5 years old, no indication given as to whether the canopy was interlocking.
Oil Palm - Dejean, Djieto-Lordon & Durand (1997) - 615 palms distributed over 50 ha, in plantations at Mpundu and Mondoni.
Edge Vegetation - Akok, Campo Forest Reserve - Dejean & Gibernau (2000) - plants along the edge of a 500 m stretch of forest road - 369 plants from 48 species and 28 families.
Maize - in suburbs of Yaoundé - Dejean et al. (2000) - 460 maize plants along walls of houses, 167 plants in urban gardens, 106 at periphery of field station plots and 53 plants in the centre of a field.
Mbalmayo Forest leaf litter - Watt, Stork & Bolton (2002) - ten 1 m² samples of leaf litter and top soil from each of seven plots in plantation and forest note in Bolton, 2007).
Campo Forest soil - Bolton, Dejean & Ngnegueu (1992) - sampling of 20 m square quadrats in each of two 50 metre transects, turning over the top 10-15 cm, and examining dead wood. A further three quadrats were sampled set apart from the main transects.
Campo Forest dead wood on the ground - Bolton, Dejean & Ngnegueu (1992) - no sampling numbers given.
Cubitermes subarquatus termitaries - Campo and other forests - Dejean, Bolton & Durand (1997) - 90 termitaries dissected (65 active and 25 abandoned) - termiaries up to 200 cm high against tree trunks.
Procubitermes nests - Ottotomo and other forest - Dejean & Bolton (1995) - termitaries attached to the bark of large trees - Ottotomo and Ndupé forest - 18 parcels of 25 X 25 m in total; with 92 active and 25 abandoned termitaries.
Miscellaneous collections by the McKey ant-plant relations project, with short notes; see Ants collected in Cameroun by Debout & Dalecky, 2001 (updated January 2009).

The ant species and forms are listed in alphabetical order for ease of comparison across the table.
