Life-history studies of the coffee berry borer (hypothenemus hampei, scolytidae) on coffee trees in southern Mexico
1. A series of experiments involving artificial infestation of coffee trees with coffee berry borer were carried out in Chiapas, Mexico. Attacked berries were marked to identify time of infestation. 2. Berry samples were taken every 3-4 days for periods of up to 91 days and number of developmental stages present recorded. Two peaks of egg production occurred at about 10 and 50 days post-infestation. The second peak is probably the work of one or more daughters of the founding female. 3. Berries removed and placed on the ground 4 days after infestation, developed significantly (P < 0.0001) larger numbers of eggs than berries remaining on the tree
