Studies on termite preferences for cocoa progenies
Certain termite species have assumed pest status on cocoa seedlings in Ghana and the situation poses a serious hindrance to establishment of the crop in the country. Presently synthetic chemicals are the major means of their control but there is an increasing need to find alternative control measures in view of the hazards associated with such chemicals. One such option is the use of cocoa progenies that are less attractive to pest termites. An experiment was therefore carried out at Atosu to study the incidence of termite pests on nine cocoa progenies having T85/799, T60/887 or 10P as the female parent. Land preparation and transplanting were completed in April and june/July 2000, respectively. The design was a Randomised Complete Block Design. There were six plots (replicates)per progeny and 25 seedlings per plot, separated by 3-meter guard rows. From November 200 to December 2002 six randomly selected seedlings were examined monthly in each plot for symptoms of termite infestation and samples of the causative termites taken and preserved for identification. The dominant termite pests were unidentified species of Ascistrotermes and Amitermes. Progenies of T85/799 were the most attractive to the pests, followed by those of T60/887 and 10P.
