TOXIC EFFECT OF SAP AND HEARTWOOD EXTRACTS OF SOME IRAQI TREES TO TERMITES (Microcerotermes diversus Silv., Isoptera, Termitidae)

The results of the recent study showed that the total extraction, namely, hexane, petroleum ether, and water, in both sap wood and heart wood of pine and cupresses trees showed a high percentage of mortality in termite, the general averages of mortality were : 46.3, 71.2, 61.1 and 72.3% respectively, while the total extraction for both sap wood and heart wood for platanus and poplar trees were of less effect on the termite. The general average were 33.9, 41.8, 43.0 and 44.2% respectively. Hexane extraction showed a high killing effect on termite workers. The general average of mortality was 59.5% followed by the petroleum ether and ethanol extraction equivalent mortality rates 59.0 and 59.3% respectively. Water extracts was of less effect on the termites with a mortality rate of 33.7%.
