ECOLOGICAL STUDIES ON SUBTERRENEAN TERMITE AND CONTROL AT ISMAILIA GOVERNORATE (EGYPT

Abstract

All experimental of the study were conducted at Ismailia Governorate, Al-Qassasien location and laboratory of wood borers and termites department, Plant Protection Research Institute, these studies was aimed to survey and identifying the common subterranean termites species and their distribution at Ismailia Governorate, moreover, through the light on some ecological aspects of the most widespread subterranean termite species, Also, effect of some weather factors on different activities of the most common species; Anacanthotermis ochraceus, and finely, evaluation the efficiency of some Chemical insecticides, IGRs, Bio-pesticide and Co-formulated mixture under field conditions, the results obtained could be summarized as following: Two species of subterranean termites were found at Ismailia Governorate, the first and most widely distributed namely A. ochraceus (Burm.), while the second and less distributed namely Psammotermes hypostoma (Desneux). Data revealed that the harvester subterranean termite A. ochraceus (Burm.) had two peaks of activity annually in both two years of study. The first and the highest one took place between January and April while the second was relatively small size, took placed between August and October. The results obtained demonstrated that both of rain and relative humidity has a positive significant effect on subterranean termite A. ochraceus activity while the other tested factors ( wind speed, solar radiation and mean temperature) has a highly significant negative effect in both two years of study. Data demonstrated that the different castes represented by 67.1, 32.7 ,0.18 and 0.0% for worker, nymphs, soldier and alates respectively, in the first year (2015/2016) and 72.9, 26.65, 0.226 and 0.15% for worker, nymphs, soldier and alates respectively, in the second year (2016/2017). Data revealed that the maximum of surface activity of subterranean termite occurred during the
