ABSTRACT
A detailed tree hole survey for Aedes aegypti was carried out in the town of Arima, Trinidad. 8,045 trees were inspected and 63 holes were found with larvae of Aedes aegypti. The height of the positive holes varied from near ground level to 34 feet. Most of the trees found positive were common fruit trees. 25 of the 52 found positive were either breadfruit or chataigne, two varieties of Artocarpus communis, 7 were avocado (Persea americana), and six were golden apple (Spondias cytherea). 55 of the 63 tree holes found positive, i.e. 87 percent, were above the height of the average perifocal sprayer and hence would have escaped the treatment in the normal course of operations. There was light breeding in most of the holes. In a few it was very heavy, e.g. a mango tree hole with 150 larvae and pupae. Also found in 9 tree holes during the course of this work were larvae of Haemagogus spegazzinii. All the tree holes were treated with brickettes of benzene hexachloride in plaster of paris. (AU)
