THE ALIEN PSYLLID MACROHOMOTOMA GLADIATA KUWAYAMA, 1908 (HEMIPTERA PSYLLOIDEA HOMOTOMIDAE): SPREAD AND DAMAGE OF A RECENTLY RECORDED PEST OF FICUS MICROCARPA TREES IN TUNISIA

Abstract

During an inventory study of Psylloidea species carried out in Tunisia, the alien psyllid, Macrohomotoma gladiata Kuwayama, 1908 (Hemiptera Psylloidea Homotomidae), recently recorded in the country, has been detected on ornamental Ficus microcarpa, in public and private parks and gardens in many locations of the urban areas of the governorates of Tunis and Ariana, showing a fast spread in the area. This psyllid species has been observed causing damages and vegetative disorders to Ficus trees, especially white wax secretion, leaf wrapping and honeydew excretion on leaves and twigs. The number of infested trees increased from our first observations in late 2020 to early 2021. An Anthocoris sp. (Hemiptera Anthocoridae) has been observed to naturally prey on M. gladiata in many investigated locations.
