Action Programs for Rhynchophorus ferrugineus and Paysandisia archon
2017
The spread of invasive alien species is strongly associated with the rapid acceleration of human trade, tourism, transport, and travel over the past century, which have allowed these species to overcome natural geographic barriers. The best strategy to prevent the spread of invasive species is quarantine and eradication of initial foci. However, when invasive species appear to be established, the best approach should focus on containment and decreasing their impact through specific control measures. In this context, considering the rapid spread of the two palm pest species recently introduced in the Mediterranean area-Rhynchophorus ferrugineus (red palm weevil, RPW) and Paysandisia archon (…
Fine Structure of Antennal Sensilla of Paysandisia archon and Electrophysiological Responses to Volatile Compounds Associated with Host Palms
2014
Paysandisia archon (Lepidoptera: Castniidae) is a serious pest of palm trees. A comprehensive knowledge of the insect olfactory system is essential for the development of efficient semiochemical-based control methods. The olfactory sensilla are located particularly on the antennae, and these can detect plant volatiles that provide important cues for the insects in the search for their host plants. To date, the fine structure of P. archon antennal sensilla studies and their role in host-plant perception have not been investigated in great detail. Using light microscopy and scanning and transmission electron microscopy, the antennae of both sexes of P. archon are described here in detail, acc…
