| Abstract: | "Anoplistes halodendri halodendri (Pallas, 1776) and Anoplistes halodendri ephippium (Stevens and Dalman, 1817) are two subspecies of the longicorn beetle A. halodendri (Coleoptera, Cerambycidae). In the recent years, these subspecies have been spreading rapidly in Hippophae rhamnoides and Hedysarum scoparium shrubberies in the Chinese provinces of Shanxi and Kingie, causing mass mortality of these shrubberies species and consequently leading to great damage to local ecological environment construction as well as high economic, ecological, and societal losses. To control their hazards effectively, here, we study and compare the types, densities, and distribution of antennal sensilla of A. h. halodendri and A. h. ephippium using scanning electron microscopy. Eight sensilla types were observed on the antennae of these two subspecies, including placoid sensilla (Ps), chaetica sensilla (ch) (types I-III), sensilla basiconica (b) (types I and II), sensilla gemmiformium (G), and auricillica sensilla (au). Ps predominated on the antennae of both A. h. halodendri and A. h. ephippium, followed by b and ch, and G and au. There were differences between the subspecies in the distribution and density of the different sensilla types, with ch I being found exclusively on the antennae of A. h. ephippium and b I and au on the antennae of A. h. halodendri only. With the exception of Ps, the densities of ch II, ch III, b II, and G on the antennae of A. h. halodendri were much higher than on the antennae of A. h. ephippium. These results provide sufficient evidence to clarify the receptive mechanisms used by these two subspecies of longicorn beetles and their responses to volatile semiochemicals released by their host plants as well as discuss their differences with respect to host and habitat selection" |
