“…Many researchers documented that sensilla chaetica were likely mechanoreceptors, which monitored food texture and coordinated the power output of the muscles and the positions of the labrum and the mandibles (Schneider ; Zacharuk ; Zacharuk and Shields ; Dey et al . , ; Goldsmith et al . ).…”

Xu, L., Zhang, L., Yang, Y., Ren, L., Wang, T. and Zong, S. 2015. Morphology of antennal, maxillary palp and labial palp sensilla in different larval instars of the Asian long-horned beetle, Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae). -Acta Zoologica (Stockholm) 00: 000-000.The Asian long-horned beetle (ALB) is one of the most important international trunk-boring insect pests of forest trees, which has caused enormous losses in the forests of China, the USA and some countries in Europe. To investigate the morphology of the antennal, maxillary palp and labial palp sensilla in the five larval instars of the ALB, scanning electron microscopy was used to determine the typology, morphology, number and distribution of the sensilla. The antennae had two types of sensilla: the sensilla twig basiconica (s.t.b.) and sensilla basiconica. Three different types of sensilla were observed on the maxillary palps, which were the sensilla digitiformia, the sensilla chaetica and the s.t.b. The labial palps had two types of sensilla: the sensilla chaetica and the s.t.b. The s.t.b. had seven total subtypes, and the sensilla basiconica had two subtypes. The typology, quantity and distribution of sensilla on the antennae, maxillary palps and labial palps remained constant in the five larval instars, but the dimensions of all sensilla types increased throughout the development. We discussed the mechanoreception and the chemoreception of ALB larvae inside the host tree to provide a theoretical understanding and information for further research on the behaviour and the electrophysiology of this devastating forest pest.Shi-xiang Zong, Beijing Key Laboratory of Forest Pest Control, Beijing Forestry University,

“…Sensillae chaetica were reported as hair like and the longest sensillum found in the mala of maxillae and ligula of the 2 nd , 4 th larval instar and on the pre-pupal stages of S. granarius. Many researchers reported that sensillae chaetica were play an important role in monitoring food textile coordinated the power output of the muscles and the positions of the labium, labrum and the mandibles and may act as mechanoreceptors ( Zacharuk and shields 1991;Dey et al 2009Dey et al , 2011Goldsmith et al 2014). Xu et al, (2015) reported that sensillae chaetica play an important role in the movements of the maxillary and labial palps for larval Anoplophora glabripennis as well as detect the structure of the tunnel.…”

The granary weevil S. granarius is one of the most important stored product pests on the world, because of its damage. This pest is the main reason of the post harvest losses in world production; as a result of adults and larvae infesting and feeding on stored grains. The morphology and ultrstructure of the mouth parts and antennae of the pre-adult stage of S. granarius was investigated using scanning electron microscopy. The antennae and mouth parts of the granary weevil larvae and pre-pupal stage have a number of very interesting sensillae. The antennae have one large sensillum with different morphological appearance. Pores have been noticed on both sides. This one is known as sensilla basiconica. The pores may have an auditory function. The 2 nd , 4 th , and prepupal stages have a very strong mandibles each of them have two long sensillae. On the lateral view of the distal part of maxillary palp there was a digitiform sensillum. The digitiform organ is considered as a hygrothermo-receptor and was located on the lateral surface of the last segment of the larval maxillary palp. Another type of sensillae have been present and called chaetica sensillae, sensillae like a peg (sensilla twig basiconica) and campaniform sensilla which are located on the upper surface of the antennae of the 2 nd , 4 th larval instar and prepupal stages.
