“…Likewise, similar attention has been given to antennal sensillar structures in lepidopteran forest pest species. They include the teak skeletonizer Eutectona machaeralis (Lan et al 2020), the spruce budworm Choristoneura fumiferana (Albert and Seabrook 1973) and the Chinese pine caterpillar Dendrolimus tabulaeformis (Zhang et al 2013). A comparative analysis of the antennae of Trichoptera, and basal and derived Lepidoptera species, revealed that a relationship exists between the proportions of certain sensilla types, and the type of sex pheromone used (Yuvaraj et al 2018).…”

The physiology and morphology of insects largely explain the immense adaptability of these organisms to forest ecosystems. This chapter presents an opportunity to review the basics of insect development, the morphology of the different stages and the organ systems that comprise them. The broad categories immature stages and developmental trajectories toward the adult are summarized. Important physiological systems involved in insect behavior such as sensory organs, the nervous system and locomotion are also reviewed. Concise reviews of digestion, immunity and reproduction provide the reader with a basic understanding of how insects interact with their hosts and pathogens and propagate. Together, these topics should convey the fundamental importance of insect form and function in forest entomology.

“…Afterward, specimens were critical-point dried for 1 h with CPD 030 (Micro Technology Hong Kong Ltd., Hong Kong, China), and then mounted on a holder from two sides, the dorsal side and ventral side, using double-sided adhesive tape and gold coated with the Eiko IB•3 Ion sputter coater (Hitachi, Tokyo, Japan). Sensilla were observed and micrographs were captured from different directions at 10 kV using the QUANTA 200 FEG scanning electron microscope (Feicompany, Hillsboro, OR., USA) (Lan et al, 2020).…”

“…Eutectona machaeralis (Walker) (Lepidoptera: Crambidae), is a serious pest that feeds on the mesophyll of teak, leading to a significant decline in the photosynthesis of the leaves. 4 The annual outbreak of these pests happens in teak-growing regions of China, India, and Malaysia. 5 The P. machaeralis females deposit their eggs near the midrib of the leaves, completing the life cycle within 23 days.…”

The leaf skeletonizer, Pyrausta machaeralis (Lepidoptera: Crambidae), is a serious insect pest of teak (Tectona grandis) in China. The application of insect pheromones is widely applied as an environmentally friendly technology for integrated pest management (IPM). In the present study, crude extracts of sex pheromone glands of calling P. machaeralis females were collected and then analyzed using gas chromatography/electroantennographic detection (GC/EAD) and gas chromatography−mass spectrometry (GC−MS). The combination of infrared spectroscopy (IR) and nuclear magnetic resonance (NMR) spectrometry was used for structure identification. Afterward, their electrophysiological and behavioral activity was evaluated in the laboratory and field. Herein, we eventually determined two active components, E-11-tetradecenyl acetate (E11-14:Ac) and Z-11-tetradecenyl acetate (Z11-14:Ac), at a ratio of 96:4, as the sex pheromone of P. machaeralis. The identification of sex pheromones would facilitate the development of efficient strategies for monitoring and controlling the field populations of P. machaeralis.
