- Abstract
Antennae, the primary sensory organs of insects, contain numerous sensilla responsible for detecting chemical and physical stimuli essential for host location, communication, and orientation. Although the antennal sensilla of many insect groups—including Gelechiidae—have been well characterized, no such descriptions exist for Anacampsis phytomiella (Busck, 1914), a pest that exclusively infests cashew (Anacardium occidentale L.) and can cause yield losses of up to 80%. This study aimed to identify and compare the types of antennal sensilla in males and females of A. phytomiella using a Scanning Electron Microscope (SEM). Both sexes have filiform antennae of similar size. Nine types of sensilla were identified: trichoid, basiconic,... (More)
Antennae, the primary sensory organs of insects, contain numerous sensilla responsible for detecting chemical and physical stimuli essential for host location, communication, and orientation. Although the antennal sensilla of many insect groups—including Gelechiidae—have been well characterized, no such descriptions exist for Anacampsis phytomiella (Busck, 1914), a pest that exclusively infests cashew (Anacardium occidentale L.) and can cause yield losses of up to 80%. This study aimed to identify and compare the types of antennal sensilla in males and females of A. phytomiella using a Scanning Electron Microscope (SEM). Both sexes have filiform antennae of similar size. Nine types of sensilla were identified: trichoid, basiconic, chaetic, coeloconic, styloconic, squamiform, auricilic, uniporous peg, and Böhm’s bristles. Trichoid and basiconic sensilla are abundant in both sexes, while coeloconic and styloconic sensilla are more prevalent in females. Uniporous peg sensilla are the least abundant sensory structures on the antennae of both sexes. Sensilla size varies with location, being larger at the distal ends of the antennae. It is concluded that the A. phytomiella antennae possess nine types of sensilla, with trichoid and basiconic sensilla being the most abundant. It is the first detailed description detailed of sensilla morphology in this species. This study provides a detailed morphological characterization of the sensilla in A. phytomiella, contributing to a better understanding of their biological roles and supporting further investigations into their physiological functions.
