“…Otherwise, if both sexes were studied, the authors either stated or implied that they were much the same. Where counts of antennal sensilla are reported from other curculionoids (Moeck 1968;Hatfield et al 1976;Dickens and Payne 1978;Bland 1981), they are comparable to what we report for the males and about double or triple that for the females of C. formicarius. If C. formicarius is the sister group of the rest of its genus (Wolfe 1991), then the similar pattern of sexual dimorphism in C. puncticollis indicates that this is part of the groundplan for Cylas.…”

“…At least 21 species of curculionoid beetles have been the subject of SEM studies, with special attention to the antennae (Borden and Wood 1966;Borden 1968;Moeck 1968;Borg and Norris 197 1;Mustaparta 1973;Payne et al 1973;Hatfield et al 1976;Smith et al 1976;Dickens and Payne 1978;Bland 1981;Whitehead 1981). Moeck (1968) reported moderate sexual dimorphism in the shape of the antennal club and total number of sensilla in Trypodendron lineatum (Olivier) (Scolytidae).…”

SEXUAL DIMORPHISM IN THE SWEET POTATO WEEVIL, CYLAS FORMICARIUS (F.) (COLEOPTERA: BRENTIDAE)

et al. 1997

The Canadian Entomologist 129: 61-69 (1997) Cylas formicarius (F.) shows a strong overall sexual monomorophism, with external differences noted in only three organs: (a) relative size of the hind wings; (b) form of the antenna1 club and numbers of its different types of sensillum; and (c) size of the compound eyes and their individual facets. We relate these to known or predicted behavioural differences. Eye dimorphism is used to test a theoretical rule on the relationship between differences in overall eye size and in the size of individual ommatidia. Some sexually monomorphic features are briefly discussed, including two types of putatively sensory hairs not found on the antennae. et S.J. Kays. 1997.

“…The sex differences in antennal sensilla on the terminal lobes are thus likely to be related to the male's ability to find and recognize a conspecific female. The sexual dimorphism in numbers and, in some species, types of olfactory receptors is common (Hatfield et al, 1976;Harbach and Larsen, 1977;Agren, 1985;Jourdan et al, 1995) and it is suggested that males have some sensilla specialized for the perception of female pheromones (Chapman, 1982). This hypothesis should be tested for D. ishigakiensis in the future.…”

Sexual dimorphism in body dimensions and antennal sensilla in the white grub beetle, Dasylepida ishigakiensis (Coleoptera: Scarabaeidae)

The white grub beetle, Dasylepida ishigakiensis shows sex dimorphism in body dimensions and abundance of antennal sensilla. Body length was almost identical in the two sexes, but the abdomen was significantly longer in females than in males. Males had longer legs than females. Six types of sensilla were observed on antennal terminal lobes. The total number of sensilla on the inner surface of terminal antennal lobes was larger in males than in females. One type of sensilla showed a sex-specific size difference. Among individuals that were collected as third stadium larvae on Miyako Island, Okinawa, Japan and reared in the laboratory (nϭ527), three emerged as adults with asymmetrical antennae. One was found to represent a gynandromorph and the others were a male and a female with a deformed antenna.

Chemoreceptors of adult Mexican bean beetles: External morphology and role in food preference

The Mexican bean beetle, Epilachna varivestis Mulsant (Coleoptera; Coccinellidae), is an oligophagous insect that accepts leaves of soybean, Glycine max (L.) Merrill, as food but exhibits distinct preferences among varieties. It is believed that the basis for discrimination between the resistant PI 229358 and the susceptible cv. 'Williams' is chemical. By the ablation of chemosensilla on antennae, maxillary palpi, labial palpi, and foretarsi, followed with leaf disc preference tests, we found antennal and maxillary palp chemosensilla to be almost entirely responsible for Mexican bean beetles' discrimination between foliage of the resistant and susceptible genotypes. All appendages, and the epipharynx, were observed by scanning electron microscopy and, except for foretarsi, were found to bear several types of presumably olfactory and gustatory sensilla, which are figured and described. Since behavioral observations show that olfaction is usually sufficient to cause rejection of PI 229358, we conclude that olfactory sensilla mainly on antennae and maxillary palpi are critical in food discrimination in this system.
