“…In conclusion, this extraordinary specimen contradicts the exceptional view of Naisse (1966a) on the regulation of wing dimorphism and sexual differentiation by a male sex hormone. Rather, it supports the current views on the control of these morphogenetic processes.…”

“…This, however, does not apply in the case of L. noctiluca. Females undergo pupation and the female beetles, although wingless, present adult characteristics (Naisse, 1966a). The question as to the physiological, i.e., hormonal, control of winglessness has been addressed in Gryllidae (Zera et al, 1989;Cisper et al, 2000) and the planthopper Nilaparvata lugens (Ayoade et al, 1996(Ayoade et al, , 1999.…”

“…The specimen introduced here bears wings (although crippled) on the left side, whereas they are totally absent on the right side. If the finding of Naisse (1966a) is correct, i.e., that wing formation is also controlled by the apical testis tissue, the wing-bearing side should contain a testis, at least a rudimentary one. Thus, the described specimen presents a challenge to the long-standing statements of Naisse.…”

“…Davydova (1967) examined the role of juvenile hormone (JH) in wing formation during metamorphosis, and in a series of investigations Naisse (1966aNaisse ( -c, 1969 analyzed the endocrine control of the differentiation of primary and secondary sexual characteristics. According to Naisse (1966a), L. noctiluca represents a unique case in the direction of sexual differentiation among insects. Up to the third larval instar (L3) the structure of gonads and external morphological features cannot be distinguished between the sexes.…”

Case of unilateral wing formation in the female of the glowworm Lampyris noctiluca

On July 27, 1999, the first author found a unilaterally winged adult glowworm in a park in the city of Mainz. Except for the wings on the left side, the specimen exhibited female characteristics that extended to external sexual appendages, the lantern and the gonads. The internal organization showed some remarkable differences between right (wingless) and left (winged) side. The right ovary contained three times more mature eggs than the left side and the volume of the corpus allatum of this side was about one-third larger than that of the left side. This suggests that aptery and egg maturation are affected by corpus allatum activity, i.e., juvenile hormone production. The findings do not support the hypothesis of Naisse ([1966] Arch Biol Liège 77:139-201) that wing formation, as a secondary male characteristic, is controlled by an androgenic hormone from the testes in the glowworm. Thus, the observations on this exceptional specimen have implications for the current hypotheses concerning the control of sexual wing dimorphism in Lampyris noctiluca.

“…I n some cases, however, humoral factors have been found to affect sexual differentiation. I n the glow-worm Lampyris noctilrrca (Naisse, 1966) implantation of a mesodermic tissue from the testicular follicle in a female larva determines total or partial masculinization. Well known are also many cases of partial sexual reversal following destruction of the gonads by parasites (parasitic castration; Wigglesworth, 1970).…”

On the control of a sexual character in the aphidAcyrthosiphon pisum: the sex pheromone glands of oviparous females

In Acyrthosiphon pisum the tibial plaques, through which sexual pheromones are released, form one of the distinguishing features of the male-ovipara bixesual pair. They are very abundant in oviparae but completely absent in both males and virginoparae. In a third, rare, category of females which bear a mixed ovary containing both viviparous and oviparous ovarioles, these plaques may still be present but in reduced numbers. A correlation between the number of tibial plaques and that of viviparous and oviparous ovarioles in the ovaries has been found, suggesting that the morphogenesis of this character may be under ovarian control.

Structure of the apical cells of the testis of the tenebrionid beetles: Tenebrio molitor and Zophobas rugipes

The developmental cytology of the apical tissue of the testis of Tenebrio nzolitor and Zophobas rugipes was studied with light and electron microscopy. In the early larvae of both species the tisue was found to be a thickened protrusion of nongerminal cells appearing at the apical end of each testis follicle following gonadal differentiation. The cells persist through pupal and adult stages in both species, becoming more prominent at these stages in Z. rugipes, despite tracheal invasion in both species. In older adults the apical tissue regresses and ultimately distintegrates.Ultrastructurally the apical cells are distinguished from adjacent germinal cells by their (1) small, rounded or oval nuclei, (2) highly convoluted plasma membrane, ( 3 ) electron-opaque cytoplasm, (4) profuse concentrically-stacked, granular endoplasmic reticulum, ( 5 ) large aggregates of glycogen-like granules, (6) numerous small, tubular mitochondria, ( 7 ) well-developed Golgi centers and ( 8 ) striking arrays of microtubules. These cells have many cytological features in common with the androgenic gland cells of crustaceans, but not with the steroidogenic cells of vertebrates. Evidence for the formation of protein granules is also lacking. As yet, experimental procedures have not indicated an endocrine function for these cells in tenebrionids. However, their cytology is consistent with secretory activity of some kind.The apical tissue of the insect testis consists of a group of cells, or a single cell with abundant cytoplasm, situated at the apex of each testicular follicle. During the early part of this century (see Carson, '45; Aboim, '45, for reviews) much attention was paid to the cytology of the apical cells, and several hypotheses were presented as to their origin, function and fate. In most insects examined the apical cells were considered to be larval structures. Recently, Naisse ('65) has analogized the apical cells of a coleopteran Lampyris noctiluca with the androgenic gland of crustaceans. In Lampyris implantation of the larval testis at a critical stage into a female larva will completely transform the sex of the genetically female host at primary, secondary and behavioral levels. Naisse attributes the sex reversal to a hormone secreted by the apical cells, under the control of neurosecretory cells of the pars intercerebralis of the male larval brain (Naisse, '65).This important experimental finding and the absence of any ultrastructural information on the apical cells prompted this study of the fine structure of these cells in two tenebrionid beetles : Tenebrio molitor and Zophobas rugipes. The apical tissue of Tenebrio molitor had been described as early as 1902 by Demokidoff; however, he called the tissue a "lens" and claimed that it was different from the apical cells (of Verson) seen in other insects. Edwards ('61) comments similarly on the "lens" in another coleopteran, the cerambycid Prion,oplus.In the present study attention is directed a t changes in the apical cells during larval development, and to a com...
