“…T h e accessory gland is composed of 16 pairs of tubules, of which tubule I is called the opalescent gland (Odhiambo, 1969). Only the opalescent gland or the spermatophore (sperm packet) were active in stimulating oviposition, therefore a substance is transferred to the female through the spermatophore during mating (Lange & Loughton, 1985).…”

Summary Modern studies of chemical ecology and behaviour of the locusts Schistocerca gregaria and Locusta migratoria in the laboratory need to be more closely coupled with field experiments and observations. The life history relating to oviposition, transformation to gregarious phases, and adult maturation mediated by pheromones is reviewed. The principles of pheromone isolation and identification are discussed. The long‐term effects of the gregarization pheromone on the physiology are presented, with discussion of morphological changes, chiasma frequency increases, and synchronization of moulting induced by the pheromone. Isolation of the purported gregarization pheromone, locustol, from faeces is discussed in regard to inconsistent effects. Other more immediate effects of the pheromone on the social (gregarious) behaviour and the isolation of possible pheromone components different from but related to locustol are presented. It is stressed that more rigorous isolation studies should be undertaken to resolve conflicting reports and methodological problems. The possibility of an anti‐gregarization pheromone or solitarizing pheromone is discounted. The source and biosynthesis of locustol (or gregarization pheromone) from degradation of lignin by symbiotic bacteria is discussed. Theories of reception of the gregarization pheromone such as inhalation through the spiracles or sensory perception by the antennae are presented. Also an internal mechanism involving cAMP and/or corpora allata may be induced by gregarization pheromone to effect the physiological phase changes. The advantages to an individual of reception of the gregarization pheromone from a group of gregarious and pre‐migrating locusts is discussed. Also the possible benefits of gregarious behaviour, phase polymorphism and migration are dealt with. An adult (sexual) maturation pheromone has long‐term effects on reducing the period of maturation, and immediate effects on the behavioural vibration response. The epidermal source of the pheromone and glandular cells responsible for the production of the pheromone are discussed. The reception and internal mechanisms of response via the corpora allata are mentioned. The benefits to individuals of synchronized and rapid adult maturation in a gregarious group are considered. An oviposition‐stimulating pheromone produced by the male accessory reproductive glands appears to be a proteinaceous substance of large molecular weight. On the other hand, an oviposition‐aggregating pheromone volatilizes from epidermal areas of either sex and causes higher oviposition rates in the area of release. The behavioural and ecological aspects of this pheromone are discussed. Several other possible pheromones and semiochemicals are discussed, such as a long‐range sex pheromone, sex‐recognition pheromone, grass odours and feeding stimulants and deterrents. Several possible control strategies using locust pheromones are considered. The general conclusion is that the chemical isolation of the various pheromones is necessary before fur...

“…Histological and histochemical observations reported in a previous paper (Odhiambo 1969 a) have shown that intense secretory production in the locust ARGs is largely confined to the distal half of the glands, while the proximal half seems to be concerned principally with storage. Thus, although the prevalence of septate desmosomes along the intercellular spaces of these glands may imply more or less free intercommunication between adjoining cells, there seems to be another factor or factors that impose a gradient in the secretory processes of the glandular epithelium.…”

“…The histology and histochemistry of the accessory reproductive glands (ARGs) of the desert locust has been reported in a previous paper in this series (Odhiambo 1969a). It appeared from this study that the accessory gland complex consisted of nine types of glands, segregated vertically by the characteristics of their secretions and the cytological features of the various glandular epithelia.…”

The male desert locust, Schistocerca gregaria , has two masses of thin glands, each mass containing 16 glands. The glands in each mass are arranged in a precise manner, which is a mirror image of the arrangement to be found in the other gland mass. They produce secretions which participate in the production of the spermatophore and most of its contents during mating. The fine structure of these glands is described in detail on the basis of an electron-microscope study of sectioned glands and their secretions. It is revealed that the characteristics of the glandular epithelia and their corresponding secretions lead to the division of the accessory glands into nine distinct types. This finding strengthens the recent division of the glands into nine types based on histological, histochemical, and phase-contrast features. One gland produces a proteinaceous, crystalline secretion (gland 1), three types of glands produce a minutely fibrous secretion (glands 2 and 4, and ‘homogeneous’ glands), three other gland types produce a globular secretion (glands 6, 11 and 12), and one gland type has a lipoid secretion (gland 3). Gland 16, the functional seminal vesicle, does not produce a recognizable secretion. The cytoplasmic organelles that are concerned in the secretory process, and the manner in which their development varies with each gland type, are discussed.

“…The accessory glands of G. sigillatus consist of six groups of tubules in different color and sizes (Nandchahal, ). The characteristic of the glandular epithelium and the secretion divides the male accessory glands of the desert locust, Schistocerca gregaria (Forskål, 1775) (Orthoptera, Acrididae) into nine different groups (Odhiambo, ). The accessory glands in male P. cervus are composed of a large number of tubules in different lengths and divided into two groups.…”

The accessory glands of male reproductive system in insects play a significant role in the reproduction process by protecting sperm in spermatheca, preventing female to accept other males after mating and stimulating oviposition. The number, structure, and arrangement of the tubules of accessory glands can change from species to species. In this study, the accessory glands belonging the male reproductive system in Pseudochorthippus parallelus parallelus (Zetterstedt, 1821) (Orthoptera, Acrididae) were examined with stereomicroscope, light microscope, scanning (SEM), and transmission (TEM) electron microscopes at Gazi University, Faculty of Science in 2017–2019. P. parallelus parallelus is a widespread species that is located at the extending areas from Italy to the Northern Europe and also in Turkey. The accessory glands of P. parallelus parallelus’ male reproductive system are composed of about 10 tubules. The tubules can be classified into two groups according to the thickness of their muscle tissues. Both groups have single layered epithelial cells with mitochondria, well‐developed endoplasmic reticulum, spherical nucleus with electron dense chromatin, secretory vesicles and multivesicular bodies in their cytoplasm. In addition, apocrine type secretion is seen in epithelial cells.
