“…On the other hand, the faeces of T. guasayana elicit assembling behaviour in larvae of T. sordida, but the inverse is not true: faeces of T. sordida do not promote the aggregation of T. guasayana larvae. Cruz-López et al (1993) obtained comparable results in their analysis of the aggregation of T. mazzottii, T. longipennis, T. pallidipennis, T. barberi and R. prolixus. The named authors postulated the existence of an "interspecific aggregation pheromone" that would be present in the faeces of larvae and adults of these species.…”

The response to intra-and interspecific assembling signals was tested in three species of Chagas' disease vectors. As previously described for Triatoma infestans, larvae of both species, T. sordida and T. guasayana, aggregated on papers impregnated with their own excrement. Moreover, bugs belonging to each of the three species also aggregated on papers contaminated with faeces from the other two, with the only exception of the larvae of T. guasayana, which did not assemble on faeces of T. sordida. In all cases, the response to interspecific excrement was as strong as that to the intraspecific one. The nonspecificity of the signal is discussed in the context of the ecological association of the three species and their role as vectors of Chagas' disease.

“…Although some of them moved towards human housings and originated the present arrange of species and strains of the genus, the assembling mechanisms could have been conserved if it evolved earlier than the process of domiciliation. Cruz-López et al (1993) reported the existence of an interspecific assembling pheromone in the faeces of larvae and adults of T. mazzottii, T. longipennis, T. pallidipennis, T. barberi and R. prolixus. They showed that the faeces of the five species did not exhibit differences in attractiveness for the insects.…”

“…Aggregation behaviour, as a response to chemical signals, has been reported in several species of Triatominae (Velázquez Antich 1968, Baldwin et al 1971, Schofield & Patterson 1977, Ondarza et al 1986, Cruz-López et al 1993, Lorenzo Figueiras et al 1994). Schofield and Patterson (1977) have reported an assembly pheromone in the larval faeces of R. prolixus that attracts unfed larvae and arrests the locomotion of fed larvae.…”

Furthermore, Lorenzo Figueiras and Lazzari (1998b) showed that an aggregating substance is present in the dry faeces of T. infestans, T. sordida and T. guasayana, which acts both, intra-and interspecifically.…”

The response to intra-and interspecific faecal assembling signals was tested in Rhodnius prolixus. Papers impregnated with excrement of R. prolixus induced the aggregation of larvae of this species, but also of those of Triatoma infestans. However, faeces belonging to T. infestans were not able to assemble larvae of R. prolixus. On the other hand, there was no response of R. prolixus to putative chemical factors from their cuticle (footprints), in contrast to T. infestans. Results are discussed as related to the ecology of both species.

Chemoecology of Insect Eggs and Egg Deposition

This is the first book to focus on insect eggs since the publication , in 1981, of Hinton's comprehensive but somewhat amorphous Biology of Insect Eggs, and the only book that has attempted to pull together aspects of the chemoecology of the eggs and oviposition. The first six chapters comprise the section on chemoecology of eggs. Here, I think, the editors have had to struggle to bring together appropriate work, and some of the chapters seem tangential to the topic. The most relevant are those of Gillott, and Eisner and colleagues. Gillott describes the female accessory glands and brings together information on the glandular origins of different chemical products associated with oviposition and the egg. The chapter by Eisner and colleagues brings together the various studies, mostly their own, on the chemicals passed in spermatophores to the female and which subsequently are found in the eggs. This is the first time such a review has been attempted and it is informative, readable and well illustrated. The chapter by Blum and Hilker on Chemical Protection of Eggs is also central to the topic, but suffers from the fact that much of it simply describes the compounds present in adults that are possibly also present in eggs. However, two tables list the compounds that are known to occur in or on eggs and the diversity of formulae is well illustrated. Perhaps it is still too soon to write a really satisfactory account of this topic. The first chapter, by Trougakos and Margaritis, gives a detailed account of egg morphology and egg morphogenesis in Dros-ophila, about which most is known, with reference to the eggs of other species where possible. The last two chapters of this section deal with Brood Protection in Social Insects, by Ayasse and Paxton, and the Role of Microorganisms for Eggs and Progeny, by Kellner. Both are interesting chapters although the information on eggs is almost incidental. The last seven chapters are devoted to the chemoecology of egg deposition. Whether egg deposition is different from oviposition never became clear to me, but that is trivial. Here there is no shortage of material. The first chapter, by Sta¨dlerSta¨dler, is a good survey of the role of plant chemical cues used by insects for locating and identifying host plants. It also includes a brief account of the sensory physiology involved in the perception of chemical cues. This is followed by a most interesting chapter by Hilker and her colleagues entitled The Plant's Response towards Insect Egg Deposition, including the induction of galls. Then comes a review by Anderson of oviposition marking phero-mones in herbivorous and carnivorous insects. Carnivorous, here, refers mainly to Hymenopteran parasitoids, but includes predaceous larvae of coccinellids and chrysopids. Subsequent chapters by McCall, and by Steidle and van Loon consider the chemoecology of oviposition site selection by insects of medical and veterinary importance and by parasitoids and predators, respectively. All these chapters are, rightly, largely descriptive and lack...
