“…Unlike relatedness, this is a minor problem since what matters is similarity proximity of less common key characters in the population among the individuals under consideration. This subject, well documented in the literature, reinforces the concept that recognition in social groups is phenotypic (Greenberg, 1979;Boch and Morse, 1982;Getz and Smith, 1983). However, for a newborn with no ability to discern its closest genetic relatives, such recognition must be comparative, i.e., in a given universe, among all similar individuals, some must be more similar than others.…”

Data on primitively social groups of Hymenoptera have been somewhat contradictory with respect to kin recognition, degree of relatedness and social evolution. This study presents a new concept of "relatedness coefficient". Called "aggregated relatedness", the hypothesis here introduced proposes that genes shared by any two individuals affect formation of family units to an extent dependent on their frequency and manner of dispersion in neighboring populations.
Dados de campo de espécies de Hymenoptera primitivamente sociais têm se mostrado contraditórios quanto ao papel do reconhecimento de parentes e do grau de parentesco na evolução social. Nesse trabalho um novo conceito de "coeficiente de parentesco" foi desenvolvido. Esta nova hipótese foi chamada de "parentesco agregado". Nesse conceito, genes compartilhados por dois indivíduos quaisquer têm importância significativa na formação das unidades familiares, dependendo de suas freqüências e da forma como estão distribuídos na população circunvizinha a esta unidade familiar

“…At present, field data on LMC and polyandry in social hymenoptera are rather scanty. Kin recognition has been repeatedly demonstrated (Greenberg 1979;Getz and Smith 1983;Breed 1981;Klahn and Gamboa 1983) but the ability to distinguish between full and half sisters within a single colony has not been demonstrated so far (Gadagkar 1985b). An empirical study designed to simultaneously gather quantitative information on sex investment ratios, LMC, multiple mating and kin recognition is now essential and well within the realm of possibility due to the increasing application of electrophoretic methods (Metcalf 1980).…”

Abstract. A model is constructed to study the effects of local mate competition and multiple mating on the optimum allocation of resources between the male and female reproductive brood in social hymenopteran colonies from the 'points of view' of the queen (parental manipulation theory) as well as the workers (kin selection theory). Competition between pairs of alleles specifying different sex investment ratios is investigated in a game theoretic frame work. All other things being equal, local mate competition shifts the sex allocation ratio in favour of females both under queen and worker control. While multiple mating has no effect on the queen's optimum investment ratio, it leads to a relatively male biased investment ratio under worker control. Under queen control a true Evolutionarily Stable Strategy (ESS) does not exist but the 'best' strategy is merely immune from extinction. A true ESS exists under worker control in colonies with singly mated queens but there is an asymmetry between the dominant and recessive alleles so that for some values of sex ratio a recessive allele goes to fixation but a dominant allele with the same properties fails to do so. Under multiple mating, again, a true ESS does not exist but a frequency dependent region emerges. The best strategy here is one that is guaranteed fixation against any competing allele with a lower relative frequency. Our results emphasize the need to determine levels of local mate competition and multiple mating before drawing any conclusions regarding the outcome of queen-worker conflict in social hymenoptera. Multiple mating followed by sperm mixing, both of which are known to occur in social hymenoptera, lower average genetic relatedness between workers and their reproductive sisters. This not only shifts the optimum sex ratio from the workers' 'point of view' in favour of males but also poses problems for the kin selection theory. We show that kin recognition resulting in the ability to invest in full but not in half sisters reverts the sex ratio back to that in the case of single mating and thus completely overcomes the hurdles for the operation of kin selection.

“…Indeed, kin recognition by scent is a hallmark of social insect communication [9]. This ability reaches its peak in (Received 22 March 1988) the honey bee in which workers are able to distinguish between patrilines in the hive [10,11]. The various levels of recognition via a pheromonal system obviously require a multicomponent pheromone.…”

. Abetract--The chemical composition of Dufour's gland secretions of 13 species of halictine bees was investigated. The secretions were composed of a series of macrocyclic lactones, hydrocarbons and isopentenyl esters. The number and relative intensities of these compounds were unevenly disu'ibuted among the species, i.e. the secretions were species specific. Based on the empirical date, an algorithm was constructed in order to assess how many of the components present in a secretion are required to discriminate between species, non-related conspecific individuals or nestmates. The results demonstrate that the number of components required for recognition increases with the increase in the level of specificity and with the number of individuals to be identified. The number of compounds denoting identity in a species specific blend may be surprisingly low. Using a similar technique, we assessed the number of components a secretion must contain in order to obtain individual recognition at different levels of relatedness. Several predictions regarding the level of recognition that can be attained by a given pheromone in a given population can be made from these theoretical results.
