“…Interestingly, L. botrana females exposed to synthetic pheromone after mating laid fewer eggs in the first 2 days after mating than control females, although overall productivity was not affected. L. botrana females typically lay one egg on a berry, which supplies enough food for the larva to reach pupation . Thus, a signal indicating the presence of a large population may indicate high competition for resources.…”

“…In general, butterflies assess egg-load on their host-plants either directly by vision (WIKLUND & AHRBERG 1978;SHAPIRO 1981;RAUSHER 1979) or chemically, through the presence of deterrent pheromones (SCHOONHOVEN et al 1990;THIERY & LEQUERE 1991;THIERY et al 1992). Heliconians are considered to have a good sense of vision, which includes color identification and associative learning (CRANE 1955;SWIHART 1971).…”

ABSTRACT. Oviposition response of Heliconius erato phyllis (Fabricius, 1775) (Lepidoptera, Nymphalidae) to variation in host plant availability, Passiflora suberosa Linnaeus (Passifloraceae), and to presence of conspecific eggs and larvae was determined through choice experiments performed under insectary conditions. Freeze dried, painted eggs and larvae were used as mimics for testing presence of con specific effects. Females laid more eggs on intactP. suberosa shoots without conspecifics than on those with H. erato phyllis egg and first instar mimics in both simultaneous and sequential choice trials. Oviposition response to variation in host plant availability was determined through no-choice trials, under host plant densities varying from 0.3 to 8.3 plants per female. Number of eggs laid per plant decreased exponentially with an increase in plant availability. On the contrary, daily oviposition rates (eggs /female/day) increased with an increase in plant number, and levelled off when the number of plants available for oviposition was greater than potential fecundity offemales. Thus, it is inferred from the results that females assess egg and larval load and prefer to lay eggs on shoots free from conspecifics. It is also inferred that they are able to recognize plant abundance and are unwilling to lay more than one egg per shoot even when host availability is scarce, as judged by reduction in daily oviposition rates under low host plant number. The consequences of laying isolated eggs on P. suberosa shoots are discussed from the viewpoint of intraspecific competition in the larval stage of H. erato phyllis. KEY WORDS. He/iconius, Passiflora, oviposition behavior, egg-load assessment, plant density recognition Oligophagous insects typically choose host-plants for oviposition, their larval hosts being indirectly determined through oviposition site selection. Their host-choices are based not only upon inter-specific plant attributes but also on variation within individual plants, as for example on host size, age and phenology. A close association is commonly found between host-plant species they choose from and performance regarding their survivorship, developmental rates and size attained in the larval stage. As a consequence, it has been inferred that host choices made by oligophagous insects are at least in part mediated by suitability of plant species, or 1) P6s-graduacao em Entomologia,

“…It was identified on the abdomen of the ant Lasius alienus (Bergstr6m & L6fqvist 1970). ML and MP were both identified as an oviposition-regulating pheromone in the butterflies Ostrinia nubilalis (Thiery & Le Quere 1991) and Lobesia botrana (Thiery et al 1992). Recently, it was shown that the methyl esters and the acids of these esters are also attractive for astigmatid mites (Sato et al 1993).…”

Summary. Honey bee workers are able to nurse or to destroy and thus to recognize the capped queen cells containing a pupa. Fatty acid esters, especially methyl oleate, methyl palmitate and ethyl oleate were found in significant amounts on the queen pupal cuticle. Methyl oleate, the major component, along with smaller amounts of methyl linoleate and methyl linolenate, were involved in the recognition of queen cells by workers. In natural conditions of the colony, queen cells containing a paraffin pupal lure with methyl oleate were accepted 5.9 days by workers, releasing about 1.8 queen pupa equivalents during that period, when control cells (without ester) were kept only 2.1 days. Although these esters are non specific to honey bees, they are of great importance in social regulation of the honey bee colony.
