Moths Behaving like Butterflies. Evolutionary Loss of Long Range Attractant Pheromones in Castniid Moths: A Paysandisia archon Model

BackgroundIn the course of evolution butterflies and moths developed two different reproductive behaviors. Whereas butterflies rely on visual stimuli for mate location, moths use the ‘female calling plus male seduction’ system, in which females release long-range sex pheromones to attract conspecific males. There are few exceptions from this pattern but in all cases known female moths possess sex pheromone glands which apparently have been lost in female butterflies. In the day-flying moth family Castniidae (“butterfly-moths”), which includes some important crop pests, no pheromones have been found so far.Methodology/Principal FindingsUsing a multidisciplinary approach we described the steps involved in the courtship of P. archon, showing that visual cues are the only ones used for mate location; showed that the morphology and fine structure of the antennae of this moth are strikingly similar to those of butterflies, with male sensilla apparently not suited to detect female-released long range pheromones; showed that its females lack pheromone-producing glands, and identified three compounds as putative male sex pheromone (MSP) components of P. archon, released from the proximal halves of male forewings and hindwings.Conclusions/SignificanceThis study provides evidence for the first time in Lepidoptera that females of a moth do not produce any pheromone to attract males, and that mate location is achieved only visually by patrolling males, which may release a pheromone at short distance, putatively a mixture of Z,E-farnesal, E,E-farnesal, and (E,Z)-2,13-octadecadienol. The outlined behavior, long thought to be unique to butterflies, is likely to be widespread in Castniidae implying a novel, unparalleled butterfly-like reproductive behavior in moths. This will also have practical implications in applied entomology since it signifies that the monitoring/control of castniid pests should not be based on the use of female-produced pheromones, as it is usually done in many moths.

Fine Structure of Antennal Sensilla of Paysandisia archon and Electrophysiological Responses to Volatile Compounds Associated with Host Palms

et al. 2015

Paysandisia archon (Lepidoptera: Castniidae) is a serious pest of palm trees. A comprehensive knowledge of the insect olfactory system is essential for the development of efficient semiochemical-based control methods. The olfactory sensilla are located particularly on the antennae, and these can detect plant volatiles that provide important cues for the insects in the search for their host plants. To date, the fine structure of P. archon antennal sensilla studies and their role in host-plant perception have not been investigated in great detail. Using light microscopy and scanning and transmission electron microscopy, the antennae of both sexes of P. archon are described here in detail, according to the different types, quantities and distributions of the sensilla. Six types of sensilla were identified. The most widespread are sensilla trichoidea, sensilla basiconica and sensilla auricilica, which are associated with olfactory function. These have cuticular shafts characterised by numerous pores, and they are innervated by two or three sensory neurons. Sensilla coeloconica, sensilla chaetica and sensilla ampullacea are associated with olfactory or olfactory-thermoreception, mechano-gustatory, and thermo-hygroreception functions, respectively. Moreover, the role of P. archon antennae in locating of the host palms was evaluated using electroantennograms, to monitor responses to ester and terpene compounds previously identified as volatiles of damaged/fermenting palm tissues. P. archon showed responses to all of the synthetic chemicals tested, with greater responses in the females, providing a significant sex*dose effect. Among the compounds tested, ethyl isobutyrate elicited the strongest antenna responses. The fine structure of the cuticular and cellular components of the P. archon antenna sensory equipment is described for the first time. The results of this study form an important starting point and complement physiological and behavioural studies, to provide valuable information of practical importance for the development of efficient semiochemical-based control methods.

“…Very few reports have been found in the literature about the possible presence of sex pheromones in the Castniidae family and only concern those of females (Rebouças et al , 1999). It was not until 2012 that three putative male pheromones were reported for the first time from P. archon male wings (Sarto i Monteys et al , 2012).…”

28Butterflies and moths are subject to different evolutionary pressures that affect several aspects 29 of their behaviour and physiology, particularly sexual communication. Butterflies are day-30 flying insects (excluding hedylids) whose partner-finding strategy is mainly based on visual 31 cues and female butterflies having apparently lost the typical sex pheromone glands. Moths, 32 in contrast, are mostly night-flyers and use female-released long-range pheromones for 33 partner-finding. However, some moth families are exclusively day-flyers, and therefore 34 subject to evolutionary pressures similar to those endured by butterflies. Among them, the 35 Castniidae, also called 'butterfly-moths' or 'sun-moths', behave like butterflies and, thus, 36 castniid females appear to have also lost their pheromone glands, an unparallel attribute in the 37 world of moths. In this paper, we review the sexual communication strategy in day-flying 38 Lepidoptera, mainly butterflies (superfamily Papilionoidea), Zygaenidae and Castniidae 39 moths, and compare their mating behaviour with that of moth families of nocturnal habits, 40 paying particular attention to the recently discovered butterfly-like partner-finding strategy of 41 castniids and the fascinating facts and debates that led to its discovery. 42 43
