“…The physiological costs of pheromone production are only beginning to become clear (Harari et al 2011;Harari and Steinitz 2013). Even less attention has been paid to the spatial distribution of females (McNeil 1991), how developmental environment affects calling, and how calling neighbors affect a female's calling behavior (Stelinski et al 2006). It is also unclear as to the relative transition between effects of long-range and short-range mate searching, because once males locate females, shortrange pheromones and acoustic cues may influence whether mating occurs (Birch et al 1990;Conner 1999).…”

“…It is also unclear as to the relative transition between effects of long-range and short-range mate searching, because once males locate females, shortrange pheromones and acoustic cues may influence whether mating occurs (Birch et al 1990;Conner 1999). Further, obviously all of these factors can be strongly influenced by the weather and climate (McNeil 1991;Pellegrino et al 2013), and mate-searching males are known to navigate pheromone plumes of rather complex filamentous structure (e.g., Liu and Haynes 1992). Females can simply modify male arrival rates by choosing not to call (e.g., after mating; Webster and Cardé 1984).…”

Although females rarely experience strong mate limitation, delays or lifelong problems of mate acquisition are detrimental to female fitness. In systems where males search for females via pheromone plumes, it is often difficult to assess whether female signaling is costly. Direct costs include the energetics of pheromone production and attention from unwanted eavesdroppers, such as parasites, parasitoids, and predators. Suboptimal outcomes are also possible from too many or too few mating events or near-simultaneous arrival of males who make unwanted mating attempts (even if successfully thwarted). We show that, in theory, even small costs can lead to a scenario where young females signal less intensely (lower pheromone concentration and/or shorter time spent signaling) and increase signaling effort only as they age and gather evidence (while still virgin) on whether sperm limitation threatens their reproductive success. Our synthesis of the empirical data available on Lepidoptera supports this prediction for one frequently reported component of signalingtime spent calling (often reported as the time of onset of calling at night)-but not for another, pheromone titer. This difference is explicable under the plausible but currently untested assumption that signaling earlier than other females each night is a more reliable way of increasing the probability of acquiring at least one mate than producing a more concentrated pheromone plume.

“…Diferenças na periodicidade de acasalamentos dos Lepidoptera em razão da idade podem ser explicadas por mudanças nos padrões temporais da síntese e liberação do feromônio sexual pelas fêmeas, assim como da resposta dos machos, em razão do estado fisiológico do inseto (McNeil 1991, McNeil et al 1996. Portanto, as maiores freqüências de acasalamento de L. coffeella nas idades de um e três dias estariam relacionadas com elevadas taxas de produção e liberação de feromônio sexual e com a maior receptividade e resposta dos machos aos estímulos da fêmea.…”

-Despite the importance of Leucoptera coffeella (Guérin-Mèneville) in coffee production worldwide, there is a lack of information on its reproductive biology. This knowledge will help in mass rearing, as well as support the development of behavioral control techniques for this insect. The purpose of the study was to determine the periodicity of mating and male capture and describe the mating behavior L. coffeella. In laboratory, we observed the periodicity of mating with virgin couples of different ages, zero to five days after emergence. Male activity was studied in a 0.7 ha coffee plantation, cv. Catuaí, where Delta traps were installed at 0.5 m above ground, using either virgin females or rubber septa lured with the synthetic sex pheromone. The sequence of mating behavior was studied by making visual observations and recorded of pairs placed on individual plastic tubes. Mating occurred between 4h and 6h of photophase, when the highest frequencies involved pairs with ages of one and three days after emergence, with peak of mating occurring in 5 th hour of photophase. The young or old pairs showed significantly copulation frequency and the peak of matings advance in 1h. The highest male capture occurred at 12p.m. and 13 p.m. by traps with virgin females or traps with synthetic sex pheromone lures, respectively. L. coffeella is one insect with diurnal mating and the mating behavior was not different from what is know for other Lepidoptera species.KEY WORDS: Reproduction, calling behavior, courtship, pheromone trap RESUMO -Leucoptera coffeella (Guérin-Mèneville) é praga-chave na cafeicultura; contudo, faltam informações sobre sua reprodução para o desenvolvimento de táticas de controle por comportamento. Este trabalho teve como objetivos determinar a periodicidade de cópulas; a periodicidade de captura dos machos e caracterizar o comportamento de acasalamento de L. coffeella. A periodicidade de acasalamento foi avaliada em laboratório com casais virgens de diferentes idades, zero a cinco dias após a emergência, individualizados em tubos transparentes. A periodicidade de captura foi avaliada em café cv. Catuaí, onde foram instaladas armadilhas Delta com dois atraentes: fêmeas virgens e septos de borracha impregnados com o feromônio sexual sintético. As etapas do comportamento de acasalamento foram descritas a partir de observação direta e de filmagens de casais virgens individualizados em tubos transparentes. Os acasalamentos ocorreram entre 4h e 6h da fotofase, onde as maiores freqüências envolveram casais com idades entre um e três dias da emergência, com pico de acasalamentos na quinta hora da fotofase. Os casais recém-emergidos ou velhos mostraram significativamente menor freqüência de cópulas e o pico dos acasalamentos antecipado em 1h. A maior captura ocorreu às 12:00h e 13:00h, nas armadilhas com fêmeas virgens e feromônio sexual sintético, respectivamente. Pelos resultados, L. coffeella é um inseto com acasalamento diurno e os comportamentos de chamamento e corte seguem o padrão encontrado em outr...

“…Estas variações tanto podem ser explicadas pela variabilidade genética, possivelmente por causa do isolamento geográfico das populações, bem como pelos fatores que afetam a resposta dos machos, tais como temperatura e umidade, planta hospedeira, idade das fêmeas e status reprodutivo (McNeil, 1991). Variações similares nas respostas dos machos entre populações isoladas geograficamente, ocorrem em outros lepidópteros e em alguns coleópteros (Cardé et al, 1978).…”

SYNTHETIC SEX PHEROMONE USE FOR FIELD TRAPPING OF DIAMONDBACK MOTH MALESABSTRACT -The aim of this work was to study the attractiveness of males of Plutella xylostella L.(Lepidoptera: Yponomeutidae) to different formulations of synthetic sex pheromone. The treatments were: 1) commercial formulation; 2) Z-11,16:Ald; 3) Z-11,16:Ac; 4) binary blends 7:3 of 2+3; 5) binary blends 5:5 of 2+3; 6) rubber septa with hexane (control); 7) five virgin females. The commercial formulation of the synthetic sex pheromone was more attractive to males, and did not differ significantly from virgin females and binary blends 5:5 treatments. The components alone were less attractive to males. Five traps were evaluated: Pherocon 1 CP (wing trap), Delta, "PVC 200", "PVC 250" and Black Round Trap, where the wing trap was more effective in capturing males than the other traps tested. The wing trap was evaluated at 5, 30 and 60 cm. More males were caught at 30 cm above the ground level, while the height of 5 and 60 cm did not differ significantly.
