“…; Brown and Cramer 1999), serrated plates (such as those present in several Pieridae) or relatively large structures covered by spines (such as that of Zamagiria sp. ; Iruegas et al 2002). A comparative phylogenetic study of this hypothesis would test for correlated evolution of potentially damaging signa and cornuti whose structure is appropriate for protecting the vesica.…”

The genitalia of many male insects include structures whose functions are unknown or poorly understood. The endophallus of many Lepidoptera bears sclerotized structures known as cornuti, which in some species break off during copulation and remain within the female genital tract ("deciduous" cornuti). I describe previous and original hypotheses on the role of cornuti, identify the selective pressures invoked by these hypotheses, propose different ways of testing them and briefly review pertinent evidence. I describe ten functional hypotheses for non-deciduous cornuti and four for deciduous cornuti; six hypotheses invoke natural selection and eight involve sexual selection. In some cases more than one of the proposed functions could be performed by cornuti; evolutionary change from one function to another is also possible. I suggest that the wide morphological variation observed in non-deciduous cornuti across taxa supports hypotheses invoking sexual selection. I propose that the function and evolution of cornuti can be revealed with a combination of descriptive studies, cornuti removal experiments and comparative tests.

“…Zamagiria dixolophella Dyar (Lepidoptera: Pyralidae), the sapodilla bud borer, is found in Mexico, Central America, and possibly South America (Heinrich 1956;Iruegas et al 2002). Sapodilla fruit in the Soconusco region of Chiapas are attacked by this moth, which is considered an important pest by local producers (Iruegas et al 2002).…”

“…The females lay eggs on the sapodilla branch shoots and the larvae feed on the shoots, flower petals, and occasionally on the fruits. Infestation persists throughout the year although the population peak coincides with the peak sapodilla flowering period between Mar and Jun (Iruegas et al 2002). Currently, control of this species is based on the use of insecticides.…”

Para imaturos de insetos fitófagos, a planta hospedeira representa um abrigo contra condições abióticas adversas, inimigos naturais e, ao mesmo tempo, seu recurso alimentar (Southwood 1973). A maioria dos insetos que se alimentam de plantas são oligófagos, utilizando espécies de um mesmo gênero ou família, mas não raramente existem espécies que são monófagas, isto é, utilizam somente uma espécie de planta hospedeira (Ehrlich & Raven 1964), o que torna muito importante o conhecimento de suas plantas hospedeiras.No Brasil, os registros de plantas hospedeiras de insetos fitófagos e informações de sua biologia e comportamento têm como fonte principal estudos pontuais ligados a alguns táxons de insetos, em geral, relacionados a pragas agrícolas ou Composição, abundância e notas sobre a ecologia de espécies de larvas de lepidópteros associadas a cinco espécies de plantas hospedeiras no Parque Nacional da Restinga de Jurubatiba, RJ . Thirty two species of Lepidoptera were reared from these five host plants, and the most abundant four species belonged to the Elachistidae. Manilkara subsericea showed the greatest number of Lepidoptera species associated, 14 species, followed by E. ovalifolium (10 species), P. icicariba (seven species), E. subsessile (six species) and P. heptaphyllum (two species).Only one out of the 32 species of Lepidoptera was gregarious and 56% used any kind of shelter to get food or for defence. Six Lepidoptera species (27%) were polyphagous, three (14%) oligophagous and 13 (59%) had just only one host plant species recorded. The most abundant species of moths exhibitted two reproductives periods in the year, predominantly in winter and autumn. Abiotic factors, such as strong insolation during spring and summer in the open scrub vegetation of restinga, may be very important in producing this temporal pattern of insect reproduction, but we cannot neglect biotic factors like natural enemies.
