“…2). In their exposed position near the tip of a growing shoot, the nymphs are preyed upon by a diverse array of invertebrates such as predatory Hemiptera, syrphid fly larvae, coccinellid beetle larvae, spiders, and wasps (Wood, 1974(Wood, , 1976(Wood, , 1983Dowell and Johnson, 1986;McKamey and Deitz, 1996;Cocroft, 2002). Females defend their offspring by approaching the predator from their position outside the group, fanning their wings, and kicking with their hind legs (Wood, 1976(Wood, , 1983Dowell and Johnson, 1986;Cocroft, 1999b).…”

SYNOPSIS.Communication among members of a colony is a key feature of the success of eusocial insects. The same may be true in other forms of insect sociality. I suggest that substrate-borne vibrational communication is important in the success of group-living, herbivorous insects. I examine three challenges encountered by herbivorous insects: locating and remaining in a group of conspecifics; locating food resources; and avoiding predation. Studies of groups of immature treehoppers, sawflies and butterflies suggest that vibrational communication can be important in each of these contexts, enhancing the ability of these group-living herbivores to exploit the resources of their host plants.

ABSTRACT. CLADlSTIC ANALYSIS OF THE MEMBRACINAE GENERA (HEMIPTERA, Au· CHENORRHYNCHA, MEMBRACID!\E). Phylogeny for 23 Membracinae genera based on cladistic methodology is proposed. Five Hypsoprorini, two Aconophorini and sixteen Membracini genera were stlldied. The Hoplophorionini genera were also analysed. KEY WORDS. Hemiptera, AlIchenolThyncha, Membracidae, Cladistic analysis DIETRJCH & McKAMEY (1995) investigaram as relações filogenéticas dos gêneros de Membracinae e entre os resultados obtidos destacam: Trinarea Goding, 1929, como grupo-irmão de Hoplophorionini, Havilandia Dietrich & McKamey, 1995, como grupo-irmão de Aconophorini e, em conseqüência Membracini como táxon parafilético. Essas conclusões divergiam de alguns resu ltados preliminares que foram observados quando do trabalho de revisão dos gêneros de Hoplophorionini. Fundamentalmente, essas divergências são decorrentes da interpretação diferente que foi dada a alguns caracteres e pela inclusão de outros, até então não abordados e que, conjuntamente, foram determinantes na obtenção de uma nova topologia. As tíbias clavadas, observadas em Trinarea e Hop lophorionini, que foram consideradas como um caráter sinapomórfico para esses táxons, são aqui entend idas como estruturas não homó logas. O tamanho subigual dos tarsos que ancorou a hipótese de que Havilandia e Aconophorini eram grupos-irmãos, pode decorrer de eventos históricos diferentes mas com resu ltados finais semelhantes e assim sendo tem um poder de decisão pequeno, não podendo apenas neste caráter se sustentar uma hipótese de ancestral idade comum. Assim, rejeitam-se neste trabalho as hipóteses de re lação de parentesco anteriormente estabelecidas para Trinarea e Havilandia devido à reinterpretação dos caracteres que foram determinantes no estabe lecimento daque las hipóteses e pela inclusão de outros, anteriormente não abordados, e que conjuntamente apontam para uma hipótese de ancestrai idade comum para os gêneros de Membracinae, aqui proposto como táxon monofilético.

“…Among membracids, it is assumed that species showing maternal care during nymphal development are semelparous (Wood 1984(Wood , 1993aMcKamey and Deitz 1996;Lin 2006), while those genera that are iteroparous or at least moderately iteroparous show ant mutualism, i.e., nymphal tending by ants whereby ants obtain honeydew excreted by nymphs and nymphs obtain protection against natural enemies (Nikhat and Imtiaz 1979, Stegmann and Linsenmair 2002, Zink 2003a, Linares et al 2010. Moreover, Wood (1984) proposes that landscape constancy promotes iteropary in membracids.…”

Geographic and Genetic Variation in Feeding Preference for Chemically Defended Seaweeds

2003

Genetic variation in tolerance for seaweed chemical defenses among populations of marine herbivores is poorly described, either because few marine studies have addressed the issue or because the feeding preferences of populations of marine herbivores rarely differentiate. We address this using the polyphagous amphipod Ampithoe longimana (Crustacea), which commonly consumes, and lives on, terpene‐rich brown seaweeds in the tropical genus Dictyota. Previous work demonstrated that in areas where the amphipod and seaweeds overlap geographically, these chemically deterrent seaweeds provide the amphipod with spatial refuges from predation by omnivorous fishes that avoid consuming Dictyota. However, the amphipod's distribution extends northward of the seaweed's distribution, making this benefit of association unavailable to more northerly populations of amphipods. On average, populations sympatric with Dictyota have stronger feeding preference for Dictyota species and greater fitness when raised on Dictyota than do populations that are outside Dictyota's geographic endpoint. These results are consistent with the hypothesis that in areas where the amphipods co‐exist with Dictyota, selection favors amphipods that tolerate Dictyota's chemical defenses and thereby access its enemy‐free space. Amphipods allopatric with Dictyota are unable to tolerate Dictyota's chemical defenses, either because of selection, drift, or some mix of both forces. A trade‐off between preference for Dictyota and for the chemically distinct seaweed Hypnea musciformis is suggested by the finding that populations with high preference for Dictyota tended to have lower preference for Hypnea. However, this population‐level pattern appears to be the result of independent evolution and not a genetic trade‐off: an analysis of full‐sib families within a single population detected heritable variation in preferences for Dictyota and suggested this for Hypnea (although the latter was not statistically significant), yet no family‐level covariation was detected. Phylogeo‐graphic analysis of mitocondrial DNA and nuclear sequences indicates a strong historical break between populations sympatric with Dictyota and populations more than 500 km beyond Dictyota's geographic endpoint. The historical separation of these most northerly populations could have allowed a random accumulation of alleles to effectively degrade tolerance for Dictyota, although selection may also be responsible for the degradation.
