“…Our findings show instead that, on the basis of prey-capture behaviour, prey-choice behaviour and preferences, P. wanlessi is a mosquito specialist. Evidence of mosquito specialization has either been absent or highly limited in the many reports of predation on adult mosquitoes by other spiders, including other salticids, or in the reports of predation on juvenile mosquitoes by spiders from other families [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53]. Instead of simply eating mosquitoes, P. wanlessi has a remarkable capacity to make decisions based on attending to the prey's identity (i.e.…”

Paracyrba wanlessi is a southeast Asian jumping spider (Salticidae) that lives in the hollow internodes of fallen bamboo and preys on the larvae, pupae and adults of mosquitoes. In contrast to Evarcha culicivora, an East African salticid that is also known for actively targeting mosquitoes as preferred prey, there was no evidence of P. wanlessi choosing mosquitoes on the basis of species, sex or diet. However, our findings show that P. wanlessi chooses mosquitoes significantly more often than a variety of other prey types, regardless of whether the prey are in or away from water, and regardless of whether the mosquitoes are adults or juveniles. Moreover, a preference for mosquito larvae, pupae and adults is expressed regardless of whether test spiders are maintained on a diet of terrestrial or aquatic prey and regardless of whether the diet includes or excludes mosquitoes. Congruence of an environmental factor (in water versus away from water) with prey type (aquatic versus terrestrial mosquitoes) appeared to be important and yet, even when the prey were in the incongruent environment, P. wanlessi continued to choose mosquitoes more often than other prey.

“…Such pests may be better controlled where multitrophic diversity is higher. For example, recent research has shown that some spider species can prey heavily on mosquitoes that vector malaria or dengue and, in doing so, reduce their abundance 22 . In addition, parasitoids of various cockroach species, such as wasps that lay their eggs in cockroach egg cases, have been shown to be common in some homes 23 .…”

Biodiversity–ecosystem function relationships on bodies and in buildings

Biodiversity underpins the function of ecosystems. Here we discuss how biodiversity-ecosystem function theory could apply to our bodies and buildings, outline practical applications and call for further research.A key thrust of ecological theory and experiments over the past 100 years has been the study of the effects of biodiversity on ecological functions. Based on hundreds of studies we know that biological diversity can help to prevent species invasions 1 and make ecological systems more resistant to climate change fluctuations 2 and pathogen establishment 3 . Greater biodiversity can also lead ecosystems to be more productive or efficient 4 . Yet, this research has not been adequately translated to practical application. This is particularly true in the contexts most immediate to daily human lives, namely on bodies and in buildings.

“…em áreas rurais do Quênia. De fato, diversos trabalhos apontam insetos pertencentes à ordem Diptera como as presas mais comuns de aranhas-saltadoras (Guseinov 2004(Guseinov , 2005WeteRinGs 2014). Dessa forma, o comportamento de "snatching", nas condições descritas neste trabalho, apresenta relevância ecológica por se caracterizar como uma "alça" temporária na rede trófica, estabelecida somente quando formas juvenis de formigas encontram-se vulneráveis fora da colônia, nas eventuais realocações de ninho.…”

Comportamento Predatório Incomum de Menemerus bivittatus (Dufour) (Araneae, Salticidae)

Resumo. Neste trabalho, a aranha-saltadora Menemerus bivittatus (Dofour) é registrada como predadora de pupas de formigas Camponotus crassus Mayr. A captura desse tipo de presa foi realizada por meio da execução de um comportamento especializado, conhecido como "snatching". Aranhas que exibem esse comportamento roubam o material transportado por formigas operárias (presas ou formas juvenis) para se alimentar. No Brasil, registros desse tipo de interação são escassos na literatura. Trata-se do primeiro registro do comportamento "snatching" em ambiente urbano. Palavras-chave:Aranhas-saltadoras; Camponotus crassus; "snatching". Unusual Predatory Behavior of Menemerus bivittatus (Dufour) (Araneae, Salticidae)Abstract. In this work, the jumping spider Menemerus bivittatus (Dofour) is registered as a predator of pupae of the ant Camponotus crassus Mayr. The capture of this type of prey was performed by running a specialized behavior, known as "snatching". Spiders that exhibit this behavior steal the material transported by worker ants (prey or brood) to feed. In Brazil, records of this type of interaction are quite scarce. This is the first record of the snatching behavior in urban environment.
