As comunidades de formigas que vivem em fragmentos de Mata Atlântica rodeados por um ecossistema urbano bem desenvolvido, foram investigadas. Avaliou-se a riqueza, a freqüência de ocorrência das espécies bem como a similaridade entre três áreas da cidade de São Paulo: Parque da Previdência (PP), Reserva Florestal "Armando Salles de Oliveira" (CUASO) e Horto Oswaldo Cruz (HOC). Foram colocadas armadilhas do tipo "pitfall" em locais onde não ocorre visitação pública, durante uma semana, nos meses de março, junho, setembro e dezembro de 2001. Em todos os fragmentos foram coletadas 79 espécies de formigas, pertencentes a nove subfamílias e 32 gêneros. A subfamília Myrmicinae e os gêneros Pheidole e Hypoponera foram os mais ricos. No PP foram registradas 62 espécies, na CUASO 46 e no HOC 43, sendo que PP e CUASO são mais similares entre si. Tal similaridade possivelmente esteja relacionada ao tamanho de ambas as áreas e, também, a uma semelhança nos sítios de nidificação e de alimentação. No geral, a fauna de formigas é generalista, com a presença de alguns gêneros especialistas, como Discothyrea, Acanthognathus, Gnamptogenys, Oxyepoecus e Pyramica; ou de gêneros cujos hábitos alimentares ainda são desconhecidos (Heteroponera e Myrmelachista). A presença de espécies caracteristicamente de áreas domiciliares também foi constatada: Pheidole megacephala Fabricius, 1793, Linepithema humile Mayr, 1868, Wasmannia auropunctata Roger, 1863, Paratrechina fulva Mayr, 1862, P. longicornis Latreille, 1802 e Tapinoma melanocephalum Fabricius, 1793.

Tapinoma Melanocephalum

Tapinoma melanocephalum has a haploid number of 5, comprising four metacentrics and one acrocentric chromosome. T. sessile karyotypes (n = 8) comprise seven metacentric chromosomes and one that has acrocentric, subacrocentric and metacentric alternatives. In some haploid sessile preparations with acrocentric or subacrocentric chromosomes present, an acromatic gap, sometimes with an interstitial granule, is seen in the long arm of the non-metacentric.

Ant-hemipteran mutualism has been well documented, and many studies have reported the interference competition between ant species for the mutualism. However, little is known on how this interference competition impacts the reciprocally beneficial association. Previous studies demonstrated that the invasive mealybug Phenacoccus solenopsis (Tinsley) has established close mutual relationship with the ghost ant Tapinoma melanocephalum (Fabricius). The sympatric ants, Paratrechina longicornis (Latreille) and Tetramorium bicarinatum (Nylander) were frequently observed to compete for nutrient honeydew produced by P. solenopsis with T. melanocephalum. Herein, we investigated the effects of interference competition between the ant species on the ant-mealybug interactions. Phenacoccus solenopsis benefited from the tending by T. melanocephalum and P. longicornis. Interference competition between T. melanocephalum and P. longicornis interrupted the mutualism, suppressed the trailing activity of both species, but negligibly influenced the parasitism of Aenasius bambawalei Hayat, a solitary endoparasitoid of P. solenopsis. Harmonia axyridis, a predator of P. solenopsis, showed a significant avoidance when encountering with T. melanocephalum or P. longicornis, but not T. bicarinatum. Ant workers showed higher aggressiveness and lower exploratory activity when T. melanocephalum encountered P. longicornis. However, competition between T. melanocephalum and T. bicarinatum seldom influenced the trailing and exploratory activity of T. melanocephalum. It is concluded that interference competition for mutualism between ant species can mediate ant-mealybug associations and the fitness of mealybug colony. Our results also demonstrate that the effects of interference competition between ant species on ant-mealybug mutualism are varied among ant species.

A survey of structure-invading pest ants was conducted at 17 healthcare facilities (HFs) in Singapore using the index card method. A total of 18 species (Anoplolepis gracilipes (Fr. Smith), Meranoplus sp., Monomorium destructor ( Jerdon), Monomorium floricola ( Jerdon), Monomorium pharaonis (L.), Monomorium sp., Odontomachus sp., Oecophylla smaragdina (F.), Pachycondyla sp., Paratrechina bourbonica (Forel), Paratrechina longicornis (Latreille), Paratrechina pubens (Forel), Pheidole megacephala (F.), Pheidole parva (Mayr), Pheidole sp., Tapinoma indicum (Forel), Tapinoma melanocephalum (F.) andTetramorium bicarinatum (Nylander)) were trapped. Of these, the most common species were P. parva (25.9%), P. megacephala (25.2%), P. longicornis (14.1%), M. pharaonis (9.6%), and T. indicum (8.1%). Most of these ant species were found in and around the premises.
