Striking polymorphism among infertile helpers in the arboreal ant Gesomyrmex

Christian Peeters, Fuminori Ito, Decha Wiwatwitaya, Roberto A. Keller, Rosli Hashim & Mathieu Molet
Gesomyrmex (subfamily Formicinae) is a poorly known arboreal ant from the Oriental tropics. We sampled colonies in three localities (NE Thailand, peninsular Malaysia, and Sabah) and examined inhabitants of ten nests inside living branches. None of the nests had a reproductive dealate queen, indicating colonies are polydomous. We distinguished three sterile castes using discrete morphological traits, morphometry and total body size. Observations of behaviour are challenging in tree canopies, and we use functional morphology to...

Ants as dominant insect visitors of the extrafloral nectaries of sponge gourd plant, Luffa cylindrica (L.) (Cucurbitaceae)

Vivek Mohan Agarwal & Neelkamal Rastogi
The button-shaped extrafloral nectaries (EFNs) located on the bracts, bracteoles, calyces and leaves of cultivated sponge gourd plant, Luffa cylindrica, were visited by insects belonging to five different orders: Hemiptera, Diptera, Coleoptera, Hymenoptera, and Lepidoptera. Insects with biological-control potential recorded at the EFNs included ants, wasps and ladybird beetles. Ants, comprising ten species, constituted by far the most abundant group (84.44 ± 4.34 % of individuals) at the EFNs. Insect pollinators included honey bees, butterflies...

Queen polymorphism in Acanthomyrmex careoscrobis Moffett, 1986 in Peninsular Malaysia (Hymenoptera: Formicidae: Myrmicinae), with descriptions of hitherto unknown female castes and males

Aiki Yamada, Fuminori Ito, Rosli Hashim & Katsuyuki Eguchi
The present study presents biological observations on colony characteristics of Acanthomyrmex careoscrobis Moffett, 1986 in Ulu Gombak (Selangor, Malaysia), with redescription of the minor worker and descriptions of the hitherto unknown female castes and males. The colony of A. careoscrobis can produce both alate and ergatoid queens. Ergatoid queens may function as cheap secondary reproductive females, whereas it is at present unclear whether they engage in dependent colony foundation or not. Ergatoid queens have the...

From ant-catcher to author: editors’ advice to young myrmecologists

John R. Fellowes & Martin Pfeiffer
Asian Myrmecology is a journal created and edited for those studying ants in Asia. It was established not necessarily to become the top journal in its field, but primarily to support and serve those in its region: experienced ant researchers as well as beginners. Its editors and reviewers give generously of their time and expertise to make it work, and we believe Asian Myrmecology has played a role, like the International Network for the Study...

The exocrine system of Aneuretus simoni (Formicidae, Aneuretinae)

Johan Billen
This paper reviews the morphology of the 11 exocrine glands that we found in Aneuretus simoni workers. In comparison with their stingless sister group Dolichoderinae, the stinging A. simoni has a well-developed venom gland with long and slender secretory filaments. They also share the occurrence of Pavan’s gland as source of the trail pheromone, although this gland has a bilobed appearance in Aneuretus, while it only has one lobe in dolichoderine species. The intramandibular gland...

Ants as bioindicators of ecosystem health in Shivalik Mountains of Himalayas: assessment of species diversity and invasive species

Himender Bharti, Meenakshi Bharti & Martin Pfeiffer
The Northern-Indian Shivalik mountain range has recently come under strong anthropogenic pressure. Ants were used as bioindicators to assess ecosystem health of the area. We measured diversity, community patterns, species composition and the influence of invasive species of Formicidae by collecting at 75 sites from 44 locations in three habitats: primary forest (PF), secondary forest (SF) and non-forest areas (NF) using six collection techniques. We obtained the most comprehensive dataset compiled for Indian ants to...

Provisioning services from ants: food and pharmaceuticals

Neelkamal Rastogi
The present review assesses the role of ants in providing ecosystem provisioning services in the form of products such as food and medicine. Many species of ants constitute an inexpensive, protein- and mineral-rich, unconventional human food source. Some ant species are also utilised in traditional entomotherapy by indigenous people, or as a complementary and/or alternative medicine, in many parts of the world. Recent biochemical and pharmacological investigations are increasingly providing evidence regarding the medicinal significance...

Ant diversity in a Peninsular Malaysian mangrove forest and oil palm plantation

Nor Rasidah Hashim, Wan Faridah Akmal Wan Jusoh & Mohd Nassrul Safre Mohd Nasir
In Malaysia, it is a common practice to convert mangrove forests into agricultural plantations, especially oil palm. For this to happen, mangroves are drained and pesticides and fertilizers are often used to encourage healthy growth and yield of the oil palms, impacting biodiversity there and nearby. Mangroves are challenging habitats and certain mangrove ants, such as the Australian species Camponotus anderseni, show a high degree of adaptation to them.
