We report on the presence of scale mites (Trombidiformes: Pterygosomatidae) parasitizing three species of lizards in Timor-Leste. Geckobia bataviensis Vitzthum, 1926 was found associated with the Common House Gecko, Hemidactylus frenatus Duméril & Bibron, 1836, and the Indopacific Tree Gecko, Hemiphyllodactylus typus Bleeker, 1860, whereas Pterygosoma dracoensis Jack, 1962 was found on the patagia of a Timor Flying Dragon, Draco timoriensis Kuhl, 1820. The association of G. bataviensis with H. frenatus was well documented previously, but this is the first properly documented record of this mite for Timor-Leste. Our report of G. bataviensis on H. typus is the first association of this mite with this gecko. This is the second report of P. dracoensis on D. timoriensis and the first for Timor-Leste.

Common House Gecko (Hemidactylus frenatus) is one of reptiles that have ability to autotomy their tails. Tail autotomy is a mechanism to protect it self from predators. After the tail broke, there will be wound healing on the tail which is then followed by a tail regeneration event. Original tail and regenerate tail is very different morphologically and anatomically. The original tail is composed of bones while the tail of the regenerate is composed of cartilage. Histochemical staining using Alizarin Red-S Alcian Blue was done to differentiate bone and cartilage. This method will stained bones red while the cartilage will stained blue.

Hemidactylus Frenatus

Dehydration and hypersalinity challenge non-marine organisms crossing the ocean. The rate of water loss and saltwater tolerance thus determine the ability to disperse over sea and further influence species distribution. Surprisingly, this association between physiology and ecology is rarely investigated in terrestrial vertebrates. Here we conducted immersion experiments to individuals and eggs of six lizard species differently distributed across Taiwan and the adjacent islands to understand if the physiological responses reflect the geographical distribution. We found that Plestiodon elegans had the highest rate of water loss and the lowest saltwater tolerance, whereas Eutropis longicaudata and E. multifasciata showed the lowest rate of water loss and the highest saltwater tolerance. Diploderma swinhonis, Hemidactylus frenatus, and Anolis sagrei had medium measurements. For the eggs, only the rigid-shelled eggs of H. frenatus were incubated successfully after treatments. While, the parchment-shelled eggs of E. longicaudata and D. swinhonis lost or gained water dramatically in the immersions without any successful incubation. Combined with the historical geology of the islands and the origin areas of each species, the inferences of the results largely explain the current distribution of these lizards across Taiwan and the adjacent islands, pioneerly showing the association between physiological capability and species distribution.

The research about types of natural enemies of stinless bees Lepidotrigona terminata had been conducted in West Java. All natural enemis were identified morphologically and their habitat. There were 687 individuals of 14 species of  natural enemies obtained in this research, i.e., Pseudeuophrys sp., Heliophanus sp., Argiope versicolor, Plexippus paykuli, Marpissa sp., Parasteatoda tepidariorum, Tegenaria sp., Nasutitermes javanicus, Paratrechina sp., Polyrhachis sp., Paratrechina longicornis, Rhynchium haemorrhoidale, Hemidactylus frenatus and Hemidactylus garnotii. Based on observation, spider, ants, and lizard were the predators of stingless bee. The results are expected as data and knowledge in the conservation and cultivation of stingless bees.

Life cycle studies of Paradistomum geckonum (Dicrocoeliidae) were attempted experimentally. The pulmonate gastropod Lamellaxis gracilis served as the first intermediate host; geckonid lizards (Cosymbotus platyurus, Gehyra mutilata, and Hemidactylus frenatus) served as definitive hosts. The life cycle of Mesocoelium sociale (Mesocoeliidae) was studied in naturally infected first intermediate hosts (L. gracilis, Huttonella bicolor) and experimentally in geckonid definitive hosts (C. platyurus, G. mutilata, and H. frenatus). Some naturally infected L. gracilis were infected concurrently with larval stages of both digeneans. Second intermediate hosts, presumed to be arthropods, were experimentally unnecessary. Metacercariae of P. geckonum were not found. Cercariae of M. sociale formed encysted metacercariae in the same individual snails.

Hemidactylus Frenatus

Despite its success as an invasive species, little is known about the ecological aspects of the gekkonid lizard Hemidactylus frenatus in Colombia. In the present study the size at maturity, sexual dimorphism, reproductive activity, and diet composition of a population of this species in an urban locality of Northern Colombia were determined. We conducted eleven samplings from September 2011 to August 2012 in buildings of the municipality of Sincelejo. A total of 264 specimens H. frenatus were captured, 112 were adult females, 133 adult males and 19 juveniles. Males reach sexual maturity at a smaller size (snout-vent length) than females (males: 35.7 mm; females: 42.7 mm), also they are larger and have proportionally larger heads and mouths than females. Males were reproductive throughout the year; although testicular volume varied significantly between samples, this variation was not associated with body size and precipitation in the study area. Reproductive adult females were found during all the sampling period. Females have an invariable clutch size of two eggs and we found no differences in the diameter and weight of eggs in each oviduct. The diet of H. frenatus is varied, with Diptera, Hemiptera and Formicidae being the prey types with the greatest relative importance values. Individuals of both sexes consume a similar volume and number of prey. Thus, the studied population of H. frenatus has continuous reproductive activity and a generalist-opportunistic feeding behavior. The climatic conditions of the study area, environmental availability of prey and intrinsic features of this species appear to be responsible for their abundance and colonizing success in this and other localities.

Abstract Microhabitat orientation and structure and the presence of conspecifics may strongly influence the choice of habitat. We studied how these variables influence retreat- and nest-site selection in gravid females of a globally successful invasive species, the Asian house gecko (Hemidactylus frenatus). When provided with various substrates (vertical and horizontal ceramic tiles, vertical and horizontal plywood tiles, horizontal bark over leaf litter, vertical bark over a log, and sand) gravid female geckos preferred to retreat to, and nest in, materials with crevices commonly found in urban habitats. When housed alone, gravid females most frequently retreated to vertical ceramic tile or wooden crevices, and 66.7% nested in vertical ceramic tiles. When housed with two other conspecifics, gravid females most frequently retreated to vertical ceramic tiles, but selected a wider range of nest sites. Overall, gravid geckos housed alone typically nested in the same substrates that they used as diurnal retreats; when housed in groups, however, females oviposited in locations different from those they selected as retreats. Thus, H. frenatus females use a wider range of substrates when conspecifics are present. Invasion success in this species might be driven, in part, by preferences for retreat and nest substrates that are common in human-dominated habitats.
