preliminary study on insects associated with pig carcasses was conducted in Phitsanulok, northern Thailand. Five decomposition stages of pig carcasses were categorized: fresh (0-1 day after death), bloated (2 days after death), active (3 days after death), advanced (4- 6 days after death) and dry (7-30 days after death). The arthropod species collected from the corpses in the field sites were mainly classified belonging to two orders and nine families, namely order Diptera (family Calliphoridae: Chrysomya rufifacies and Chrysomya megacephala, family Muscidae: Musca domestica, family Faniidae: Fannia canicularis, family Sarcophagidae: Parasarcophaga ruficornis and family Piophilidae: Piophila casei,) and order Coleoptera (family Dermestidae: Dermestes maculatus, family Histeridae: Hister sp., family Cleridae: Necrobia rufipes and family Trogidae: Trox sp). The forensically dominant fly was C. rufifacies, while the beetle was D. maculatus. The beetles associated with pig carcasses found in this study are first reported in Phitsanulok, Thailand. In addition, ants, bees, spiders and millipedes were also associated with the carcasses. These findings may provide data for further use in legal investigations in Thailand.

Objective: To evaluate the efficacy of symbiotic bacteria, Xenorhabdus indica, Xenorhabdus stockiae, Photorhabdus luminescens subsp. akhurstii and Photorhabdus luminescens subsp. hainanensis as a larvicide against Aedes aegypti and Aedes albopictus. Methods: Larvae (L3-L4) of Aedes aegypti and Aedes albopictus were given 2 mL of a suspension 10
