Abstract

House dust mite (HDMs) may be found in urban dwelling and the existence of HDMs is influenced by temperature and relative humidity. The aim of the study was to evaluate the temperature and relative humidity effect the existence of HDM in Pamulang and Jakarta. There were 52 house dust samples from Pamulang and 44 from Jakarta examined by direct method using microscope to detect HDM in the dust samples. The temperature and relative humidity in the house were examined by thermohygrometer. The collecting of the samples was conducted 3 times with 2 weeks interval time. The species of HDM found were Dermatophagoides pteronyssinus, D.farinae, and Glyciphagus destructor. Statistically, the existence of HDM in 30-35oC was not significant different from that in < 30oC in both Pamulang and Jakarta (p<0.05). In contrast, the existence of HDM in relative humidity, 60-70%, was significant different from that in <60% in both Pamulang and Jakarta (p<0.05), especially in third sample collecting. It can be concluded that the existence of HDM was influenced by relative humidity, but not temperature in urban dwelling.

Abstract

Ability to infestation and abundance of parasitic mites in Aedes spp. larvae cannot be separated from the influence of various factors. Ecological factors have been suggested to play a role determine the presence of parasitic mites that under certain conditions become a key factor in determining the abundance of parasitic mites on Aedes spp. larvae. The aim of this study to determine the ecological factors affect the abundance of parasitic mites on Aedes spp. larvae in Bogor Regency. Capturing of Aedes spp. larvae was performed directly on the habitats found in indoor and outdoor. Capturing mites in the body of Aedes spp. larvae was performed using insect forceps. Ecological factors measured were dissolved oxygen (DO), pH, temperature, and total dissolved solid (TDS). The influence of ecological factors was analyzed using regression and correlation analysis. The result of mite identification has been obtained three species of mites that are Halacarus sp., Histiostoma sp., and Hydrozetes sp. The result indicated that total dissolved solid (TDS) and temperature was the factors that determined the abundance of mites. The factors of pH, and dissolved oxygen (DO) did not determine the abundance of parasitic mites of Aedes spp. larvae. The research result can be further developed as a new alternative to Dengue Hemorraghic Fever control and provide information on parasitic mites that infest Aedes spp. larvae. In addition, this results become an early step in controlling of Aedes spp. strategy platform by the parasitic mites.

Abstract

Livestock of broiler chickens using several types of cages, including the type of litter stage and litter postal. Treatment of chicken manure in both types of cages will cause the condition of the manure as the habitat of mite family Macrochelidae will be different. The diversity of mites family Macrochelidae are suspected to be different in manure found on stage litter cages compared to litter postal cages and influenced by some environmental factors. The aim of this study is to analyze the diversity of mites family Macrochelidae and its relation to environmental factors. The obtained manure sample was then taken to the laboratory and placed on a modified Barlese-Tullgren for mite isolation. The mites obtained are then counted, preserved, and identified at the Laboratory. Environmental factors measured are temperature and humidity. The diversity data obtained were analyzed using the Shannon-Wiener index and the Shannon-Evennes index. Pearson correlation test to determine the relationship between temperature and humidity to the diversity of mites of Macrochelidae family. Five species of mite Macrochelidae are Macrocheles sp.1, Macrocheles sp.2, Glyptholaspis sp., Neopodocinum sp., Holostaspella sp. The diversity index of mites family Macrochelidae on manure litter stage is 0.81354. The index diversity of mites on manure litter postal is 0.79871. The humidity factor influences the diversity of the mites of family Macrochelidae in both types of cages.
