FAKTOR-FAKTOR EKOLOGIS YANG BERPENGARUH TERHADAP STRUKTUR POPULASI KUMBANG BADAK (Oryctes rhinoceros L. )
Abstract: Rhinoceros beetle
(Oryctes rhinoceros L.) can live optimally with the support of a suitable
ecological factors. Ecological factors which include habitat waste organic materials
of vegetation, the natural enemies, the season, and the weather factors (such as:temperature,
rainfalls, and humidity) were investigated by their effects on the population
structure of the Rhinoceros beetle during October to December 2015. This study
is a survey of sampling which had been done four times, twice in the dry season
and twice in the rainy season. The data were analyzed with multivariate analysis,whereas
to determine the most ecological factors, it is needed a continued study by Duncan
test.
The results of multivariate analysis of variance abundance of each stage
of the rhinoceros beetle in some types of waste, season, temperature, habitat
temperature, humidity, and moisture habitat and their interactions showed that
the waste is a key ecological factor rhinoceros beetle larval development (P
<0.10).
The results of further analysis by Duncan test showed that the leaf
litter waste is a key factor for larval development (P <0.10), while the
interaction of temperature and humidity habitat influence pupal stage (P
<0.20). Results of multivariate analysis also showed that interaction
between the type of waste with humidity and moisture habitat; types of waste
with humidity; humidity humidity habitat with a variety of factors that affectmthe
interaction of the abundance of the rhinoceros beetle larvae stage (P
<0.10). The four factors that interact earlier showed important ecological
factors that work together in influencing abundance rhinoceros beetle grub.
Unlike the grub abundance, pupa stage rhinoceros beetle abundance is determined
by the interaction between the type of waste to the air temperature (P
<0.10), or in other words, the interaction between the type of waste to the
air temperature is a key factor in the development of rhinoceros beetle pupa
stage. Meanwhile, the interaction between temperature humidity habitat with
habitat; temperature and humidity habitat habitat as the sole factor refers to
the ecological factors that influence the development of rhinoceros beetle pupa
stage.
