Abstract

Pollination service in agroecosytems depends on several factors, including the land management systems used by farmers. The using of variety of wild plans as refugia area are expected to be an alternative habitat for pollinators insect in plants: Ageratum conyzoides, Ageratum hostionum, Commelina difussa and Capsicum frutescens This research aims to know the composition of pollinators insect visit of refuge block and analyze their patterns in apple plantation Poncokusumo village Malang. Direct observations of insect pollinators diversity, community structure insect pollinators and abiotic factors in Poncokusumo village. were conducted on August 2012 to December 2013. Sampling was took place in each refuge block in four times observation at 07.00, 09.00, 12.00 a.m. and 3.00 p.m. Analysis of potential insect pollinators of apple blossoms as obtained from the importance and value of diversity index (Shannon-Wiener). Composition using Bray Curtis Index. Diversity index value of insect pollinators (1,26). The similarity between refuge block with Bray Curtis index of 0.93 %. Community structure of insect pollinators in refuge block dominated from genus Syrphidae (40) and Tabanidae (22). Analysis of environmental factors of temperature, humidity and light intensity on the abundance of insect pollinators found a negative correlation with the R-square value of 64,7 %.
