Abstract

Spiders are crucial in controlling insect pest population. The various cultivation managements such as fertilizer and pesticide application, weeding, pruning, harvesting, and cropping system affect their diversity. In the plantation, vegetation diversification has applied various practices, including monoculture, and intercropping, which influence the spider community. Thus, this study was intended to determine the spider abundance and diversity of the tea plantation, and the intercropping field (tea and strawberry) at Serang village, Karangreja Sub-District, District of Purbalingga. A survey and purposive sampling techniques were conducted, then the spiders were hand collected. Shannon-Wiener diversity (H’), Evenness (E), Simpson’s dominance (D), and Sorensen’s similarity (IS) indices were used to measure the spider diversity. The results revealed a total number of 575 individual spiders from 10 families, i.e., Araneae, Araneidae, Clubionidae, Linyphiidae, Lycosidae, Nephilidae, Oxyopidae, Salticidae, Tetragnathidae, Theridiidae, and Thomisidae. Araneidae was the most abundant in both fields. The total abundance of spiders in tea plantation (379 individuals), however, was greater than that in the intercropping field (196 individuals). Shannon-Wiener diversity reached H’= 1.873 in the plantation, and H’= 1.975 in the intercropping field.

Abstract

The productivity of strawberry (Fragaria sp.) depends on the presence of pollinator insects that need nectar or pollen as their food. The diversity and the population size of pollinator insects can be increased by the companion planting of Borreria laevicaulis among the strawberry. This research aimed to determine the diversity of pollinator insects of strawberry plantation companion by B. laevicaulis and to determine the relationship between the diversity of pollinator insects with the strawberry fruit produced. This research was conducted in the strawberry plantation of Serang Village, of the District Karangreja, Purbalingga, from June to August 2012. The research was designed to determine the effect of companion planting of B. laevicaulis at the 0%, 5%, 10%, and 15% of the total individuals of strawberry. The results showed that the companion planting of B. laevicaulis in the strawberry field did not affect the species diversity of pollinator insects. But the B. laevicaulis companion planting affected the amount of strawberry yielded. The maximum yield was obtained by planting B. laevicaulis at the 10% of the strawberry individuals; it was increased by 76.12% of the control without companion planting.
