Abstract

In management of thrips on strawberry, farmers usually use synthetic insecticides. Synthetic insecticide is not effective to control thrips and produce residual effect on crops. Insecticidal residue is dangerous for human, natural enemies and environment widely. Therefore, it is necessary to find an alternative thrips pest control on strawberries, through integrated pest manage-ment (IPM) implementation. Research was aimed to determine the effect of IPM technology for Thrips sp. on strawberry plantation. Research was conducted on strawberry plantation by comparing IPM and conventional plots, in Kusuma Agrowisata Batu from April to July 2009. Variables were used such as the number of larvae, adult population and damage intensity caused by Thrips sp., and fruit production. Data was analyzed by t-test on 5%. The results showed that the average larva and adult population of Thrips sp. on IPM plot were higher than conventional plot, 1.12 and 0.50 for larva and 0.87 and 0.27 for adults respectively. The damage intensity of strawberry crops on IPM plot was higher than conventional plot, 11.69 and 5.98% respectively. Based on average fruit production, IPM plot was higher than conventional plot, 48.32 g and 39.24 g respectively.

Abstract

As an important pest, Helopeltis Antonii reduces cocoa yields ca. 32-44 %. Related to H. antonii, this research aimed to identify the arthropods diversity, population and attack intensity of H. antonii in three different managements of cocoa plantations i.e. Kedaton, Banjarsari and Nogosari, Jember district, East Java, Indonesia from February 2014 to February 2015. The arthropod collection was done by visually, sweep net, yellow pan, malaise and pitfall traps. Arthropods diversity and similarity were analyzed by Margalef species richness index (R), Shannon-Wiener diversity index (H?), Evenness index (E), Simpson dominance index (C) and Sorensen Similarity index (SS). The different number of arthropod, population and attack intensity of H. antonii between plantations were examined by Wilcoxon test. The research showed that the highest species richness, diversity and evenness index values was in Nogosari and it was in a stable condition. About 10 orders, 35 families and 41 species of arthropods in Nogosari, it was higher than two other cocoa plantations. Nogosari was different from Kedaton and Banjarsari based on Sorensen Similarity Index with 78.26 and 77.78 % respectively. In addition, population dynamic and attack intensity of H. antonii in the three cocoa plantations were different in a year.

Abstract

The Research was aimed to identifythe diversity of arthropods in Cocoa plantation inthree strataof shade tree. Research was conducted in Rahmat village, the sub-district of Palolo, District of Sigi, the Province of Central Sulawesi, Indonesia from December 2012 to June 2013.Berlese funnel, Pitfall, Malaise and Light trap were used to collect arthropod samples. There were five indices such as species richness (R), species evenness (E), species diversity (H`and D), and species similarity (Iss) to analyze the diversity of arthropods in cocoa plantations. The result showed that species richness (R) of arthropods under the two strata of shade tree, species evenness (E) and both of species diversity indices, Shannon (H`) & Simpson (D) was the highest, with value of 18,216, 0.839, 4.383, and 0.833 respectively. In addition, percentage of species similarity (Iss) was the highest under two strata of shade tree with value 72.297%.Keywords: arthropods, cocoa, species diversity, two strata of shadetree
