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

This research aimed to find out an abundance of Thrips sp. population on Integrated Pest Management (IPM) and  conventional farming at chilli plantation. The research was conducted on August until November 2012 at the Bayem Village, Sub-distric Kasembon, Malang, East Java and Entomology Laboratory, Departement of Plant Protection, Agriculture Faculty, Brawijaya University. The methods to determine abundance population Thrips sp. was using quadrant  with 4 plants samples in 1 beds were taken. The observation was using 16 plants, on the each treatment of IPM and conventional farming. The result showed that the population of Thrips sp. (nymph) on IPM and conventional was not significantly different, while the population of Thrips sp. (adult) in the IPM treatment was significantly higher compared to conventional. Plant height on IPM treatment was higher than conventional treatment. The statistical analysis on Thrips sp. attacks indicated, that the intensity of damage on IPM treatment (0.16 %) and conventional treatment (0,14 %) were not significantly different. The yield of chilli on the IPM (31%) was significantly higher than compared to conventional treatment. Chilli cultivation costs on IPM was higher (2.5%) rather than the conventional. The yield of chilli plant per hectare on IPM had advantage higher (37%) than conventional. The calculation of the BCR at the IPM was higher (27%) than the conventional farming.Key words: Abundance, analysis of farming, IPM, Thrips sp.

Abstract

Scales have attacked 9 hectares of apple land spread in 8 villages of Bumiaji sub-district such as Giripurno village, Tulungrejo village, Pandanrejo village, Sumbergondo village, Bulukerto village, Punten village, Gunungsari village, and Bumiaji village. This pest is a perennial pest on apple crops and difficult to control. The current way of control has not been able to overcome this pest problem. Therefore, research is needed to get effective control technology and easy to implement. The use of colour traps in addition to control needs, and also expected to needs of monitoring and identification of existing problems that make this pest difficult to control. This research was conducted to find out the effect of colour trap to community structure at Junggo, Tulungrejo Village, Bumiaji Sub-district, Batu City. Colour traps are fitted with 10 types of treatment colour with 3 replication. The observational data were analyzed by using community test. The results showed that the community analysis on the colour trap indicating that the index of diversity (H') and the dominance index (C) all treatments and families were small but the uniformity index (E) belonged to the stable community was owned by treatment B8 white colour with height 1.5m) and B9 (clear colour with height 1m). The largest dominant index (C) data of Diaspididae family (scales) is owned by B7 treatment (white colour with height 1m) of 0.18. The natural enemy species of scales found on apple plants is Encarsia strenua (silvestri) : Famili Aphelinidae.Key Words: Apple, Colour trap, Scales
