Pengelolaan habitat dengan menerapkan teknologi budidaya kakao yang baik harus dilakukan untuk memperbaiki kesuburan tanah, meningkatkan keanekaragaman hayati dan meningkatkan kesehatan tanaman. Tujuan penelitian adalah mengetahui pengaruh pengelolaan habitat terhadap serangan penggerek buah kakao (PBK) Conophomorpha cramerella dan kepik pengisap buah Helopeltis antonii. Penelitian dilaksanakan bulan Oktober 2013 sampai April 2014 di kebun kakao rakyat di Kecamatan Sumbermanjing Wetan, Kabupaten Malang, Jawa Timur. Desain penetapan sampel tanaman kakao ditentukan berdasarkan metode kuadran sistematik dua dimensi. Perlakuan terdiri dari petak pengelolaan habitat berupa aplikasi rorak, irigasi tetes dengan teh kompos, penambahan bahan organik, dan biopori cacing, dan petak konvensional yang dikelola berdasarkan kebiasaan petani. Masing-masing blok terdiri dari 24 sub blok pengamatan dan jumlah tanaman per sub blok adalah 4 pohon. Pengamatan meliputi jumlah buah, bobot biji basah, kelimpahan serangga, persentase dan intensitas serangan C. cramerella dan H. antonii. Hasil penelitian menunjukkan pengelolaan habitat secara signifikan meningkatkan jumlah buah kakao, meningkatkan keanekaragaman serangga terutama serangga yang menjadi musuh alami, serta menurunkan persentase dan intensitas serangan C. cramerella dan H. antonii.Kata kunci: Pengelolaan habitat, kakao, Conophomorpha cramerella, Helopeltis antoniiHabitat management of cocoa cultivation must be carried out to improve the fertility of soil, increase the biodiversity and the plantâs health. The objective of this study was to elucidate the effect of habitat management on the cocoa pod borer Conophomorpha cramerella and cocoa mirid Helopeltis antonii attack. The research was conducted from October 2013 to April 2014 in Sumbermanjing Wetan District, Malang Regency, East Java. The research was compared cocoa plantation with habitat management and the conventionally managed cocoa plantation as a control. Habitat manipulation techniques used in this research were providing ditch and worm biopores, applying organic matter and compost tea drip irrigation.

Flowering weeds can serve as refugia for natural enemies. In coffee plantation, they might has the potential to attract predator and parasitoid of Coffee Berry Borer (CBB), Hypothenemus hampei Ferr. (Coleoptera: Scolytidae). The aim of this research was to elucidate the influence of weeds to the presence of predator dan parasitoid and their impact to the population of CBB. The research was conducted at Ngantang, Malang Regency and in Laboratory of Pest, Faculty of Agriculture, Brawijaya University. Three types of weed used were: Ageratum conyzoides L. (Asteraceae), Synedrela nodiflora(L.) Gaertn. (Asteraceae), and Arachis pintoi Krap. & Greg. (Fabaceae). The research consisted of two experiments (1) coffee plot with single species of weed and (2) coffee plot with two species of weeds. The results of experiment I and II showed that A. conyzoides, S. nodiflora, A. pintoi and its combination in coffee plantation significantly attracted the predator and parasitoid of CBB. The population of CBB was not significantly different between coffee plot with and without weed. The existence of A. conyzoides, S. nodiflora and A. pintoi in coffee plantations could increase the number of predator and parasitoid of CBB around coffee tree. This result showed that the presence of weeds in coffee plantation is an important factor in maintaining the predators and parasitoid of CBB population.

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

EFFECT OF NATURAL HABITAT ON DIVERSITY OF HEMIPTERAN PREDATOR IN OIL PALM PLANTATION Rizali, Akhmad; Himawan, Toto; Fitriani, Ima; Rahardjo, Bambang Tri; Karindah, Sri; Puspitarini, Retno Dyah; Sahari, Bandung

Effect of Natural Habitat on Diversity of Hemipteran Predator in Oil Palm Plantation. Utillization of natural enemies in controlling oil palm pests still encounters obstacles, in particular, how natural enemies can survive and establish in oil palm plantations. The existence of natural habitats around oil palm plantations can allegedly support the occurence of natural enemies. The objective of this study was to investigate the effect of the presence of natural habitats on diversity of hemipteran predators in oil palm plantations. Field research was conducted in oil palm plantations located in Pangkalan Bun, Central Kalimantan. The plots were oil palm plantations with different distances from natural habitat i.e. near (less than 200 m), medium (about 2 km) and far (about 5 km). Each plot was selected six trees for fogging using insecticide with active ingredient lamda cyhalothrin. Based on research result, diversity of hemipteran predator in oil palm plantion was found 19 species belong to 2 families. The most dominant hemipteran predator was Sycanus sp., Eocanthecona sp. and Reduviidae sp5. The distance of oil palm plantation from natural habitat did not affect species richness, abundance and composition as well as recolonization of hemipteran predator in oil palm plantation. Abundance of hemipteran predator tend to decrease in different observation time, except Sycanus sp. Sycanus sp was likely has ability to rapidly recolonized and their occurrence were influenced by flowering vegetation in oil palm plantation.

Lecanicillium lecanii is an insect pathogenic fungus that is often used for pest control and has a wide range of hosts. The L. lecanii is capable of infecting several types of host insects including the Order Orthoptera, Hemiptera, Lepidoptera, Thysanoptera and Coleoptera. The extent of this fungus host range was feared to have a negative effect on predator insects Menochilus sexmaculatus. This study aims were to determined the pathogenicity of the fungus L. lecanii against the imago predatory beetle M. sexmaculatus, to know how the predation ability and the number of eggs fecundity of Imago M. sexmaculatus after application L. lecanii. The research was arranged in Randomized Block Design with 4 replications. The conidia density of L. lecanii used were 106, 107, 108, 109 conidia/ml, 1 ml / l of lufenuron insecticide as positive control and sterile distilled water as negative control. The research showed that the mortality percentage of M. sexmaculatus due to L. lecanii application is low and medium. The L. lecanii was not affected for preying ability on imago M. sexmaculatus but gave effect to the number of eggs fecundity of imago M. sexmaculatus.

This research aims to assess the environmental factors that affect the abundance of scales populations on the apple crop. The study was conducted in July 2012 to January 2013. The study was conducted at two sites with different altitude. Bumiaji village's altitude is Â±900 m and Tulungrejo village's altitude is Â±1,515 m asl. Multiple linear regression analysis was conducted to determine the environmental factors that affect the abundance of scales populations on the apple crop. Based on the results of the regression analysis, air temperature and humidity affect the abundance of scales populations in Binangun while rainfall and long solar radiation have no effect. Scales population abundance of the apple crop in Binangun was influenced by air temperature and humidity one week before. Based on the results of the regression analysis, air temperature, air humidity and rainfall affect the abun dance of scales population in Tulungrejo while long solar radiation has no effect. Scales population abundance ofthe apple crop in Tulungrejo was affected by air temperature two weeks before, while humidity and rainfall were affected one week before. The higher air temperature scales, flea population level will increase. And the higherrelative humidity, scales population levels will increase.
