Abstract

Penelitian dilaksanakan pada areal pertanian lahan kering bercampur semak dalam Hutan Lindung Sirimau dengan tiga metode pengambilan sampel yakni hand collecting, bait trap (umpan gula dan  ikan tuna) dan pitfall trap dari bulan Juli hingga september 2011. Penelitian bertujuan mengetahui penyebaran semut pada areal pertanian lahan kering  dalam kawasan Hutan Lindung Sirimau Ambon. Hasil penelitian menemukan 1 family, 4 genus dan  19 jenis semut dengan total individu mencapai  14.456. Jenis – jenis semut yang sangat dominan dalam kawasan yakni Anoplolepis gracilipes, Pheidole sp 1, Odontoponera denticulata, Pheidole megacephala, Technomyrmex albipes, Tetramorium simillimum, Tetramorium bicarinatum, Tapinoma melanocephalum, dan Paratrechina longicornis. Kelimpahan jenis semut mencapai 0,934 tergolong sedang dengan penyebaran jumlah individu semut dan tingkat kestabilan komunitas sedang. Penyebaran semut dipengaruhi oleh intensitas cahaya matahari, suhu, kelembaban, angin, air dan musim. Perbedaan suhu mikro, iklim, cahaya, kelembaban, pola makan, kompetisi interspesifik, variasi ketersediaan sumber makanan, kualitas habitat dan aktivitas manusia juga ikut mempengaruhi penyebaran semut dalam kawasan.

Abstract

The control of the Spodoptera exigua Hubner (Lepidoptera: noctuidae) through sex pheromones is feasible by mass trapping, mating disruption, and population monitoring. Both synthetic sex pheromones and virgin females were used on the mass trapping and population monitoring methods as attractant source. The virgin females must be available through the mass rearing without affected on its pheromone content production. Therefore, a study on the response of the female’s pheromone which reared by artificial and natural diets was important to be done. The GCMS analysis result had shown that female’s pheromone glands extract which had reareded by natural diets contained tetradecan-1-ol (0.23%) pheromone compounds and several other compounds, such as hexadecane (14.31%), heptadecane (0.42%), nonadecane (1.09%), and beta-caryophyllene (1.37%). Meanwhile, only tridecanol (3.39%), hexadecane (8.52%), nonadecane (0,23%), and trans-caryophyllene (3.11%) compounds had been found on the artificial ones. The cross-copulation test showed that both types of moths could do mating. The field trapping test showed that both extracts were attractive to males

Abstract

This study aims to determine the diversity of ants in cocoa (Theobroma cacao L.) ecosystems in six hamlets in the village of Banjaroya, District Kalibawang Yogyakarta. The sampling was carried out by the method of feeding ants using tuna and sugar solution, which is placed on the cacao tree and the ground surface; pit-fall traps; and direct picking by hand. Six sub-family of ants, namely Cerapachynae, Dolichoderinae, Myrmicinae, Ponerinae, and Pseudomyrmicinae were found. Six of the most abundant genera found in each catchment were Dolichoderus sp., Anoplolepis sp., Paratrechina sp., Crematogaster sp., Pheidole sp., and Pheidologeton sp., which is known to be aggressive and invasive. The analysis showed that the diversity of ant communities in the Village Banjaroya categorized as medium (H ‘> 1-3), meaning that the overall state of the ecosystem of the cocoa crop was classified as stable or steady. Meanwhile, the results of the analysis of the dominance index (C) shows that the community of ants in each village tends was tended to be dominated by a single species (C close to 0). The relationship between habitat condition and the diversity of ant was discussed in this article.  Penelitian bertujuan untuk mengetahui keragaman semut pada ekosistem kakao (Theobroma cacao L.) di 6 dusun di Desa Banjaroya, Kecamatan Kalibawang Yogyakarta.

Abstract

Some empirical studies have revealed the ecological consequence of interspecific relationships among predatory arthropods that is the disruption of natural functions of indigenous species of predators on their preys, i.e. phytophagous arthropods. In relation to many efforts on the utilization of introduced species of natural enemies, particularly predatory arthropods, the effects oflntraguild Predation (IGP) on key predators should be considered carefully to optimize their potency. In addition, understanding the impact of biological traits of each species of predatory arthropods on their ability to adapt from being predated by other species might be important to predict their composition and possibilities for being exist in ecosystem.

Abstract

Cocoa pod borer (CPB), Conopomorpha cramerella Snellen (Lepidoptera: Gracillariidae) is a major pest of cocoa. Detection of the pest infestation using sex pheromone traps in the early growth and development of cocoa pods is important for an early warning system programme. In order to prevent the pest infestation the young pods were wrapped with plastic bags. A research to study the CPB incidence was conducted at cocoa plantations in Banjarharjo and Banjaroya villages, District of Kalibawang; Hargotirto and Hargowilis villages, District of Kokap; and Pagerharjo village, District of Samigaluh, Yogyakarta. The experiments design used RCBD with four treatments (sex pheromone trap, combination of sex pheromone trap and pod wrapping, pod wrapping, and control) and five replications. As many as 6 units/ha pheromone traps were installed with a distance of 40 m in between. Results showed that one month prior to the trap installation in the experimental plots there were ripen cocoa pods as many as 9-13%, which were mostly infested by CPB. During the time period of introducting research on August to Desember 2016 there was not rambutan fruits as the CPB host, hence the CPB resource was from infested cocoa pods. The CPB moth trapped as many as 0−7 (1.13 ± 0.14) moths/6 traps/12 observations. The seed damage due to CPB larvae in the pheromone trap treatments (23.98%) was relatively similar with the control (20.25%). Seed damage rate in combination treatment of pheromone trap and pod wrapping (0.59%) was relatively the same with the pod wrapping (0.20%). The pheromone trap was more usefull for monitoring tool rather than for control, meanwhile pod wrapping was an effective control measure of CPB. IntisariPenggerek Buah Kakao (PBK), Conopomorpha cramerella Snellen (Lepidoptera: Gracillariidae) merupakan salah satu hama utama kakao. Deteksi serangan hama PBK dengan perangkap feromon seks pada awal pertumbuhan dan perkembangan buah kakao penting dilakukan sebagai sistem peringatan dini. Dalam upaya pencegahan serangan hama tersebut dilakukan pembrongsongan buah muda. Penelitian dilakukan di kebun kakao rakyat di Desa Banjarharjo dan Banjaroya, Kecamatan Kalibawang, Desa Hargotirto dan Hargowilis, Kecamatan Kokap, serta kebun PT Pagilaran di Desa Pagerharjo, Kecamatan Samigaluh, Yogyakarta. Percobaan dengan empat perlakuan (perangkap feromon, kombinasi perangkap feromon dan brongsong, brongsong, kontrol) dan lima ulangan menggunakan rancangan RCBD. Perangkap feromon sebanyak 6 unit/ha dipasang dengan jarak antar perangkap sekitar 40 m. Hasil percobaan menunjukkan bahwa satu bulan sebelum pemasangan perangkap terdapat buah tua sebanyak 9−13 % dan umumnya terserang PBK. Selama kajian berlangsung tidak terdapat buah rambutan sebagai inang PBK sehingga sumber PBK diduga hanya dari buah kakao yang terserang. Ngengat PBK yang tertangkap yaitu sebanyak 0−7 (1,13±0,14) ekor/6 perangkap/12 pengamatan. Intensitas kerusakan biji akibat ulat PBK pada perlakuan perangkap feromon (23,98%) relatif sama dengan kontrol (20,25%). Kerusakan biji kakao pada perlakuan kombinasi perangkap feromon dan pembrongsongan (0,59%) relatif sama dengan pembrongsongan saja (0,20%). Perangkap feromon lebih berfungsi sebagai alat monitoring daripada alat pengendalian PBK, sedangkan pembrongsongan buah merupakan teknologi pengendalian PBK yang efektif.

Abstract

Corn borer is one of the important pests on corn plant in Gorontalo Province, especially in three districts which are the center of maize planting development. Corn borer and its natural enemy complex in Gorontalo Province has not been clearly studied. The purpose of this study is to determine the complexity of the natural enemies of maize stem borer by calculating the diversity and composition. The survey method was used, in which the older larvae, pupae, and corn borer natural enemies were collected from the field in the three districts (Gorontalo, Boalemo, and Pohuwato). Observation plots in each district area of 2,500 m2, were divided into 3 sub plots with the size of 3×3 m, each plot is consisted of 45 plants at the spacing of 75×25 cm. The data were analysed descriptively and organized into tables. Shannon Index was used to count the diversity and composition of the pests and their natural enemies. The results showed that the corn borer species was Ostrinia furnacalis, while the dominant natural enemy was the tachinid fly. The analysis of Shannon diversity index for natural enemies of three districts of Gorontalo, Boalemo, and Pohuwato were 0.63, 0.61, and 0.97 respectively. Penggerek batang jagung adalah salah satu hama penting pada tanaman jagung di Provinsi Gorontalo terutama di tiga kabupaten sentra pengembangan jagung.

Abstract

Oviposition preference of a predatory hoverfly, Episyrphus balteatus on the presence of its potential predators, the ladybird larvae which are inflicted serious impacts on its eggs was examined in a non-choice test. Our results revealed that the biggest and the most aggressive species of ladybird, Harmonia axyridis caused the worst impact on hoverfly eggs by attacking and feeding on. The species and developmental stages of ladybird were attributed to the level of predation risk. We correlated the oviposition site selection by hoverfly females to the egg predation risk level inflicted by ladybird larvae. Hoverfly females laid the least number of eggs on the patches attended by the strongest competitor, the larva of H. axyridis, and tended to lay the highest number of eggs on colonies attended by the weakest competitor, the larva of Scymnus posticalis. In addition, the impact of the fourth instar larva of ladybirds was stronger than of the first instar larva.
