“…This further affirmed the beneficial impact on food crop production other than better morphological growth due to intercrop earlier pointed out as an advantage in intercropping (Herera and Harwood 1973;Okigbo and Greenland, 1975;Okigbo, 1977). Putra et al (2012) who probed the effect of intercropping style on growth of one-year-old oil palms reported that the food crops grown as intercrop with the juvenile oil palms did not inhibit the growth rate and performance of the juvenile oil palms which were the main crop. This is in concurrence with the findings of this study in which the intercropped juvenile oils were found to produce a better performance than the non-intercropped juvenile oil palms by recording higher canopy and trunk heights, canopy spread, and number and length of fronds.…”

Many farmers spend a lot of money in the control of weeds during the long juvenile phase of oil palm. Intercropping is a popular practice employed by farmers to increase productivity of wide alley and overcome weed problem. However, improper intercropping of Elaeis guineensis with other crops has impaired the growth and development of the oil palm due to competition for environmental resources. The study was conducted to investigate the impact of intercropping on the growth of juvenile oil palm for 2 years. The research commenced during the rainy season of 2016 at an established juvenile oil palm plantation in Ala, Akure-North Local Government of Ondo State. Four fruit vegetables were intercropped separately within the alley of the plantation at 1, 2 or 3 m away from the oil palms in a randomized complete block design. Growth parameters of intercropped and non-intercropped juvenile oils were compared. Results of the study revealed that at 16 weeks after intercropping (WAI), the intercropped oil palm recorded better growth performance with higher values of canopy spread, number of frond, number of leaflets and trunk height (218.20, 37.00, 87.48 and 38.17 cm) respectively, than the sole oil palms (214.67, 32.83, 72.89 and 31.67) respectively. There was no significant difference in all the growth parameter examined except canopy height at (P<0.05) level of significance. Juvenile oil palm cultivated in rainforest agroecological zone of Nigeria can be intercropped with fruit vegetables without any deleterious effect when intercropped at minimum of 1 m away from the oil palms.

“…Jenis tumbuhan yang lebih beragam akan menyediakan lebih beragam serangga serta musuh alami. Semakin banyak vegetasi bawah yang terdapat di dalam suatu habitat, maka semakin banyak pula sumber nutrisi dan inang alternatif yang dapat digunakan oleh musuh alami untuk dapat melangsungkan kehidupannya (Putra et al, 2012). Batang dan tual sagu yang tidak dimanfaatkan, menarik serangga herbivor, predator, dan detritivor yang memungkinkan tersediannya telur, larva, pupa, dan imago sebagai inang parasitoid.…”

Sago (Metroxylon sagu Rottb) in Maluku grow naturally to form sago forest ecosystem. Hymenoptera in the sago forest ecosystem has not been studied. This study aims to examine the diversity of Hymenopterous parasitoids in sago forests in Maluku. The research was conducted in Ariate, Eti, Waisamu, Rutong, Tawiri, and Tulehu in September 2015 - October 2016. Hymenopterous parasitoids were collected through swing nets, light traps, yellow pan traps, and pitfall traps. Results the abundance of hymenopterous parasitoids in six sago areas in Maluku was found to be 14 families and 32 species. The morphoses of morphospecies are 68 morphospecies of Sago Ariate forest 32 morphospecies, Eti 37 morphospecies, Waisamu 9 morphospecies, Rutong 11 morphospecies, Tawiri 19 morphospecies, and Tulehu 37 morphospecies. The high diversity index (2.18 - 3.55) per location, Morphospesies wealth of Tulehu is higher than other location, while the individual abundance of Ariate is higher than other villages. The average relative abundance of Scelionidae, Scoliidae and Ichneumonidae families was higher by 26.46%, 15.95%, and 10.89%, respectively. There are three families with high morphospecies and individual abundance in each sago area ie Scoliidae in sago forest area of Ariate and Waesamu, Scelionidae on Rutang, Eti, and Tawiri sago wood area, while Eulophidae on sago Tulehu area. There are 12 unique species or species with only certain locations and none in other locations, each Ariate (2 species), Eti (2 species), and Tulehu (8 species).ABSTRAK Sagu (Metroxylon spp.) merupakan tanaman sosial, budaya dan ekonomi di Maluku dengan potensi hutan sagu cukup tersedia. Teridentifikasi gejala kerusakan empulur pati dan tajuk tanaman sagu akibat serangga. Kebijakan pengendalian hayati melalui pelepasan parasitoid dalam sistem aplikasi Pengendalian Hama Terpadu merupakan salah satu alternatif. Hymenoptera parasitoid pada ekosistem hutan sagu penting untuk dipelajari morfospesiesnya sebagai data dan informasi ilmiah dalam menunjang program pengembangan agens hayati dalam pengelolaan serangga herbivor tanaman sagu. Penelitian ini bertujuan untuk mengkaji keanekaragaman Hymenoptera parasitoid pada hutan sagu di Maluku. Dalam penelitian ini dipilih tiga lokasi di Pulau Ambon dan tiga lokasi di Pulau Seram, kemudian masing-masing lokasi dipilih tiga rumpun sagu contoh secara acak. Setiap rumpun sagu dalam lingkaran radius 5m dari pohon sagu utama seluas 100m2 dilakukan pengambilan serangga melalui jaring serangga, perangkap lubang, dan perangkap nampan kuning, sedangkan perangkap lampu dilakukan pada satu titik disetiap lokasi. Pengambilan serangga dilakukan pada musim kemarau dan hujan dibulan September 2015 – Oktober 2016. Hasil penelitian menunjukkan bahwa kelimpahan Hymenoptera parasitoid pada enam lokasi hutan sagu diperoleh sebanyak 14 famili dan 30 morfospesies. Kekayaan morfospesies disetiap lokasi berkisar antara 5-21 morfospesies, dengan proporsi koleksi serangga melalui penggunaan jaring serangga lebih tinggi. Indeks keanekaragaman tinggi (2.18 – 3.55) per lokasi, kelimpahan individu di Ariate dan kekayaan morfospesies di Tulehu masing-masing lebih tinggi dari lokasi lainnya. Rata-rata kelimpahan relatif famili Scelionidae, Scoliidae, dan Ichneumonidae masing-masing 26.46%, 15.95%, dan 10.89%. Terdapat 12 spesies unik masing-masing Ariate (dua spesies), Eti (dua spesies), dan Tulehu (delapan spesies). Scelionidae, Scoliidae, Ichneumonidae dan Eulophidae merupakan kelompok parasitoid telur-larva potensial yang terindikasi berasosiasi dengan serangga herbivor pada tanaman sagu dari ordo Coleoptera dan Orthoptera.
