“…This hypothesis is confirmed by the lower amount of sugars and sugar alcohols in an apple tree cultivar X65-11 (E31-10) which is resistant to C. pomonella egg-laying than in the susceptible cultivar Golden Delicious (Lombarkia & Derridj unpubl.). (Derridj et al, 1992). Particular ratios of metabolites on the plant surface may also give specific information on plant organ and its stage of development (Stammitti et al, 1995).…”

Water soluble metabolites identified from surfaces of apple tree fruit and leaf stimulate oviposition in Cydia pomonella L. The effects of two artificial blends of primary metabolites representing fruit and leaf surfaces, respectively, and of components within the blends were examined on egg-laying after two time periods: 3 min and 25 min of darkness. An artificial mixture of six metabolites, viz., three sugar alcohols (sorbitol, quebrachitol, and myo-inositol) and three sugars (glucose, fructose, and sucrose) did stimulate egg-laying. Fructose, sorbitol, and myo-inositol are important components of the stimulatory blend. Contact durations may induce variations in egg-laying responses. After 3 min of darkness, there were no differences in numbers of females laying eggs nor in the numbers of eggs laid on cloths treated with the complete blends and the controls. There were, however, clear effects of groups of compounds and of individual compounds. Reduced blends without sugars and sugar alcohols were in many cases significantly less stimulatory than the complete blends and the controls. After 25 min of darkness, the proportions of females laying eggs as well as the numbers of eggs were higher after treatment with the complete blends than on the controls. The proportions of females laying eggs on cloths treated with the reduced blends were rather similar to the controls, whereas there were still significant effects on the numbers of eggs laid after treatment with reduced blends derived from fruits but not from leaves.

“…Surface metabo- lites have already been shown to be egg-laying stimulants in other insects: myo-inositol in a citrus-feeding species, Papilio protenor (Honda, 1990), dulcitol (stereo-isomer of sorbitol) in Y. cagnagellus feeding on Euonymus europaeus (Roessingh et al, 2000), and fructose in Ostrinia nubilalis Hbn. (Derridj et al, 1992).…”

“…Little attention has so far been paid to stimuli present on the plant surface that are known to influence egg-laying in other insects (Städler, 1986;Derridj et al, 1989Derridj et al, , 1992Derridj et al, , 1996Fiala et al, 1990;Derridj, 1996;Soldaat et al, 1996). The sugar alcohol sor-bitol is a primary metabolite which is characteristic of ligneous Rosaceae.…”

“…Ekstrak pentana pada jagung fase tasselling dapat menstimulasi oviposisi; sementara telur, kotoran larva, dan tanaman atau bagian tertentu tanaman yang rusak memancarkan volatil yang dapat mengusir betinagravid untuk oviposisi pada lahan atau tanaman yang sudah ada kelompok telur atau larva (Bas et al 2008). Ketertarikan betina untuk meletakkan telur pada daun juga disebabkan oleh lebih tingginya kadar glukosa di permukaan daun daripada batang (Derridj et al 1992). Kebanyakan kelompok telur diletakkan pada daun-daun tengah (± 54% dari 632 kelompok telur), seperti pada hasil penelitian ini (Gambar 4).…”

ABSTRAKPenggerek jagung Asia, Ostrinia furnacalis Guenée, dikenal sebagai hama penting tanaman jagung baik pada fase vegetatif maupun fase generatif. Pada fase generatif, pengambilan keputusan pengelolaan O. furnacalis perlu didasarkan pada kepadatan kelompok telur sebelum telur hama menetas dan tanaman mengalami kerusakan. Studi penyebaran kelompok telur O. furnacalis dilakukan pada tanaman jagung di Kebun Pendidikan, Penelitian, dan Pengembangan Pertanian (KP4) UGM, Yogyakarta. Tujuan penelitian adalah mengetahui sebaran horizontal dan vertikal kelompok telur O. furnacalis pada tanaman jagung fase generatif dan pola sebarannya, baik horizontal maupun vertikal. Pengamatan dilakukan terhadap jumlah kelompok telur pada setiap tanaman sampel, berdasarkan sebaran vertikal/horizontal. Pola sebaran dianalisis menggunakan rasio ragam terhadap rata-rata (σ2/μ = I δ ), indeks Morisita (I γ ), dan parameter binomial negatif (nilai-κ). Hasil pengamatan menunjukkan bahwa pola sebaran kelompok telur O. furnacalis baik horizontal maupun vertikal adalah mengelompok (σ2 > μ atau σ2/μ > 1). Sejalan dengan bertambahnya umur tanaman, derajat pengelompokkan tersebut cenderung menurun (nilai-κ meningkat; nilai indeks Morisita menurun) dan ada kemungkinan bergerak menuju acak (sebaran Poison) bergantung pada heterogenitas lingkungan, seperti iklim mikro, ketersediaan makanan berupa tanaman atau bagian tanaman yang disukai, dan musuh alami. Hasil penelitian ini menyimpulkan bahwa pola sebaran horizontal maupun vertikal kelompok telur O. furnacalis pada tanaman jagung fase generatif adalah mengelompok dengan derajat pengelompokkan yang cenderung menurun dengan bertambahnya umur tanaman jagung. Informasi tentang penyebaran kelompok telur O. furnacalis dapat digunakan untuk menjelaskan biologi dan ekologi serangga dan pengembangan strategi manajemen hama yang efektif. Kata kunci: Ostrinia furnacalis, sebaran kelompok telur, indeks dispersi ABSTRACTAsian corn borer, Ostrinia furnacalis Guenée, is known as an important pest of maize, Zea mays L., in both whorl and reproductive stages. Management decisions based on egg-mass density is useful because decision is made before damage occurs. Observation on O. furnacalis egg-mass distribution in maize-field was carried out in Agricultural Training, Research, and Development Station (ATRD) UGM, Yogyakarta. The number of egg-masses laid on each plant surface in maize-field was sampled
