4-(4-methoxyphenyl)-3-buten-2-on has been synthesized from p-anisaldehyde and acetone via aldol condensation. The reaction was performed at room temperature under basic condition for 12 hours to give brown solid of product (m.p 64-65 oC) in 66.19 % yield. p-anisaldehyde itself was produced from oxidation of anetol major component of anise oil by the use of potassium permanganate as a oxidator. The structure of the products was analyzed by FTIR, 1H NMR and GC-MS. Activity test of 4-(4-methoxyphenyl)-3-buten-2-on as an attractant was carried out in Sleman with methyl eugenol as a reference. The result showed that 4-(4-methoxyphenyl)-3-buten-2-on was inactive compound as a fruit flies attractant and some of fruit flies, i.e. Bactrocera papayae, B. carambolae, B. umbrosa and B. abdolonginqua was found on the test area.

4-(3,4-dimethoxyphenyl)-3-buten-2-on has been synthesized from veratraldehyde and acetone via aldol condensation. The reaction was performed at room temperature under basic condition for 24 hours to give brown solid of product (m.p 64-6 5oC) in 73.7% yield. Veratraldehyde itself was produced from alkylation of vanillin by the use of dimethylsulfate. The structure of the products was analyzed by FTIR, 1H NMR and GC-MS. Activity test of 4-(3,4-dimethoxyphenyl)-3-buten-2-on as an attractant was carried out in Sleman, Bantul and Kulon Progo with methyl eugenol as a reference. The result showed that 4-(3,4-dimethoxyphenyl)-3-buten-2-on was inactive compound as a fruit flies attractant and some of fruit flies, i.e. Bactrocera papayae, B. carambolae, B. umbrosa and B. abdolonginqua was found on the test area.

Spodoptera frugiperda (Lepidoptera: Noctuidae) has successfully invaded and spread to almost all provinces of Indonesia which may cause significant impacts on corn production. Local natural enemies could play an important role in managing this invasive insect, and more diverse ecosystems would benefit natural enemies. This study aimed to assess parasitization rates of S. frugiperda eggs by local egg parasitoids in three different corn ecosystems (agroforestry, rice field, and rainfed field) in East Java. Sentinel egg masses were used for this study by exposing eight-hour-old egg masses collected from the laboratory mass-rearing and left for 24 hours in corn plantations aged 7, 14, and 28 days after planting. Telenomus sp. was more abundant in the three ecosystems compared to Trichogramma sp. The egg mass parasitization varied from 15.6 to 52.5%. The number of egg masses parasitized was consistently higher in agroforestry, followed by rice fields and rainfed fields in all three different sampling times. Interestingly parasitization rates on egg masses were not different, and they ranged from 43.7 to 81.6%. These findings provide evidence on the importance of local egg parasitoids for managing S. frugiperda and some insights related to plant diversity to improving the services by these parasitoids.

The melon fly, Bactrocera cucurbitae is serious pest attacks fruits and vegetables. The manipulation of male mating behavior that displays acoustic signals is one of the steps in the behavior-based control strategy of B. cucurbitae. The first study period determines the courtship song characteristics, frequency, and occurrence time. The recording was carried out when B. cucurbitae was mated using recording devices at 04.00–07.00 pm. The results show three sounds produced before copulation, namely, calling, courtship, and stimulating, with frequencies 274.30 ± 3.29 Hz, 284.65 ± 2.00 Hz, and 304.36 ± 1.82 Hz. B. cucurbitae courtship song began at 04.00–06.26 pm. The second study was performed to determine the effect of experimental acoustic playback stimulus on the selection of mating pairs by females. The acoustic playback stimulus is made synthetically by playback of two channels, namely, calling and courtship sounds, with frequencies of 274 and 284 Hz at a sound pressure level (SPL) of 85 dB. The experimental results of acoustic playback stimulus show that the sexual behavior of female B. cucurbitae was disrupted and marked by the decreased number of copulations during SPL is high, resulting in the overlapping calling and courtship sounds frequencies that impair signal detection.
