Two species of mealybug, Ferrisia virgata and Planococcus minor were previously reported as vectors of Piper yellow mottle virus (PYMoV), the causal agent of mottle disease in black pepper (Piper nigrum). Several activities were performed to study the PYMoV transmission through F. virgata and Pl. minor, involving transmission experiment in ISMCRI greenhouse (Bogor, West Java), field observation of mealybugs, and mottle disease incidence at ISMCRI field station (Sukabumi, West Java). The result showed that the transmission rate of PYMoV through F. virgata and Pl. minor in black pepper reached 40.00 and 46.67%, respectively. Field temperature >33 °C, light intensity >700.00 lux, wind speed <1.10 m/s, and rainfall <80 mm/month were recorded during the occurrence of a peak population of mealybugs. Mealybugs population in the field was affected by insecticide application. Its population was lower in a block with insecticide spraying than in a block without insecticide spraying. Furthermore, mottle disease incidence was correlated with the population level of mealybugs. Based on PCR detection, the frequency of viruliferous mealybugs did not differ in a block with or without insecticide spraying, i.e., 6/39 and 6/37, respectively. This indicated that other factors than insect vectors might play an important role in disease spread.

“…Virus spread most likely happened early in the season when vector population was present in the field and the virus continuously replicated in the plants so more and more plants were expressing symptoms as the season progressed. Chandra et al (2016) and Alif et al (2018) reported that plants infected with low concentration of virus do not express the typical symptoms of the disease until later in the season. Therefore, the results confirmed that the vector could act as inoculum source for infection in the field.…”

Pepper yellow leaf curl Indonesia virus (PepYLCIV), a Begomovirus in Geminiviridae, is transmitted in a persistent manner by Beminisa tabaci Genn. (Hemiptera: Aleyrodidae). The virus has caused tremendous damages to chili plants in Indonesia. The disease had been reported non seed-transmissible and exclusively transmitted by whitefly, however, our field observations and previous reports showed that high disease incidence was present in the absence of vector. Therefore, the present study was conducted to determine the roles and the importance of seed, vector in the seedbed, and vector in the field as a source of primary inoculum for disease development. To determine whether the disease is seed-transmissible, seeds from PepYLCIV-infected plants were sown in cage and sprayed with insecticide weekly to prevent B. tabaci infestation. Vector population and PepYLCIV incidence were monitored weekly. To determine whether the vector acted as inoculum source in the seedbed, certified seeds of chili cv. Pilar were sown in caged and uncaged seedbeds. To determine whether vector acted as inoculum source in the field, caged seedlings were planted in open field (uncaged). Our results indicated that PepYLCIV is seed transmissible with an incidence of 2.5%. The highest disease infection was found on uncaged plants both in the seedbed and in the field. Therefore, the use of healthy seeds and protecting seedbed from vector infestation is very important in preventing infection on the seedlings. Besides that, any control measures in a frame of integrated pest management should be employed to suppress the vector population in the field.

Produksi tanaman lada tidak sejalan dengan upaya ekstensifikasi dan intensifikasi pemerintah, hal ini disebabkan masih banyaknya infeksi penyakit pada tanaman lada bahkan cenderung bertambah baik dari jenis penyakit maupun intensitas infeksi penyakitnya. Informasi mengenai perkembangan penyakit tanaman lada di area centra produksi lada yang jarang diperbaharui. Penelitian ini dilakukan untuk mengamati dan menentukan kejadian dan keparahan penyakit tanaman lada menggunakan metode purposive samping. Hasil penelitian ditemukan 3 jenis penyakit yang menginfeksi tanaman lada di Kabupaten Bangka Selatan, yaitu penyakit kuning, busuk pangkal batang dan kerdil virus. Tingkat kejadian dan keparahan penyakit relatif lebih tinggi terjadi di Kecamatan Tukak Sadai. Kejadian penyakit kuning lada, penyakit busuk pangkal batang, dan penyakit virus berkisar 3,33-90,48 %; 43,70 %; dan 12,5-100 %, secara berturut-turut. Keparahan penyakit busuk pangkal batang mencapai 43,11 % dan penyakit virus berkisar 4,58-59,57 %.
