This study was conducted to determine the effect of maize as barrier crop to prevent the spread of Bemisia tabaci (Gennadius), the yellow virus vector in pepper farming. The research was conducted in the field at Pakem, Sleman, during two cropping seasons from October 2014 to February 2015 as first planting period and in April to August 2015 as second planting period. The escalation of B. tabaci (Gennadius) populations was directly correlated with virus yellow peppers increment. The result indicated that planting barrier was effective in reducing the spread of B. tabaci (Gennadius) in pepper plants. The population of B. tabaci (Gennadius) in plots with pepper surrounded by maize was lower compared to plots without maize barrier, showed that the yellow virus spreads on pepper can be minimized, and hence the incidence of yellow disease was also decreased.Penelitian ini dilakukan untuk mengetahui pengaruh penanaman jagung sebagai pemberian tanaman pembatas (barrier) untuk mengatasi penyebaran Bemisia tabaci (Gennadius) yang merupakan vektor virus kuning pada tanaman cabai. Penelitian dilakukan di lahan pertanaman cabai di Pakem, Sleman. Penelitian dilaksanakan selama dua musim tanam dari bulan Oktober 2014 sampai dengan bulan Februari 2015 pada periode tanam I dan bulan April 2015 sampai dengan bulan Agustus 2015 pada periode tanam II. Meningkatnya populasi B. tabaci (Gennadius) berbanding lurus dengan meningkatnya virus kuning pada cabai. Hasil penelitian ini menunjukkan bahwa penanaman tanaman pembatas (barrier) cukup efektif mengurangi penyebaran B. tabaci (Gennadius) pada ke dalam petak tanaman cabai. Populasi B. tabaci (Gennadius) pada petak tanaman cabai yang dikelilingi tanaman jagung lebih rendah jika dibanding dengan petak tanaman cabai yang tidak dikelililing tanaman jagung, sehingga secara tidak langsung penyebaran virus kuning pada cabai dapat diminimalisir.

Indicator Plant and PCR-RAPD for Biotype Determination of Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae).B. tabaci has been known world wide as a major pest and virus vector of horticulture. In Indonesia the presence of B.tabaci was reported since 1980 and its role as virus vector in tomato and chilli pepper has becoming more importantrecently. Genetic diversity of B. tabaci has been well recognized, but very little information available for diversity of B.tabaci in Indonesia. This research was conducted in Bogor, West Java from May 2004 to June 2005. The aim of thisresearch was to initiate basic information regarding genetic diversity of B. tabaci in Indonesia, particularly in Java Island.Whiteflies population collected from different crops, i.e. tomato, broccoli, chill pepper, eggplant, cucumber, soybean, andedamame, was evaluated using silverleaf-induction test, and RAPD-PCR. It was evidenced that only B. tabaci populationfrom broccoli was able to induce silverleaf. Two genetic types of B. tabaci, i.e. biotype B and non B, were identified basedon polymorphism character of DNA. Population from broccoli was belong to biotype B, whereas other populations fromtomato, chill pepper, eggplant, cucumber, soybean, and edamame were belong to biotype non B.

Pola tanam sayuran secara tumpang sari telah dimanfaatkan secara meluas di sentra-sentra produksi  sayuran di Indonesia. Penelitian ini bertujuan mengetahui pengaruh pemupukan dan tumpangsari antara tomat dan kubis terhadap populasi Bemisia tabaci dan serangan penyakit virus kuning yang disebabkan oleh virus gemini pada tanaman tomat. Penelitian dilaksanakan di Kebun Percobaan Balai Penelitian Tanaman Sayuran, Lembang (1.250 dpl.) dari bulan Juni sampai dengan Oktober 2008. Rancangan yang digunakan ialah acak kelompok pola faktorial dengan empat ulangan. Dua faktor perlakuan yang diuji, yaitu (1) dosis pupuk (N 180 kg/ha + P2O5 150 kg/ha + K2O 100 kg/ha,  N 168 kg/ha + P2O5 146,5 kg/ha + K2O  145 kg /ha, serta  N 210 kg/ha + P2O5 183,125 kg/ha + K2O 181,25 kg/ha) dan (2) cara tanam (monokultur tomat dan tumpangsari tomat dengan kubis). Hasil penelitian menunjukkan bahwa penggunaan dosis pupuk yang tinggi dan tanaman tomat yang ditanam secara monokultur dapat meningkatkan populasi kutukebul dan serangan penyakit virus kuning dibandingkan dengan dosis pupuk yang lebih rendah. Penggunaan dosis pupuk yang tinggi tidak berpengaruh nyata terhadap peningkatan produksi tomat. Penggunaan dosis pupuk N 168 kg/ha + P2O5  146,5 kg/ha + K2O 145 kg/ha dan tumpangsari tomat dengan kubis dapat direkomendasikan sebagai komponen teknologi PHT untuk pengelolaan hama B. tabaci dan penyakit virus kuning pada tanaman tomat.<br /><br />The intercropping planting technique is widely implemented in vegetable production centers in Indonesia. The research on the application of different doses of fertilizers (N, P, and K) and the planting technique of tomato and cabbage  on B. tabaci and the yellow disease caused by gemini virus was carried out at the Indonesian  Vegetables Research Institute from June to October 2008. The objective was to determine the effect of different doses of fertilizers (N, P, and K) and tomato-cabbage intercropping on the population densities of B. tabaci and incidence of gemini virus on tomato.  A factorial randomized block design with two factors and four replication was used in the experiment. Two treatments factor were tested i.e.  (1) different doses of fertilizers (N 180 kg/ha + P2O5 150 kg/ha + K2O 100 kg/ha,  N 168 kg/ha + P2O5 146,5 kg/ha +  K2O 145 kg/ha, and  N 210 kg /ha +  P2O5 183,125 kg/ha + K2O 181,25 kg/ha), and (2) planting techniques (monoculture and tomato-cabbage intercropping). The result indicated that heigher doses of fertilizers resulted in higher population of whitefly per leaf and yellow virus symptoms on tomato compared to lower doses. Higher amounts of fertilizers did not significantly affect tomato yield. It is suggested that the dose of  N 168 kg/ha + P2O5 146,5 kg/ha + K2O 145 kg/ha, and the tomato-cabbage intercropping technique can be incorporated into the IPM program, especially for the management of  whitefly and gemini virus on tomato.<br /><br /><br />

Seven species of whitefly (Hemiptera: Aleyrodidae) are recorded for the first time from Gibraltar, six of which are non-native introductions. The most notable species are: Bemisia tabaci (Gennadius) complex, which is a major economic agricultural and horticultural pest, and virus vector; and Singhiella simplex (Singh), which is native to S.E. Asia, feeding exclusively on Ficus spp., and a recent introduction to the Mediterranean. Singhiella simplex is also recorded for the first time from Mallorca (Spain) and Morocco.

ABSTRACTMany animal and plant viruses depend on arthropods for their transmission. Virus-vector interactions are highly specific, and only one vector or one of a group of vectors from the same family is able to transmit a given virus. Poleroviruses (Luteoviridae) are phloem-restricted RNA plant viruses that are exclusively transmitted by aphids. Multiple aphid-transmitted polerovirus species commonly infect pepper, causing vein yellowing, leaf rolling, and fruit discoloration. Despite low aphid populations, a recent outbreak with such severe symptoms in many bell pepper farms in Israel led to reinvestigation of the disease and its insect vector. Here we report that this outbreak was caused by a new whitefly (Bemisia tabaci)-transmitted polerovirus, which we named Pepper whitefly-borne vein yellows virus (PeWBVYV). PeWBVYV is highly (>95%) homologous toPepper vein yellows virus(PeVYV) from Israel and Greece on its 5′ end half, while it is homologous toAfrican eggplant yellows virus(AeYV) on its 3′ half. Koch's postulates were proven by constructing a PeWBVYV infectious clone causing the pepper disease, which was in turn transmitted to test pepper plants byB. tabacibut not by aphids. PeWBVYV represents the first report of a whitefly-transmitted polerovirus.IMPORTANCEThe high specificity of virus-vector interactions limits the possibility of a given virus changing vectors. Our report describes a new virus from a family of viruses strictly transmitted by aphids which is now transmitted by whiteflies (Bemisia tabaci) and not by aphids. This report presents the first description of polerovirus transmission by whiteflies. Whiteflies are highly resistant to insecticides and disperse over long distances, carrying virus inoculum. Thus, the report of such unusual polerovirus transmission by a supervector has extensive implications for the epidemiology of the virus disease, with ramifications concerning the international trade of agricultural commodities.
