Background: Whitefly is one of the most destructive sucking pest in the tropical and subtropical regions of the world and causing significant crop losses directly by sucking sap from the plants and indirectly through the transmission of viral diseases specifically caused by the genus Begomovirus. The Begomovirus species viz., Mungbean yellow mosaic India virus (MYMIV) and Mungbean yellow mosaic virus (MYMV) are causing yellow mosaic virus disease in soybean, which is transmitted by whiteflies. The disease accounts to 30-70 per cent yield loss and increases up to 80 - 100 per cent during severe incidence. Hence, there is a need for development of integrated pest management strategies against disease and whiteflies, for this the knowledge on virus-vector relationship is required. But, the studies on biological relationship of yellow mosaic virus disease and whitefly in soybean are scarce. At this juncture, considering the importance of disease in soybean, the present investigation was carried out to know the virus -vector relationship of the YMV and whitefly in soybean.Methods: The experiment on virus-vector relationship of yellow mosaic virus and whitefly in soybean was conducted at Department of Entomology, College of Agriculture, G. B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand during 2016-17. The data on number of whiteflies per plant, acquisition and inoculation access feeding period and pre and post starvation period required for effective transmission of virus was recorded.Result: A single viruliferous whitefly was able to transmit virus and ten viruliferous whiteflies per plant were required for cent per cent transmission of virus. The minimum acquisition access and inoculation access feeding periods required for virus transmission was 0.25h (15 min) each; while the 100 per cent virus transmission was recorded with acquisition and inoculation period of 12h, each. The per cent transmission was increased with the increase of acquisition and inoculation periods. The rate of transmission was positively correlated with pre-acquisition starvation period and negatively correlated with post- acquisition starvation period.

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.

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.

First Time

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.
