El objetivo de la investigación fue identificar hospedantes alternos de Iris yellow spot virus (IYSV) y establecer el rango de hospedantes del putativo vector(es) en regiones productoras de cebolla (Allium cepa) de Morelos y Michoacán, México. En 10 localidades de ambos estados se muestrearon cultivos de cebolla y arvenses, en presencia y ausencia del cultivo. Las plantas de cebolla se analizaron por RT-PCR y las arvenses por DAS-ELISA. Las arvenses se identificaron a nivel especie, los trips colectados de las mismas se establecieron colonias para su identificación por PCR, con iniciadores específicos que amplifican un segmento del gen de citocromo oxidasa I (COI). Se analizaron e identificaron 295 arvenses agrupadas en 56 especies (23 familias), todas resultaron negativas para IYSV. Se detectaron trips en 75 arvenses agrupadas en 17 especies. Se analizaron 33 poblaciones de trips (22 de Morelos y 11 de Michoacán). La secuenciación indicó identidad con Thrips tabaci con una homología superior a 97 %. Las arvenses Ricinus communis y Acalypha ostryifolia registraron el mayor número de T. tabaci. En cebolla se confirmó la presencia de IYSV con RT-PCR en las 10 parcelas muestreadas. Este es el primer reporte de la presencia de IYSV en el estado de Michoacán.

“…Beberapa spesies gulma, seperti Monochoria vaginalis, Cyperus rotundus, C. iria, Echinochloa colonum, E. crus-galli, Eleusine indica, Fimbristylis miliacea, Imperata cylindrica, dan Limnocharis flava sering dimanfaatkan sebagai tempat bertelur beberapa jenis musuh alami (Karindah et al 2011), bahkan Leersia hexandra menjadi tempat berkembang yang baik bagi musuh alami yang ditunjukkan dengan tingginya populasi dan keragaman jenisnya (Masfiyah et al 2014). Selain berperan sebagai inang alternatif bagi hama dan juga gulma bagi berbagai jenis patogen penyebab penyakit pada tanaman utama (Smith et al 2012).…”

“…While this spatial delineation is implicitly recognized and many studies have tested the impacts of the two scales independently, few have integrated within-field and landscape-level factors into a single analysis (but see Kennedy et al, 2013;Scheper et al, 2015;Tamburini et al, 2016). For example, while there is evidence that insect-vectored crop viruses are mediated by both within-field weeds (e.g., Duffus, 1971;Ali et al, 2012;Smith et al, 2012;Srinivasan et al, 2013) and surrounding land cover (e.g., Fabre et al, 2005;Margosian et al, 2009;Carrière et al, 2014), there have not been direct comparisons of the relative strength of these two scales. Uncovering differences between spatial scales is important for crop protection because it reveals which management approaches may be more or less effective in combating pests.…”

Landscape composition is more important than local management for crop virus–insect vector interactions

Managing crop viruses is difficult due to complex interactions among vectors, reservoirs, and mediating factors such as land cover. Identifying the appropriate ecological neighborhood, or the spatial area in which the most influential interactions occur affecting virus epidemiology, would therefore be beneficial in exposing which of the many explanatory variables to target in the plant-pathogen system. We constructed partial least squares path models to find the neighborhood size for vectors of stylet-borne nonpersistent viruses infecting pumpkins, and compare the relative influence of within-field and extra-field land cover. Two economically important aphid-vectored viruses in the U.S. Midwest are included in these analyses: papaya ringspot virus (PRSV) and watermelon mosaic virus (WMV). In 2010 and 2011, we used commercial pumpkin fields to quantify virus infection, vector (aphid) alightment (i.e., landing rates), and within-field weed communities, and subsequently analyzed extra-field cover from 1-5 km concentric buffer zones within the surrounding landscape. Alightment rates of total noncolonizing vectors and the top three numerically dominant species (Aphis craccivora Koch, Therioaphis trifolii (Monell), and Rhopalosiphum padi [L.]) were included in individual path models. Overall, we found that extra-field landscape composition had a far stronger influence on vector alightment than within-field weed cover; this pattern was consistent for seven of eight statistical models. In one exception, weed cover influenced alightment of the putative PRSV vector, A. craccivora, while surrounding landscape had no effect. In this case, weed coverage and vector alightment were inversely related, demonstrating that aphids were less likely to land in weed-infested fields. However, weed cover did not predict alightment of T. trifolii or total noncolonizers. The neighborhood size scales for total noncolonizers' tended to be larger than for individual species (4-5 km), suggesting future studies of dispersal by multi-species aphid groups may benefit from an extended gradient. On balance, our results indicate that while surrounding land cover interactions are complex, they exert greater influence over vector dispersal than within-field weed cover, calling into question whether management of local weeds is an effective method of crop virus prevention in some systems.
