“…BnYDV was found as a new tentative species in south-eastern Spanish bean greenhouses (Segundo et al 2004a). Up to now, BCMV and BCMNV have been considered the predominant viruses in bean crops in Spain (Saiz et al 1995).…”

“…Symptoms induced by BnYDV are easily mistaken for other physiological alterations caused by aging or environmental changes, thus making symptomological detection more difficult. Finally, symptoms caused by SBMV consisted of smooth mosaic on the leaves followed by deformations of variable intensity, plus pod deformation (Verhoeven et al 2003;Segundo et al 2004b; Fig. 3i).…”

“…Primers used in this work are described in Table 4. RT-PCR amplifications of cucumovirus, potyviruses, carlaviruses, luteovirures, SBMV and BnYDV, as well as PCR amplifications of TYLCV and geminiviruses, were conducted as previously described (Robertson et al 1991;Badge et al 1996;Wyatt and Brown 1996;Gibbs and Mackenzie 1997;Choi et al 1999;Accotto et al 2000;Verhoeven et al 2003;Segundo et al 2004a). Primers for detecting TSWV and PVuV were designed based on sequences retrieved from GenBank.…”

“…This disease is also caused by Tomato yellow leaf curl Malaga virus (TYLCMalV), a new species that appeared by natural recombination of TYLCV with the bean non-infecting begomovirus Tomato yellow leaf curl Sardinia virus (TYLCSV; Sanchez-Campos et al 1999;Monci et al 2002Monci et al , 2005. Other beaninfecting viruses were identified during the course of our research, such as Southern bean mosaic virus (SBMV, Verhoeven et al 2003) and the new proposed species Bean yellow disorder virus (BnYDV, Segundo et al 2004a). The following study was conducted in south-eastern Spain from 2000-2005, in order to determine the presence and incidence of viruses in bean crops.…”

A study was conducted to determine the identity and prevalence of viruses in 455 greenhouses in the main Spanish green bean growing area. Directed surveys were conducted in 422 crops from 2000-2004 to collect samples from diseased plants displaying symptoms that could be attributed to viruses. The samples were analysed to detect any virus by means of dsRNA extraction, mechanical inoculation to test plants, as well as ELISA and/or RT-PCR tests to detect potyviruses, geminiviruses and viruses previously known to infect beans in Spain. Random surveys were conducted in the years 2002 and 2005 (in 21 and 12 greenhouses, respectively) to study the actual incidence of known viruses in the area. Symptoms were recorded in 23,108 plants from which 664 plants were collected and analysed by ELISA or RT-PCR. The results of the directed surveys showed that all the analyzed crops carried the cryptic virus Phaseolus vulgaris endornavirus (PVuV), whereas phytopathogenic viruses appeared in smaller percentages of the crops: Tomato yellow leaf curl virus (TYLCV) 20.4%, Southern bean mosaic virus (SBMV) 9.0%, Tomato spotted wilt virus (TSWV) 4.0%, and the new species Bean yellow disorder virus (BnYDV) that broke out in 2004 with occurrence values higher than 34.3% that year. From 2000-2004 an important decrease in TYLCV was observed, along with a slight increase in SBMV and a consistently low occurrence of TSWV. The results of the random surveys confirmed the increased occurrence of virus detected during the directed surveys, and furthermore demonstrated the percentage of incidence for each virus.

“…In regions where there is a great density of vegetable crops cultivated in greenhouses, as is found in the southeast of Spain, the whitefly becomes a serious threat in terms of the increase of its population and the potential transmission of several viral diseases (Navas-Castillo et al 2000;Segundo et al 2004;Ruiz et al 2006). Crops such as sweet peppers, tomatoes, melons, cucumbers, green beans and others may be seriously affected by this pest.…”

9Bemisia tabaci is a significant pest for many crops, but there are few population studies of this 10 insect on sweet pepper (Capsicum annuum). In this study, stage frequency data were generated with 11 B. tabaci in sweet pepper plants in various situations, and the Bellows and Birley method was used 12 to obtain population parameters from the data. The Akaike Information Criterion (AIC) was used to 13 select the best option of the Bellows and Birley method and, in some cases, to estimate the 14 parameters of the population using model averaging. The ratios estimated/observed for each 15 population parameter were calculated to assess bias and were used to correct the estimations if the 16 ratios were different from 1. The effects of different factors on the estimations of population 17 parameters were analysed. The total duration of development was affected by the experimental 18 conditions (laboratory vs. greenhouse) and temperature, but it had the highest precision. The final 19 survival rate was affected by temperature, and the estimation of individuals entering each stage was 20 affected only by the options included in the Bellows and Birley method. AIC helped to detect 21 differences in the daily survival rate among the different experiments between N1 (first instar) 22 (range 0.842-0.923), and the egg (range 0.989-1.0) and N4 (fourth instar) (0.990). The methodology 23 used can be employed in field population studies. For example, the final survival rate in the 24 2 greenhouse experiments varied between 0.624 and 0.097, depending on if the parasitoids were 25 present or not, and the total development varied between 420.6 and 440.7 degree-days. 26 27
