The North

The varieties (64) of common beans (Phaseolus vulgaris L.) were evaluated for resistance to bean rust in the Velasco zone, at the north of the Holguín province, Cuba. The evaluation was made 60 days after sowing by determining the degree of attack using a scale as well as estimating the number of pu stules per leaf and no remarkable differences between both methods were found. The character of the pustules was also determined by measuring their diameters with regard to three categories large (more than 0.5 mm) middling (between 0.3 and 0.5 mm) and small (less than 0.3 mm) and the presence or lack of chlorotic halo surrounding the pustules as well. The cultivars that resulted less attacked by the bean rust were Guira-35, XAN-43, Revolución-79, M-112, Rosas, BAT-202, Tazumal, Huetar, Bolita-42, BAT-1281, BAT-1274, BAT-1280, PV-555, BAT 1275, Engañador, Guamá- 23, MCD-254, Chevere, XAN-93, XAN-147, NAG-20, NAG-55, RAB-30 and CC 25-9-S (R), all of which showed an average equal or inferior to 10 pustules per leaf, being these ones generally smaller and without any chlorosis.

Important Disease

Bean rust caused by Uromyces appendiculatus (Pers.) Unger is an important disease in common bean (Phaseolus vulgaris L.) worldwide. To our knowledge this is the first report of a new race of U. appendiculatus (19-63) in Puerto Rico and in the western hemisphere. Accepted for publication 4 February 2009. Published 25 March 2009.

Specific Virulence

Five isolates of the bean rust fungus Uromyces appendiculatus were shown to be specifically virulent on bean genotypes of Andean origin. This specificity was demonstrated by the virulence of five pairs of isolates on a differential set of 30 Phaseolus vulgaris landraces. Each isolate pair was from a different country in the Americas and consisted of one Andean-specific isolate and one nonspecific isolate. Of the differential P. vulgaris landraces, 15 were of Middle American origin and 15 were of Andean origin. The Andean-specific rust isolates were highly virulent on Andean landraces but not on landraces of Middle American origin. Rust isolates with virulence to Middle American landraces were also generally virulent on Andean material; no truly Middle American-specific isolates were found. Random amplified polymorphic DNA (RAPD) analysis of the rust isolates also distinguished the two groups. Four of the Andean-specific rust isolates formed a distinct group compared to four of the nonspecific isolates. Two of the isolates, one from each of the two virulence groups, had intermediate RAPD banding patterns, suggesting that plasmagomy but not karyogamy occurred between isolates of the two groups.

The beetle Astylus variegatus (Germ.) (Coleoptera: Melyridae) is frequently found in flowers feeding on pollen. Responses of A. variegatus to volatile floral attractants were studied in common beans (Phaseolus vulgaris L.) fields. Traps originally designed to capture Diabrotica speciosa (Germ.) (Coleoptera: Chrysomelidae), consisted of plastic bottles (2 L) with 150 holes (5-mm diameter) yellow gold painted and containing inside a plastic strip (3.5 <FONT FACE=Symbol>´</FONT> 25 cm) with Lagenaria vulgaris (L.) powder (0.28% B cucurbitacin - feeding stimulant and arrestant for diabroticites) sprayed with carbaril insecticide. Treatments consisted of 1,4-dimethoxybenzene (one or two dispensers per trap), 1,4-dimethoxybenze + indole, 1,4-dimethoxybenzene + cinnameldehyde and control. Volatile average release rates (over ten days) was approximately 32 mg day-1 per dispenser under laboratory conditions. 1,4-dimethoxybenzene-lured traps caught significantly more beetles than the control, three and seven days after trap setting. Ten days after the onset of the experiment, there were no differences in number of beetles caught by treatments. Captures were higher in the 1,4-dimethoxybenzene + cinnamaldehyde treatment than in 1,4-dimethoxybenzene only in the first assessment. Adding indole to 1,4-dimethoxybenzene did not improve beetle captures.
