Abstract: Aster yellows is a sporadic disease of vegetable crops (lettuce, carrot and celery) in the North Central US. The pathogen, a phytoplasma, is transmitted by the aster leafhopper (Macrosteles quadrilineatus Forbes). A simulation model has been developed to study the effects of spatial patterns of fields of host and non-host crops and spatiotemporal pattern of cultural and chemical controls for the disease and insect vector, respectively, on disease epidemics. The model is spatially explicit, simulating leafhopper reproduction, development and movement among individual fields. Simulations demonstrated that both the pattern of long range dispersal and the arrangement of host and nonhost fields can affect aster yellows epidemics and yield loss. If the source of inoculum is within the production area, insecticidal control of vectors in early plantings can protect later plantings, although protection may be more easily achieved by placing later plantings at a suitable distance from earlier plantings. Sensitivity analysis of model parameters also indicates that an increased crop incubation period, the time between infection and symptom expression, could greatly reduce losses from this disease in lettuce.

Abstract: This study revealed that feral aster leafhoppers, Macrosteles quadrilineatus Forbes, exposed to aster yellows phytoplasma live longer and may lay more eggs than nonexposed leafhoppers. Aster leafhoppers were reared on asters infected with either of 2 strains of aster yellows phytoplasma or uninfected asters. After eclosion, adults were placed on uninfected healthy lettuce or oat plants and transferred periodically. The life span of test leafhoppers and the number of offspring they produced were compared. Females reared on noninfected aster plants lived for an average of 19 d, those reared on ësevereí and ëboltí strain aster yellows phytoplasma-infected plants lived 26 and 28 d, respectively. The mean number of offspring produced by females reared on the bolt strain of aster yellows phytoplasma-infected asters was almost twice the number produced by nonexposed leafhoppers. The life span of feral leafhoppers or the number of eggs laid did not differ for leafhoppers maintained on either oats or lettuce after exposure to aster yellows phytoplasma-infected asters. Female leafhoppers lived twice as long as males. Our results suggest that the aster leafhopper may have had a long association with aster yellows phytoplasma. The longer life and higher fecundity of phytoplasma-infected leafhoppers may influence disease dynamics of aster yellows in lettuce.

Abstract: Factors that affect aster leafhopper flight were examined in laboratory and field experiments. In both the laboratory and the field, differences between males and females in flight between plants within or just above the canopy were documented. Host plant and phytoplasma infection had no effect on the within-canopy flight behaviors, which were consistent with reproductive biology for the Cicadellidae. Plant species and size did affect the number of vertical flights out of the canopy. Male aster leafhoppers infected with the phytoplasma moved more frequently than uninfected males between plants, although plant residence times for uninfected and infected males were similar.

Abstract: Mean latent period and transmission rate of 2 strains (bolt and severe) of aster yellows phytoplasma in nymph and adult aster leafhoppers, Macrosteles quadrilineatus Forbes, were studied under controlled conditions at 15, 20, 25, and 30 degree C. There was a nonlinear relationship between mean latent period and temperature with shorter mean latent periods at higher temperatures ( apprxeq 20-25 d) than at lower temperatures ( apprxeq 40-80 d) for both aster yellows phytoplasma strains and both ages of leafhoppers. The proportion of leafhoppers that became vectors was significantly higher for bolt strain when leafhoppers acquired aster yellows phytoplasma as nymphs than as adults. However, there was no difference in the proportion that became vectors of the severe strain by the 2 age groups. Once leafhoppers became inoculative, the rate of transmission remained constant over their life spans when monitored by serial transfers at 48-h intervals. Increases in temperature and access time of leafhoppers increased the proportion of leafhoppers that became vectors after feeding on bolt strain-infected plants. Also, the effect of aster yellows phytoplasma exposure on life spans of leafhoppers was studied at 4 temperatures. At 25 and 30 degree C, leafhoppers exposed to both aster yellows phytoplasma strains lived longer than those leafhoppers not exposed. Data can be used in an aster yellows epidemiological model to evaluate strategies for aster yellows management.

Abstract: Leafhopper populations were sampled with sweep nets in grain cover and vegetable crops during 1988 and 1989. Populations in vegetable crops consisted primarily of aster leafhopper, Macrosteles quadrilineatus Forbes, except for potato crops in which Empoasca spp. were ocmmon. Adult aster leafhoppers were caught several weeks before nymphs in each year. Peak catches of aster leafhopper adults and nymphs occurred in both June and July. Data were consistent with the hypothesis that aster leafhoppers migrate to Ohio vegetable-growing areas in late May and June. Air trajectory analysis indicated three possible source areas of M. quadrilineatus migrating into Ohio vegetable-production areas: Arkansas, Louisiana, Texas, and Oklahoma; western Ohio, Indiana, and Illinois; and a corridor extending from Ohio to the Dakotas. Bioassays for aster yellows during 1989 and 1990 indicated that the leafhopper populations present during those years contained very few inoculative individuals. Growers should base treatment decisions on monitoring for inoculative aster leafhoppers.
