Effect of Monitoring Trap and Mating Disruption Dispenser Application Heights on Captures of Male Grapholita molesta (Busck; Lepidoptera: Tortricidae) in Pheromone and Virgin Female-Baited Traps
ABSTRACT Studies were conducted in 0.07-to 0.18-ha peach and apple plots to determine the effects of pheromone trap and hand-applied emulsiÞed wax pheromone dispenser application heights on captures of Grapholita molesta in traps baited with pheromone lures or virgin females. Traps and pheromone dispensers were placed either low (1.2Ð1.8 m) or high (2.7Ð 4 m) within tree canopies. In the majority of cases, equivalent numbers of male G. molesta were caught in traps placed at the low and high positions in both pheromone-treated and untreated plots. Furthermore, pheromone dispensers placed at the low and high positions equally disrupted orientation of male G. molesta to pheromone traps placed at either height and to virgin female traps placed at 1.2Ð1.8 m within canopies season-long at most sites. Our results indicate that for trees Յ3.5 m tall, dispensers with release rates Ն18 mg/ha/h placed at 1.5Ð2.0 m (heights easily reached from the ground) should effectively disrupt mating of G. molesta throughout tree canopies. In trees between 3.5 and 4.5 m tall, the dispensers should be moved to Ϸ1.5 m from the top of the canopy. For trees taller than 4.5 m, we recommend hanging dispensers both in the top and bottom thirds of tree canopies. Most commercial Michigan peach and apple trees are Ͻ3.5 m tall. Eliminating the need to apply dispensers high in the canopy in most orchards will enable growers to reduce application costs, thereby facilitating increased adoption of mating disruption for G. molesta control by growers
Anxiety and Depression Prevalence Rates in Age-Related Macular Degeneration
PURPOSE. To estimate the prevalence rates of depression and anxiety in patients with wet age-related macular degeneration (AMD) and the relationship with visual acuity and to develop a simple algorithm for depression screening. METHODS. This cross-sectional, prospective, observational, multicenter study was performed in France, Germany, and Italy. Retina specialists at 10 centers per country each enrolled 12 consecutive patients with wet ARMD. Patients were stratified into four severity groups by using best eye (BE) and worst eye (WE) visual acuity (VA) thresholds (BE:VA 20/40 and WE:VA 20/200). Patients rated themselves on the Hospital Anxiety and Depression Scale (HADS). Analysis of variance was performed to estimate the effect of VA severity levels on HADS scores adjusted on age, gender, and country. RESULTS. Patients (females 609/6) were recruited, with a mean age of 77 years and 2.3 years' disease duration. Mean BE:VA at inclusion was 0.49 logMar (logarithm of the minimum angled of resolution) and NW:VA 1.0 logMar. The prevalence of severe depression increased from 0% (BE:VA >= 20/40+WE:VA >= 20/200) to 7.6% (BE:VA < 20/40+)WE:VA < 20/200), whereas anxiety was unrelated to VA loss. Moreover, total depression scores were strongly associated with VA severity (P = 0.006), but not total anxiety scores (P = 0.840). Responses to two HADS items ("I still enjoy things I used to enjoy"; "I can enjoy a good book or radio or television program") identified 95% of severely to moderately depressed patients. CONCLUSIONS. Self-rated depression in patients with AMD was associated with VA severity level. It should, therefore, be relatively easy for ophthalmologists to implement the screening procedure and refer identified patients to psychiatrists for proper assessment and treatment
