“…To monitor the presence of the adult stage of D. antiqua in the field, we used water pan traps (Finch & Collier, 1989), blue in colour, which do not reflect the UV part of light (Ishikawa et a/., 1985;Vernon & Bartel, 1985; Judd er a/., 1988). Traps were checked twice weekly to collect and identify flies.…”

Delia antiqua is a serious pest of many species of the genus Allium, including onions and chives. Over a period of two years (1997/1999), we have developed a model to simulate the population dynamics of D. antiqua based on an extended Leslie model. The model structure as well as the developmental functions for the different life stages of D. antiqua are presented. Using daily mean air and soil temperatures, the model calculates the population matrix for developmental stages of D. antiqua including eggs, larvae, pupae and adults. The simulation can be used to optimize the timing of control measurements against a specific life stage of D. antiqua. Flight activity can be simulated using wind speed as additional information. Simulated flight activity and the observed flight activity of D. antiqua monitored with water pan traps in three different regions of Germany in 1998 are presented and discussed. The model, which was programmed as part of the SWAT 3.5 package of programs to simulate the population dynamics of root-fly pests in horticultural crops, will also be available via other expert systems such as PASO.

“…Painted rectangles were coated with Stikem Special | (Seabright Enterprises, Emeryville, California), folded along the narrow axis and clipped at a 90 ~ angle to the top of a 1 • 3 cm cedar stake (Vernon & Bartel, 1985). TiO2-white paint was mixed in varying proportions with black, blue (E871), green (E785) and yellow (E776) semi-gloss enamel paints | (Cloverdale Paint and Chemicals' product codes in brackets) to produce, one, eight-step achromatic (to the human eye) grey series, and three, six-step chromatic series of different hues.…”

“…Visual behaviour of the onion fly, Delia antiqua (Meigen) has been examined in the laboratory (Vernon, 1979;Harris & Miller, 1983) and in the field (Vernon & Borden, 1983;Ishikawa et al, 1985;Vernon & Bartel, 1985;Vernon, 1986). Laboratoryreared flies alight most frequently on yellow-green surfaces, both in the laboratory and in the field.…”

Visual behaviour of the onion fly, Delia antiqua: antagonistic interaction of ultraviolet and visible wavelength reflectance

The interaction of ultraviolet (UV = 350-400 nm) and visible (VISIBLE = 400-650 nm) wavelengths in the visual behaviour of the onion fly, Delia antiqua (Meigen), was examined by measuring spontaneous alightment on various UV-and non-UV-reflecting, sticky cardboard traps in onion fields. Alightment on traps was negatively correlated with the percent UV (350 nm) and green (540-580 nm) reflectance and positively correlated with the percent blue (430-470 nm) reflectance. Alightment varied directly with the ratio of 'stimulatory'/'inhibitory' reflected wavelengths. Males and females were similar in their response to both UV and VISI-BLE wavelength reflectance, with the exception that males were more sensitive than females to UV-reflecting white surfaces. A multiple regression model, that used the intensity of 3 key wavelengths, 350, 450 and 560 nm, as independent variables, explained 90% of the variation in the combined male and female response to spectral reflectance from traps. These results indicate that some visual behaviours of D. antiqua are a function of the integration of sensory input from the entire spectral distribution of the stimulus, and not simply the dominant wavelengths or hue.

“…However, visual characteristics are rarely specific of a particular host plant (Prokopy & Roitberg, 1984). Properties such as hue (dominant wavelength of reflected light), saturation (spectral purity of reflected light), and brightness (intensity of reflected light) may play a role in insect orientation, as showed by Vernon & Bartel (1985) in Delia antiqua (Meigen). On the other hand, Aluja & Prokopy (1992, 1993) showed that when fruits are not visible or scarce, fruit odor may interact with visual cues throughout the searching process.…”

Visual response of the tomato fruit fly, Neoceratitis cyanescens, to colored fruit models

To determine how mature females of the tomato fruit fly, Neoceratitis cyanescens (Bezzi) (Diptera: Tephritidae), detect host fruit after arriving in their host plant habitat, behavioral responses to colored models were observed in a laboratory flight chamber. Host‐seeking females oriented themselves preferentially towards bright orange spheres (3.7 cm in diameter), irrespective of their natal host fruit: tomato, bug weed, or black nightshade. Females oriented themselves preferentially towards the orange sphere when placed against a fluorescent yellow background as opposed to a black background, but the distribution of responses to the set of colored spheres did not vary significantly with background color. In a choice situation between bright orange spheres of various sizes (1.9, 3.7, and 7.5 cm in diameter), females landed preferentially on the bigger sphere. However, they preferred a yellow color when the latter was associated with two‐dimensional models, probably mimicking leaves. The attractiveness of orange spheres depended more on the proportion of reflected light in the spectral region around 610 nm than brightness of color in itself. Low light intensity significantly influenced the activity of the flies but not their visual preference. The strong response of females to bright orange spheres confirmed the importance of visual characteristics in short‐range mechanisms of host‐plant location in specialist insects. Responses to fruit visual stimuli are discussed relative to other Tephritidae, host‐finding strategy, and pest management.
