“…Other studies report that trap color affects capture of lady beetles, bees (especially bumble bees), and moths (e.g., Hendrix and Showers 1990, Gross and Carpenter 1991, Meagher and Mitchell 1999, Clare et al 2000, Stephen and Rao 2005, Weber et al 2005, Mori and Evendon 2013, Kemp and Cottrell 2015. Specifically, lady beetles have a low response rate to green wavelengths (490-530 nm) (Rodriguez-Saona et al 2012, Jiuxuan et al 2013Kemp and Cottrell 2015). Bees, in general, are attracted to yellow wavelengths (550-580 nm), although how bees respond to color is still being studied, as color preferences can vary among Apidae (Stephen and Rao 2005).…”

Pheromone Lure and Trap Color Affects Bycatch in Agricultural Landscapes of Utah

Aerial traps, using combinations of color and attractive lures, are a critical tool for detecting and managing insect pest populations. Yet, despite improvements in trap efficacy, collection of nontarget species ("bycatch") plagues many insect pest surveys. Bycatch can influence survey effectiveness by reducing the available space for target species and increasing trap screening time, especially in areas where thousands of insects are captured as bycatch in a given season. Additionally, bycatch may negatively impact local nontarget insect populations, including beneficial predators and pollinators. Here, we tested the effect of pheromone lures on bycatch rates of Coccinellidae (Coleoptera), Apoidea (Hymenoptera), and nontarget Lepidoptera. Multicolored (primarily yellow and white) bucket traps containing a pheromone lure for capturing one of three survey target species, Spodoptera litura (F.), S. littoralis (Boisduval), or Helicoverpa armigera (Hübner), were placed in alfalfa and corn fields, and compared to multicolored traps without a pheromone lure. All-green traps with and without H. armigera lures were employed in a parallel study investigating the effect of lure and trap color on bycatch. Over 2,600 Coccinellidae representing seven species, nearly 6,400 bees in 57 species, and >9,000 nontarget moths in 17 genera were captured across 180 traps and seven temporal sampling events. Significant effects of lure and color were observed for multiple taxa. In general, nontarget insects were attracted to the H. armigera lure and multicolored trap, but further studies of trap color and pheromone lure specificity are needed to better understand these interactions and to minimize nontarget captures.

“…Some studies have shown that the phototactic behavioural responses of insects are activated within a certain range of light intensity, while intensities out of the optimal range are inhibitory (Chen et al, 2009(Chen et al, , 2012Roberts, Syms, & Goodman, 1992;Wei et al, 2000;Zhou, Kuang, Chen, Wang, & Liu, 2013). Movement of P. aphidis increased in our assays at low light intensity and decreased Biocontrol Science and Technology 1477 above that range for UV and blue light.…”

We investigated the spectral sensitivity and response to light intensity of Pachyneuron aphidis (Hymenoptera: Pteromalidae), which is a common hyperparasitoid of Aphidius gifuensis (Hymenoptera: Braconidae), a key natural enemy of the green peach aphid, Myzus persicae (Hemiptera: Aphididae). To do so, we used 15 monochromatic lights (emitting various specific wavelengths from 340 to 649 nm) and white light. P. aphidis adults are diurnal insects that show a positive phototaxis to a broad spectrum of light. Significant differences were found between sexes in the phototactic responses of P. aphidis to different monochromatic lights. Female P. aphidis showed four peaks of sensitivity at 380, 450, 504 and 589 nm. Male P. aphidis show two peaks of sensitivity, one at 450 nm and second at 628 nm. P. aphidis adults showed an increased phototactic response at low intensities and a decreased phototactic response at high intensities for both UV light and blue light. This experiment will help provide a scientific basis for the development of colour traps for insect pest management.

“…Previous studies investigated the phototactic behaviour of ladybirds to different wavelengths and have reported light response variability among different species and insect physiological status. In laboratory conditions, Coccinella septempunctata L. (Coleoptera: Coccinellidae) exhibited positive phototactic behaviour toward UV and red lights and much lower response to green or blue lights [ 63 ]. Notwithstanding, captures by blacklight UV traps in field trials were sporadic for several ladybird species, including C. septempunctata [ 64 ].…”

Capture strategies for the brown marmorated stink bug, Halyomorpha halys (Hemiptera: Pentatomidae), are challenging. Here we developed and evaluated a multimodal trap which combines visual and olfactory stimuli. Visual stimuli consisted of LEDs emitting UV-A and visible light. Olfactory stimuli were comprised of the synthetic aggregation pheromone and odours from trapped H. halys individuals. Stink bug attraction at different wavelengths was evaluated in laboratory two-choice bioassays, and different prototypes of the trap were tested in 2021 in natural, agricultural, and urban settings. Traps with a combination of UV-A and blue or green visible wavelengths provided higher H. halys attraction (up to ~8-fold) compared to traditional sticky or small pyramidal traps. The concurrent presence of synthetic pheromone and LED had a synergistic effect on H. halys positive phototaxis. Further development and implementation of the multimodal trap is discussed for prospective use in attract-and-kill or push–pull strategies.
