“…We did not find any synergetic effect of UV light and bisexual lure neither in the laboratory tests nor in the field. This result was somehow surprising, since in some cases light and odor attractant together produce stronger effect than each of stimulus alone (Frolov, 2022). For example, western flower thrips, Frankliniella occidentalis (Pergande), was attracted to the combination of a commercial semiochemical lure for thrips and blue LED (445 nm) better than to light and odor alone (Otieno et al, 2018).…”

The European corn borer, Ostrinia nubilalis (Hubner), relies on multimodal sensory information to find food, mates, mating and ovipositional grounds. Successful phytosanitary monitoring demands for the bait for the field traps to obtain the most reliable representation of pest abundance. Attraction to light and blend of key components of host plant odor, was tested both in the laboratory and field conditions. Ultraviolet light, which was the most effective in the wind tunnel experiments, was further tested in the field alone and in combination with bisexual lure. Bisexual lure, being attractive in the lab, as well as in the field, did not improve responses to ultraviolet in both experimental designs. All three baits attracted significantly more females than males in the field. Wind tunnel experiments revealed that ultraviolet elicited the shortest response latencies either alone or paired with the odor bait. The lack of synergistic effect between attractive light and odor stimuli is an important issue for pest monitoring. The possible reasons for the observed lack of synergy are the hierarchy of behavioral responses to different stimuli or the intensities of both stimuli are critically important for attractivity of combined stimulus and differ from separately presented ones.

“…The development of novel LTs has blossomed in recent years (Table 1) with the advent of light emitting diodes, solar-powered energy sources, and intelligent designs [13,18,26,70,71,[73][74][75], leading to a renewed interest in LT mt . The high rate of innovation in designing LTs for insect control is not problematic per se; after all, improvements in trap design have been an intrinsic part of LT development since early inception [9].…”

“…The mechanisms influencing the response of insects to light sources [circadian rhythms and photoperiod; the physiology of flight-to-light, including moon/abiotic/environmental effects; and interspecific variation in attraction to light attributes] have already been thoroughly reviewed [8][9][10][11][12][13] and deemed outside the scope of this study. In this context, variable captures in LTs with different light sources are not accounted for in Tables 1 and 2, i.e., 'a trap is a trap'.…”

“…Because many insect species across all major taxonomic orders are attracted to LTs [12][13][14]31,32,35,41,53,73,82,83], mass trapping programs are designed with light sources that predominantly capture key target pests and reduce the attraction of beneficial insects. The problem can be approximated with a redefined optimal trap design d j associated with the highest ratios of target pests to beneficial insects (n p /n b ):…”

“…The research output was low worldwide between 1975 and 2010 Unbeknown to many entomologists, the successful control of Lepidopteran agricultural pests is often achieved with LTs, either to suppress/eradicate isolated populations (the sustained deployment of LTs over multiple generations) [4][5][6] or reduce short-term pest damage by culling populations of reproductive adults (LT-based mass trapping per se, or LT mt ). The commonality of LT mt is highlighted by the large number of field trials testing the approach [7][8][9][10][11], pest management guidelines in multiple crops [12][13][14][15][16][17], and recent deployment of 170 million LT units to control agricultural pests in China [18].…”

The management of Lepidopteran pests with light traps (LTs) is often achieved by luring adults to death at light sources (light trap-based mass trapping, or LTmt). Large-scale LTmt programs against agricultural pests initiated in the late 1920s in the United States were phased out in the 1970s, coinciding with the rise of pheromone-based management research. The interest in LTmt has surged in recent years with the advent of light emitting diodes, solar power sources, and intelligent design. The first step in implementing LTmt is to identify a trapping design that maximizes the capture of target pests and minimizes the capture of non-target beneficial insects—with a cautionary note that high captures in LTs are not equivalent to the feasibility of mass trapping: the ultimate objective of LTmt is to protect crop plants from pest damage, not to trap adults. The captures of egg-carrying females in light traps have a greater impact on the efficiency of LTmt than the captures of males. When LTmt is defined as a harvesting procedure, the biomass of females in LTs may be viewed as the best estimator of the mass trapping yield; biomass proxy has universal application in LTmt as every living organism can be defined on a per weight basis. While research has largely focused on agricultural pests, an attempt is made here to conceptualize LTmt as a pest management strategy in forest ecosystems, using spruce budworm as a case study. The mass trapping of female budworms is impossible to achieve in endemic populations due to the large spatial scale of forest landscapes (implying the deployment of a prohibitively large number of LTs); in addition, ovipositing female budworms do not respond to light sources at a low density of conspecifics. The light-based mass trapping of female budworms may provide a realistic management option for geographically isolated forest stands heavily infested with budworms, as a tool to prevent tree mortality. Somehow unexpectedly, however, one factor obscuring the feasibility of LTmt is as follows: the complex (‘unknowable’) economic valuation of forest stands as opposed to agricultural landscapes.

Although the potential of the use of the semiochemicals (pheromones, allomones, kairomones, and synomones) and the semiophysicals (physical stimuli) to control insect behaviour for plant protection from harmful insects is beyond doubt, the characteristics of the interactions between their attractive properties have been extremely poorly studied. Therefore, despite the fact that the cotton bollworm, Helicoverpa armigera, is one of the most harmful insects on the planet, there is no information in the literature on the effect of a combination of light stimuli and a synthetic sex attractant (SSA) on the behaviour of this species. In July–August 2021–2023, we conducted a study in two locations in Krasnodar Territory of Russia to test attraction of cotton bollworm adults with traps placed on corn sowings and equipped with four baits: (1) ultraviolet light emitting diodes (UV LEDs), (2) SSA, (3) SSA + UV LEDs, and control (4). The results obtained showed significant differences between the baits in capturing moths: not a single adult was captured in the control trap at all; traps with UV LEDs captured about 8%; with SSA, capturing a little more than 30%, and traps that attracted insects with both SPA and UV LEDs captured almost 60% of the total number of moths captured. The small catch of moths to the light is clearly explained by the situation of the traps in rows of tall hybrid corn at a height of 1.5 metres above the ground and no closer than 30 metеrs to the edge of the field. This means that the light, unlike SSA signals, was faded rapidly by the surrounding vegetation. However, a positive aspect of the technique used is the absence of significant numbers of non-target insect species capture in traps. The only exceptions are green grasshoppers, Tettigonia caudata (Ch.) and T. viridissima (L.), in traps with LEDs or other baits. Using two-factor ANOVA of both the original and transformed (x + 0.5)½ capture data, we found a synergy effect in the interaction of SSA and LED signals with respect to attractiveness for pest adults at pa = 0.05 only in one out of the five tests conducted. This result shows that the interaction of the semiochemicals and semiophysicals has rather additive than synergistic nature. Nevertheless, the results of the tests suggest that the combined use of SSA and LED may be a promising means for controlling the behaviour of the pest since retrofitting pheromone traps with UV LEDs can result in an approximately twofold increase in catch rates of the cotton bollworm adults.
