Insect behaviors are often influenced by light conditions including photoperiod, light intensity, and wavelength. Understanding pest insect responses to changing light conditions may help with developing alternative strategies for pest control. Little is known about the behavioral responses of leafhoppers (Hemiptera: Cicadellidae) to light conditions. The behavior of the tea green leafhopper, Empoasca onukii Matsuda, was examined when exposed to different light photoperiods or wavelengths. Observations included the frequency of locomotion and cleaning activities, and the duration of time spent searching. The results suggested that under normal photoperiod both female and male adults were generally more active in darkness (i.e., at night) than in light. In continuous darkness (DD), the locomotion and cleaning events in Period 1 (7:00–19:00) were significantly increased, when compared to the leafhoppers under normal photoperiod (LD). Leafhoppers, especially females, changed their behavioral patterns to a two day cycle under DD. Under continuous illumination (continuous quartz lamp light, yellow light at night, and green light at night), the activities of locomotion, cleaning, and searching were significantly suppressed during the night (19:00–7:00) and locomotion activities of both females and males were significantly increased during the day (7:00–19:00), suggesting a shift in circadian rhythm. Our work suggests that changes in light conditions, including photoperiod and wavelength, can influence behavioral activities of leafhoppers, potentially affecting other life history traits such as reproduction and development, and may serve as a method for leafhopper behavioral control.

“…Non-crop resources are sometimes enhanced to improve pest control, but the knowledge about the effect of those resources on pests is crucial before increasing their presence in the field in order to hamper pests performance (Baggen and Gurr 1998;Lavandero et al 2006;Winkler et al 2009a, b). Many studies analyzed the effect of different food resources (pollen, nectar, insect honeydews, and sugar solutions) on different natural enemies and on pests survival, reproduction, efficiency, or attractiveness (Jervis et al 1993;Baggen and Gurr 1998;Géneau et al 2012;AguilarFenollosa and Jacas 2013;Balzan and Wäckers 2013;Beltrà et al 2013;Gonzalez et al 2015;Saeed et al 2015). However, knowledge about the use of non-crop resources by most of the adult pests is still insufficient and as far as we know it has never been studied for the olive moth, Prays oleae (Bernard) (Lepidopteta: Praydidae).…”

Are wild flowers and insect honeydews potential food resources for adults of the olive moth, Prays oleae?

The use of non-crop resources by natural enemies and their potentialities to enhance their effectiveness as pest control agents is increasing as a method for conservation biological control. Nevertheless, the effect of consumption of non-crop resources by pests has been generally overlooked being this knowledge crucial to favor natural enemies but not pests. In the present work, insect honeydews and flowers suitability as food resources for the olive tree key-pest Prays oleae were analyzed under laboratory conditions. The selected honeydews were excreted by Saissetia oleae and Euphyllura olivina, two olive pests, and the selected plants were seven abundant species in the olive grove agroecosystem that bloom simultaneously with the flight period of the anthophagous generation of P. oleae. In this work, some of these resources were identified as potential food sources for P. oleae. Despite the general findings, which indicate that honeydews have less nutritional value for insects than nectar, P. oleae reached the best survival and reproduction performance with the insects' honeydews. Several of the tested flowers were identified as potential food resources for P. oleae, being Malva sylvestris the one that originated the best performance. Moreover, our results suggest that P. oleae females are synovigenic and emerge with nutritional reserves for reproduction. We highly recommend accomplishing further research before establishing these resources in biological control methods in order to confirm their effect on pests in fields.

“…The management of these wild hosts may provide an ecological approach to control D. suzukii through a better understanding of its behaviour and biology, potentially restricting population development adjacent to crops and reducing infestation. An improved understanding of how this pest uses the surrounding landscape could allow us to limit the local carrying capacity (Clementine et al ., ; Saeed et al ., ), reduce the probability of insecticide resistance (Mallet & Porter, ; Livingston et al ., ) and target areas of release for potential biological control agents (Daane et al ., ; Wang et al ., ). Using cultural control techniques on farms in combination with chemical control represents a realistic way of reducing the expansive population pressure on a local scale (Prokopy & Kogan, ).…”

Wild host plants in the landscape surrounding fruit farms may significantly influence the movement and population of the polyphagous and invasive pest Drosophila suzukii. Across 2 years, we sampled wild hosts adjacent to 10 blueberry farms in Michigan, U.S.A. We found five commonly infested wild fruits. Honeysuckle was a particularly abundant early season reproductive host. Consequently, six blueberry farms with honeysuckle at the margin were evaluated further. At each farm, nonhost plants and honeysuckle were monitored for larval and adult D. suzukii. The season‐long abundance of D. suzukii adults and early‐season infestation was highest near and within honeysuckle. In 2017, we tracked the movement of D. suzukii between honeysuckle and blueberries in early and late season using a protein immunomarking technique. Of the 1881 flies captured in our study, 7.1% were marked and their distribution pattern was even throughout the farm. Moreover, early season flies were less likely to remain in the marked host compared with late season flies. The findings of the present study highlight the importance of wild hosts on local pest pressure from D. suzukii and suggest that wild host management should be considered as part of integrated strategies for reducing the economic impacts of this pest.
