“…Without control efforts, it can damage up to two-thirds of a strawberry crop [ 33 ]. L. lineolaris overwinters in protected areas including leaf litter, hedgerows, or plant debris [ 34 ] and higher densities have been observed in blueberry and tomato fields with wildflower borders [ 16 , 35 ]. Alternatively S. geminata , a fruit-feeding specialist, does not appear to benefit from wildflower plantings [ 16 ].…”

Increased homogeneity of agricultural landscapes in the last century has led to a loss of biodiversity and ecosystem services. However, management practices such as wildflower borders offer supplementary resources to many beneficial arthropods. There is evidence that these borders can increase beneficial arthropod abundance, including natural enemies of many pests. However, this increase in local habitat diversity can also have effects on pest populations, and these effects are not well-studied. In this study, we investigated how wildflower borders affect both natural enemies and pests within an adjacent strawberry crop. Significantly more predators were captured in strawberry plantings with wildflower borders versus plantings without wildflowers, but this effect depended on sampling method. Overall, herbivore populations were lower in plots with a wildflower border; however, responses to wildflower borders varied across specific pest groups. Densities of Lygus lineolaris (Tarnished Plant Bug), a generalist pest, increased significantly in plots that had a border, while Stelidota geminata (Strawberry Sap Beetle) decreased in strawberry fields with a wildflower border. These results suggest that wildflower borders may support the control of some pest insects; however, if the pest is a generalist and can utilize the resources of the wildflower patch, their populations may increase within the crop.

“…Lygus bugs also invade other host plants during the reproductive stages of plant growth and normally prefer to oviposit and feed on host plants with buds and flowers or with growing tips and young foliage (Phillips and DeRonde 1965; Hauschild and Parker 1976;Tugwell et al 1976;Boivin et al 1981;Fleischer and Gaylor 1987;Bostanian 1994). In addition, the development of Lygus populations on the reproductive structures has been reported for beans (Khattat and Stewart 1975), cotton (Tugwell et al 1976), strawberries (Bostanian 1994), and weeds (Boivin et al 1981;Khattat and Stewart 1980). 1-5.5, Harper and Berkenkamp 1975).…”

“…Similarly, in northern Alberta, the start of the reproductive stages of canola was the main factor influencing the time of invasion of adults of overwintered-generation Lygus (Butts and Lamb 1991), even though these adults were from a different generation and were from populations that likely developed on different host plants than first-generation adults. Lygus bugs also invade other host plants during the reproductive stages of plant growth and normally prefer to oviposit and feed on host plants with buds and flowers or with growing tips and young foliage (Phillips and DeRonde 1965; Hauschild and Parker 1976;Tugwell et al 1976;Boivin et al 1981;Fleischer and Gaylor 1987;Bostanian 1994). The maximum and median abundances of the five nymphal instars and secondgeneration adults of L. lineolaris, L. elisus, and L. borealis were reached during the ripening stages of plant development (pod development stages 5.1-5.5, Harper and Berkenkamp 1975).…”

The Canadian Entomologist 129: 777 -787 (1997) The development of adult and nymphal populations of Lygus lineolaris (Palisot de Beauvois), L. elisus Van Duzee, and L. borealis (Kelton) was studied in relation to seeding date and stage of plant development in four seedings of canola (cv. Westar) in field plots at Glenlea, Manitoba, in 1988 and 1989. Lygus lineolaris was the dominant species in all seedings and in both years. Colonizing adults (first-generation adults) of the t h e e Lygus spp. first invaded the plots at about the same time from the late rosette to the early flowering stages of plant development, and Lygus adult numbers reached maxima during flowering in all seedings. The stage of plant development, and not seeding date, was important in attracting colonizing adults of Lygus to canola. Second-generation nymphs first appeared at the flowering stage of canola. All nymphal instars reached maxima and median abundances during the late flowering and pod development stages in all seedings. Second-generation adults were present from early to late pod development stages. Median abundances of second-generation adults of L. lineolaris, L. elisus, and L. borealis usually were reached at the same plant growth stage in each seeding. Leferink, J.H.M., et G.H. Gerber. 1997.

“…Overwintered adults resume activity at temperatures >8 8C and they feed on reproductive parts of plants (i.e., buds of flowers) or rapidly growing meristematic tissues (Bostanian 1994). Once the host becomes lignified, they migrate to other annual plants that have meristematic tissues.…”

Nymphs and adults of the tarnished plant bug (Lygus lineolaris (Palisot de Beauvois)) feeding on grapevine were videorecorded in the laboratory to determine the short-term impact of feeding punctures at various phenological stages. Feeding behaviour was significantly different between nymphs and adults in the number of punctures but not in the feeding time spent. Observations by light and scanning electron microscopy showed that, from phenological stages B (bud burst) to F (visible cluster), feeding did not cause plant damage and injuries did not impact the meristems, which were coated with viscous or filamentous pectin. During phenological stages H (florets separated) and I (flowering), feeding was restricted to nectar glands, and as there is no functional relationship between nectaries and ovaries, feeding had no impact on normal development of ovaries. In later phenological stages J (berry set) to L (cluster closure, berry touch), most damage was on the pedicels of berries. Pedicels attacked at the next phenological stage show no evidence of injuries. Grapevine appears to tolerate punctual feeding made by this insect; damage is minimal and berry production is not threatened.Résumé : Des nymphes et des adultes de punaise terne (Lygus lineolaris (Palisot de Beauvois)), se nourrissant sur de la vigne, ont été filmés en laboratoire pour déterminer l'impact à court terme de la prise de nourriture ponctuelle durant divers stades phénologiques. Le comportement nourricier était significativement différent entre les nymphes et les adultes, pour le nombre de perforations, mais pas pour le temps passé lors de chaque piqûre. Les observations en microscopies électronique à balayage et optique montrent que, des stades phénologiques B (bourgeon dans le coton) à F (grappes visibles), les piqûres n'atteignent pas les méristèmes, ces derniers étant enrobés de pectine visqueuse ou filamenteuse. Durant les stades phénologiques H (boutons floraux séparés) et I (floraison), la prise de nourriture était restreinte au disque nectarifère et, comme il n'existe aucune relation fonctionnelle entre les nectaires et l'ovaire, les dommages ne présentaient aucune incidence sur le développement ultérieur du fruit. Des stades phénologiques J (nouaison) à L (fermeture de la grappe), les dommages sont principalement situés sur le pédicelle des baies. Ces pédicelles, attaqués et examinés au stade phénologique suivant, ne montraient aucune trace de blessure. La vigne tolérerait les piqûres ponctuelles faites par cet insecte; les dommages sont minimaux et la production de baies n'est pas réduite.
