“…There are published data on the length of pre‐oviposition at a range of temperatures (17–29 °C) for L. lucorum (Men et al , ), and at three temperatures (12.8, 15.6 and 26.7 °C) for Lygus hesperus Knight (Strong & Sheldahl, ). The length of pre‐oviposition was also studied for L. rugulipennis at 25 °C in relation to various diets (Salerno et al , ); the results were similar to those of L. lucorum and L. hesperus at similar temperatures. Thus, we developed a model describing the length of oviposition in relation to temperature by combining the data from these studies:

R_{normali} = - 0.0395 + 0.0057 \cdot T

“…There were published data on the length of oviposition at a range of temperatures (17–29 °C) for a related species Lygus lucorum Meyer‐Dür (Men et al , ). The length of oviposition was also studied for L. rugulipennis at 25 °C in relation to various diets (Salerno et al , ) and the observed oviposition length was similar to that of L. lucorum at similar temperatures. Thus, a model was derived from the combined data of these two studies to describe the relationship of the length of oviposition with temperature:

R_{o} = 0.208 - 0.0147 \cdot T + 0.0003 \cdot T^{2}

“…The present model was developed primarily based on three published studies, two on L. rugulipennis (Easterbrook et al , ; Salerno et al , ) and one on L. lucorum (Men et al , ), as well as on unpublished data obtained at EMR, particularly on adults caught in early spring in the late 1990s and early 2000s. Although a web‐based system for pest and disease predictions in Norway (called VIPS) contains a model for L. rugulipennis , its actual formulation is unknown.…”

“…the length of oviposition period is 8 days); if T ≤ 8 °C, R o is set to 0.01, namely the female adult can only lay eggs for 100 days. This model does not consider post‐oviposition adult survival because it does not contribute to the phenology of the next generation and this period is much shorter than the oviposition period (Salerno et al , ).…”

“…where CV is the coefficient of variation in the developmental time for the process under consideration. Based on published (Easterbrook et al , ; Salerno et al , ) and unpublished studies at EMR at specific temperatures (J. D. Fitzgerald, unpublished data), CV ranged from approximately 0.1 to 0.2 depending on the developmental stage and/or temperature concerned. Thus, the estimated BN ranged from 25 to 100.…”

1 The European tarnished plant bug Lygus rugulipennis has caused significant economic damage to strawberry production in the U.K. in recent years. 2 Laboratory experiments were conducted to study L. rugulipennis development under fluctuating low temperatures. The results indicated that L. rugulipennis can develop at an appreciable rate at 10 • C. 3 We have developed a model predicting the phenology of L. rugulipennis in the U.K. The model assumes that adults overwinter and uses temperature from the first day of a calendar year to simulate pest development. The model was validated against field observations of L. rugulipennis population dynamics monitored under both open-field and protected conditions on weeds and strawberry plants. Predicted L. rugulipennis population patterns from the model agreed well with the observed data. 4The L. rugulipennis model can be used in practice to enable growers to identify the timing of the first generation of L. rugulipennis adult dispersal into strawberry, or other crops, from weeds. The model will also assist growers with the timing of the deployment of pheromone traps and interpreting the importance of trap catches. This will allow growers to better time and target applications of insecticides against damaging life stages of the pest.

Wind tunnel and vertical open Y-shaped olfactometer studies are used to test whether volatile cues from the host plant ( Vicia faba ), from conspecific bugs, and from a plant -conspecifics combination, would elicit behavioural responses in mated males and females of Lygus rugulipennis . In the olfactometer, females move towards volatiles from healthy plants but they do not respond to volatiles released by ovipositionand/or feeding-damaged plants without conspecifics, nor to conspecifics alone. Both in the wind tunnel and olfactometer, females respond to volatiles emitted by the plantinsect complex. By contrast, in the wind tunnel, both sexes move significantly towards damaged host plants, even if the presence of conspecifics on these plants enhances only the female response. However, the presence of eggs from conspecifics on host plants reduces the responses of both sexes in the wind tunnel. Finally, males, as well as females, are less responsive to conspecifics alone compared with damaged plants, especially when conspecifics are present on the host plants (host plant -Lygus complex). The results suggest that volatiles emitted by plants and conspecifics influence L. rugulipennis behaviour, giving information to both sexes on the presence of suitable host plants that have been colonized by other conspecifics acting as pioneers, or providing information on the presence of an already exploited host plant (presence of eggs), thus preventing competition. Males also can use this information to increase the probability of encountering mature females.
