“…Leisnham et al (2011) reported photoperiod as a factor affecting inter-population differentiation in the survival and diapause of Aedes albopictus (Skuse) (Diptera: Culicidae). Exposure to short photoperiods during the early adult stage was necessary to induce diapause in 50% of the population of Orius insidiosus (Say) (Heteroptera: Anthocoridae), and the short photoperiod served to maintain diapause in adult females (Ruberson et al 2000). Although we found a positive correlation between a shorter photoperiod and disappearance of O. agamemnon arabicus adults from the Þeld, we cannot conÞrm that either adults or other life stages enter diapause during the winter.…”

Oryctes agamemnon arabicus (Fairmaire) (Coleoptera: Scarabaeidae) is a date palm insect pest that causes damage to trunk and roots and can damage grass lawns in the United Arab Emirates (UAE) and other countries such as Oman, Saudi Arabia, and Tunisia. The goal of this study was to monitor population dynamics and to evaluate six light colors (white, green, red, yellow, blue, and infrared) and two lamp types (mercury and energy-saving) in light traps. Experiments were performed on a date palm farm during a 2 yr period (2010 and 2011). It was found that this insect is a univoltine pest with a single population peak. Adults appeared in the field around middle of April and early May and the population continued to build until maximum numbers were reached in mid June. No adults were found after the end of September. Photoperiod showed a significant correlation with the changes in adult population size. White light emitted from mercury lamps attracted significantly more O. agamemnon arabicus adults compared with the other tested light colors. Increasing the wattage of mercury lamps from 160 to 250 watt did not significantly increase the number of collected insects. The results demonstrated that light traps equipped with 160-watt mercury lamps emitting white light collected significantly the highest number of this insect among the other tested lamps.

Orius insidiosus clearly demonstrates reproductive diapause (Ruberson et al 1991(Ruberson et al , 1998(Ruberson et al , 2000, a strategy for survival in temperate climates. Historical observations imply that O. pumilio is a tropical species (Henry 1988;Carpintero 2002), but it has not yet been studied regarding diapause status.…”

“…For a high incidence of diapause, exposure of a certain sequence of instars plus the adult stage to short day length is required for the Orius species studied so far (van den Meiracker, 1994;Ruberson et al, 2000;Cho et al, 2005). The exposure of adults is indispensable for all species, but the number and sequence of nymphal instars that should be exposed differs from one species to another.…”

“…Proper timing and follow-up for greenhouse releases of Orius that undergo diapause necessitate the determination of the life stages that are sensitive to diapause-inducing photoperiods (Ruberson et al, 2000). Available data on the photoperiodic sensitivity of different life stages in Orius were obtained using single temperature regimes only (van den Meiracker, 1994;Ruberson et al, 2000;Cho et al, 2005).…”

The photoperiodic sensitivity and storage of Orius majusculus (Reuter) from Antalya was investigated to obtain data for the optimization of its release. In the current study, it was not possible to induce a high (up to 100%) incidence of diapause unless all the nymphal instars and adults were successively exposed (i.e. full exposure) to a short day length (11.5 h) at constant temperatures of 18 and 26 °C, and fluctuating temperatures of 10/26 °C. Hence an intermittent exposure to long day lengths, even for short periods of time (only during instars IV-V or adult stage), would avoid a high incidence of diapause at 10/26 °C and 26 °C. The response of O. majusculus nymphal instars and adults to a short day length with a low incidence of diapause under fluctuating temperatures suggests that greenhouses, where such temperatures prevail, provide an environment that is conducive to diapause prevention. The release of adults is a better approach than the release of nymphs, since the adults and their nymphs, until the eclosion of new adults, are expected to respond to short day lengths with a low incidence of diapause in greenhouses. When nymphs are released, on the other hand, a high incidence of diapause would be inevitable. Increasing the constant temperature to 30 °C at full exposure did not prevent diapause and consequently did not change the incidence of diapause. Storage of diapausing O. majusculus adults was possible for 1 month with a higher survival rate and fecundity than in a study based on the storage of nondiapausing adults at a lower temperature.
