Reproduction and longevity of the anthocorid predators Orius laevigatus (Fieber) and Orius albidipennis (Reuter) (Heteroptera: Anthocoridae) were studied under controlled conditions in the laboratory. Three different diets were tested: eggs of the Mediterranean flour moth, Ephestia kuehniella Zeller, E. kuehniella eggs plus pollen, and pollen only. Small rooted plants of Spanish pepper (Capsicum annuum L. cv. 'Creta', long red) served as oviposition substrate and moisture source. In all treatments, total fecundity, oviposition period and female longevity of O. laevigatus were greater than that of O. albidipennis. When a diet of E. kuehniella eggs was supplemented with pollen, total fecundity of O. albidipennis was increased by about 40%. Female O. albidipennis fed only pollen laid five times less eggs than those fed flour moth eggs and pollen; also, longevity of females was shorter when only pollen was offered as food. Fecundity and longevity of O. laevigatus were not influenced when supplementing a diet of E. kuehniella eggs with pollen. Females of O. laevigatus receiving only pollen reduced egg production by about 60% but had a similar longevity as those receiving a diet including flour moth eggs. In either species, preoviposition period and egg hatch were not affected by diet. The ability of both anthocorids to use pollen as an alternative or additional food is discussed in relation to their practical use in integrated control programmes.

“…According to Ruberson et al (1991) and van den Meiracker (1994), species of Orius enter reproductive diapause when the pre-oviposition period exceeds 14 days. For Tommasini (2003), the pre-oviposition period is an indicator on how adult populations react to external stymuli.…”

“…did not observe sensibility of this predator to alternate photoperiods between pre-imaginal and adult phases. On the other hand, O. insidiosus has its reproduction altered by short photoperiods in temperate countries, resulting in reproductive diapause (Kingsley & Harrington 1982, Ruberson et al 1991, van den Meiracker 1994.…”

“…Tommasini & Nicoli (1996) found that strains of Orius laevigatus (Fieber) from North Italy tend to enter reproductive diapause while southern strains of this species can be used on thrips control in autumn and winter. Thus, low latitude strains may be of great value to biological control in greenhauses on high latitude regions (van den Meiracker 1994).…”

“…Under this system of cultivation, heteropterous of genus Orius Wolff are widely used on biological control of thrips in Europe, United States and Canada (van den Meiracker 1994, van Lenteren 2000, where reproductive diapause studies are made. Gillespie & Quiring (1993) found a decrease of approximately 3h in the critical day lenght when comparing Orius tristicolor (White) from Canada (49°N) and from California (38°N).…”

Influência do Fotoperíodo na Reprodução e Longevidade de Orius thyestes Herring (Hemiptera: Anthocoridae) RESUMO -Várias espécies de Orius Wolff são utilizadas no controle biológico de tripes em cultivos protegidos em regiões temperadas, entretanto algumas delas apresentam diapausa reprodutiva, comprometendo a atuação desses agentes de controle biológico. Não existem relatos sobre a biologia da espécie neotropical Orius thyestes Herring em diferentes condições ambientais. Este trabalho objetivou verificar a influência do fotoperíodo na reprodução e longevidade desse predador. Ninfas foram individualizadas em placas de Petri e mantidas em câmaras climatizadas a 28 ± 1°C, UR de 70 ± 10% e nos fotoperíodos de 12L:12E, 11L:13E, 10L:14E e 09L:15E. Os adultos foram acasalados em placas de Petri contendo inflorescência de Bidens pilosa L. Asteraceae como substrato de oviposição e ovos de Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) como alimento. Foram avaliados os períodos de pré-oviposição e oviposição, fecundidade e longevidade de fêmeas e machos. Em nenhuma das condições de fotoperíodos avaliadas O. thyestes apresentou diapausa reprodutiva. O número médio de ovos por fêmea diminuiu proporcionalmente ao número de horas de luz, com diferença (P < 0,05) entre os valores obtidos em 12h e 9h de luz. A longevidade de fêmeas e machos do predador sob fotofase de 9h foi menor (P < 0,05) que as longevidades observadas nos demais fotoperíodos testados. O conhecimento sobre a biologia do inimigo natural em diferentes condições permite otimizar a criação massal e prever o desempenho do predador em diferentes fotoperíodos que podem ocorrer ao longo do ano e no interior das casas de vegetação. PALAVRAS-CHAVE: Predador, fecundidade, fotofase, comportamento, controle biológico ABSTRACT -Several species of Orius Wolff are used in biological control of thrips in protected cultivations in temperate regions, but some of them show reproductive diapause, compromising the efficiency of these agents of biological control. There are no reports on the biology of the neotropical species Orius thyestes Herring under different environmental conditions. The purpose of this work was to investigate the influence of photoperiod on reproduction and longevity of this predator. Nymphs were kept in petri dishes in climatic chambers at 28 ± 1°C, 70 ± 10% RH and under the photoperiods of 12L:12D, 11L:13D, 10L:14D e 09L:15D. The mating adults were kept in petri dishes with Bidens pilosa L. Asteraceae inflorescences as oviposition substracts and eggs of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) as food. The pre-oviposition and oviposition periods, fecundity and longevity were evaluated and O. thyestes did not show reprodutive diapause in all photoperiod conditions established. The mean number of eggs obtained per female decreased with the reduction of the photophase, with a difference (P < 0.05) between the values obtained in 12h and 9h of photophase. Longevity of females and males under 9h photophase was shorter (P < 0.05) than in all...

BACKGROUND Pilophorus gallicus Remane (Hemiptera: Miridae) is an important predator of the pear psyllid Cacopsylla pyri L. (Hemiptera: Psyllidae) in pear orchards (Pyrus communis L. ‐Rosaceae‐). In the Mediterranean area, it has a multivoltine lifecycle, and can establish resident populations by entering into a facultative embryonic diapause to survive the winter season. Facultative diapause is regulated by environmental factors, and its role in population dynamics is essential because it determines the presence of active individuals in the field. The objective of this work was to investigate the effect of (i) photoperiod and temperature on diapause induction in P. gallicus and (ii) photoperiod, temperature, and exposure time on diapause termination. RESULTS Diapause induction was triggered by a short photoperiod (9L:15D), whereas temperature did not influence it significantly. In contrast, diapause termination required a prolonged exposure to low temperature while photoperiod did not have a significant effect. At 6 °C, diapause termination increased significantly between 50 and 70 days of exposure, but not among 70, 90 and 150 days. The longer the exposure of diapausing eggs to 6 °C the shorter their hatching times. Additionally, three different reproductive classes were observed among the female population: diapause inducing, non‐diapause inducing, and mixed. CONCLUSION This work contributes to the knowledge of the reproductive and overwintering strategy of P. gallicus. Embryonic diapause may greatly determine the structure of populations according to environmental conditions and the response of the predator as biological pest control agent. In addition, knowledge of the factors regulating egg diapause may be a useful tool for the mass rearing industry. © 2019 Society of Chemical Industry
