Development, reproduction and longevity of Orius minutus and Orius sauteri (Heteroptera : Anthocoridae) when reared on Ephestia kuehniella eggs

Development, Prey Consumption, and Fecundity of Orius minutus (Heteroptera: Anthocoridae) when Fed on Tetranychus urticae (Acari: Tetranychidae)

“…They laid a total of 148.9 eggs within 28.5 days. These reproductive abilities were higher than those stated in a previous study when the Mediterranean flour moth Ephestia kuehniella Zellar was commonly used as prey (Honda et al, 1998;Kakimoto et al, 2005). O. minutus laid only 1.9 eggs daily and 94.5 eggs in total when fed on the eggs of E. kuehniella, which was used for the mass production of Orius bugs (Kakimoto et al, 2005).…”

Comparison of the reproductive potential of three Orius species, O. strigicollis, O. sauteri, and O. minutus (Heteroptera: Anthocoridae), using eggs of the Mediterranean flour moth as a food source

“…It has been reported that dietary differences affect the longevity and fecundity of Orius species (Kiman and Yeargan, 1985;Bush et al, 1993;Chyzik et al, 1995 (Tommasini and Nicoli, 1993) and those of O. insidiosus fed on moth, Heliothis virescens (F.), eggs (Kiman and Yeargan, 1985) lived longer and laid more eggs than those fed on thrips: Frankliniella occidentalis (Tommasini and Nicoli, 1993) and Sericothrips variabilis (Beach) (Kiman and Yeargan, 1985). Honda et al (1998) and Yano et al (2002) also reported that Orius species collected in Japan produce more eggs when provided E. kuehniella eggs than with their natural hosts. Our results are consistent with these reports.…”

“…Thus, it is hard to attribute the occurrence of non-ovipositing females to diapause and decreased mating activity at low temperatures. According to Honda et al (1998), unmated females of O. sauteri and O. minutus lived longer than the mated females. However, our study showed that the longevity of non-ovipositing females is generally shorter than that of ovipositing females.…”

“…They also suggested that some nutrition contents in the diet might affect the fecundity of the bug. Many Orius species can be successfully reared on E. kuehniella eggs (Alauzet et al, 1992(Alauzet et al, , 1994Tommasini and Nicoli, 1993;Richards and Schmidt, 1996;Cocuzza et al, 1997;Vacante et al, 1997;Honda et al, 1998;Yano et al, 2002). However, the existence of non-ovipositing females is an important problem from the viewpoint of quality control in the mass-production of Orius species as a biological control agent.…”

Avaliação de substratos de oviposição para Orius insidiosus (Say) (Hemiptera, Anthocoridae)

“…No entanto, este substrato de oviposição muitas vezes apresenta contaminação por fungos e se decompõe antes dos ovos do predador terem completado seu desenvolvimento (Richards & Schmidt 1996). Outros substratos como hastes de feijão, folhas de algodão e pepino (Bueno 2000), folhas de feijão (Honda et al 1998), folhas de berinjela (Nagai & Yano 1999) e inflorescências de picão-preto Bidens pilosa L. ) têm sido testados. Entretanto, também foi verificado que esses materiais requerem considerável espaço para a sua produção ou são difíceis de produzir (picão-preto), o que aumenta o custo de produção do agente biológico, além de possibilitarem a introdução de patógenos e/ou resíduos de inseticidas na criação.…”
