Optimal hatching conditions of Zophobas atratus (Coleoptera: Tenebrionidae) eggs under various culture conditions
2021, Journal of Asia-Pacific EntomologyCitation Excerpt :In their research on suitable temperature conditions for the breeding of Protaetia brevitarsis (Coleoptera: Cetoniidae), Kim et al. (2018a) found that the species larval weight increased at 27.5 °C; however, no difference was detected between larvae reared under 27.5 °C and 30 °C. Photoperiod is the primary cue in oviposition and hatching (Tauber, 1986), and many physiological changes are invoked in response to photoperiod alteration (Tanaka et al., 1993; Miles et al., 1998; Nakao, 1998; Ishihara, 2000). The willow leaf beetle, Plagiodera versicolora (Coleoptera: Chrysomelidae), overwinters as an adult in diapause.
Light pollution is a driver of insect declines
2020, Biological ConservationCitation Excerpt :For example, many insect species synchronize certain developmental activities with particular times of day: for example, Drosophila jambulina fruit flies eclose before dawn when ambient temperature and humidity are optimal (Thakurdas et al., 2009), while intertidal midges (Pontomyia oceana and Clunio spp.) eclose during periods of low tide (Neumann, 1989; Soong et al., 2011); improper timing could cause fruit flies to desiccate and intertidal midges to drown. Artificially lengthened photoperiods delay the development of insects that overwinter as juveniles, including locusts (Locusta migratoria; Tanaka et al., 1993) and thrips (Megalurothrips sjostedti; Ekesi et al., 1999), while accelerating the development of multivoltine lady beetles (Coelophora saucia; Omkar and Pathak, 2006), aphids (Megoura viciae; Kehoe et al., 2018) and flower bugs (Orius sauteri; Wang et al., 2013). By effectively lengthening photoperiod, and potentially suppressing melatonin production, ALAN prolongs juvenile development in black field crickets (Teleogryllus commodus; Durrant et al., 2018), but accelerates development in orb-web spiders (Eriophora biapicata; Willmott et al., 2018).
Adaptive significance of precocious pupation in the bean blister beetle, Epicauta gorhami (Coleoptera: Meloidae), a hypermetamorphic insect
2017, Journal of Insect PhysiologyCitation Excerpt :The present study was carried out to address these questions. In several studies, environmental control of seasonal development in insect species has been examined by rearing the insects under quasi-natural conditions in different seasons (e.g. Tanaka et al., 1993; Tanaka and Uemura, 1996; Teraoka and Numata, 1995; Musolin et al., 2001; Pfenning et al., 2007; Shintani, 2011; Shintani et al., 2015). In the present study, we reared E. gorhami larvae in different seasons to examine how the reaction norm plays a role in control of seasonal development, and consequently, we investigated whether a bivoltine life cycle is possible in nature for this beetle.
Adaptive difference in daily timing of hatch in two locust species, Schistocerca gregaria and Locusta migratoria: The effects of thermocycles and phase polyphenism
2015, Journal of Insect PhysiologyCitation Excerpt :Although strain-dependent effects might be expected, it was preliminarily confirmed that the hatching time of the albino strain was not significantly different from that for two normal (pigmented) strains from Tsushima Island and Minami-Daito Island under 12 h-thermocycles of 35 and 20 °C (Nishide, Y. and Tanaka, S., unpublished observations). In the gregarious colony of each species, groups of approximately 100 individuals were reared in large wooden-framed cages (42 × 24 × 42 cm) covered with nylon screen, whereas solitarious locusts were individually reared in small wooden-framed cages (28 × 15 × 28 cm) except for a short period for mating according to the method previously described (Tanaka et al., 1993). The desert locusts were reared at 31 ± 1 °C with a photoperiod of 16L:8D and the migratory locusts were reared at 30 ± 1 °C with a photoperiod of 12L:12D.
Locust Phase Polyphenism: An Update
2009, Advances in Insect PhysiologyCitation Excerpt :Photoperiod affects fecundity in certain species or geographic strains, and the effect of photoperiod may be density-dependent, as in the case of the ‘Palavas’ strain of L. migratoria (Verdier, 1967); in dense populations of this strain, maturation is inhibited under long days, whereas in isolated females it is not so inhibited. Moreover, in some instances, fecundity is affected by interactions between photoperiod, temperature and density, as in a Japanese strain of L. migratoria (Tanaka et al., 1993). Norris (1950) investigated density-dependent differences in the rate of oviposition and in the total number of egg pods laid by L. m. migratorioides during the female's lifetime in the laboratory.
