“…However, because the temperatures employed (10, 15.6, 21.1 ~ were combined with a long day, the results may have been affected by photoperiodic activation and they are not a good proof of the reported impact of temperature. Nechols et al (1983) later obtained the necessary evidence: at 12L : 12D the median times to emergence of September sample were 146, 120 and 18 days, respectively at the above temperatures.…”

“…1). In Choristoneura viridis low temperature is essential for survival during the long diapause (see next section), but it does not shorten the time spent in diapause within 14 to 35 weeks (Schmidt, 1977) Hogan, 1960Kalpage & Brust, 1974Mogi, 1981Deura & Hartley, 1982Sims & Munstermann, 1983Gregg, 1985Tsuji, 1958McLeod & Beck, 1963Stephen & Osgood, 1965Selander & Weddle, 1972Vinogradova, 1974Fedorenko, 1975Bell & Bowley, 1980Sieber & Benz, 1980Bartelt et al, 1981Baker, 1982Baxendale & Teetes, 1983Rock & Shaffer, 1983McNeil & Fields, 1985Fraenkel & Hsiao, 1968Denlinger, 1972Bodnaryk, 1977Nechols et al, 1983Sims & Shapiro, 1983De Wilde, 1969Tauber & Tauber, 1973aSheldon & MacLeod, 1974Elsey, 1974Hodek, 1974Lumme et al, 1974Wellso, 1974Minami et aL, 1979Solbreck & Sill6n-Tullberg, 1981Tadini et al, 1982McGiffen & Meyer, 1986 TDmwr ae -2 _ listed by Tauber et al (1986) and/or Danks (1987), respectively. inhabitants of regions with mild winter.…”

The review emphasizes that there are multiple pathways to diapause completion. The programmed course of events is modified by environmental cues. Often chilling is not a prerequisite for the completion of hibernation diapause (examples tabulated). Diapause completion progresses well at intermediate or high temperatures, sometimes it is even stimulated by high or increasing temperature. Low temperatures are important, as they (1) conserve metabolic reserves, (2) prevent resumption of post‐diapause morphogenesis and thus synchronize the life‐cycle, (3) represent contrast to the later increase in temperature. Diapause consists of phases with different prerequisites. There is a principal difference between diapause development and photoperiodic activation as indicated by the subsequent physiological condition of insects.

“…Photoperiod, a relatively noise-free seasonal cue, is widely used among insects as the primary factor signaling initiation and maintenance of diapause. In Agromyzidae, the roles of temperature and photoperiod in the regulation of pupation and diapause have been studied in detail in Agromyza frontella (Dipt., Agromyzidae) (MELLORS and HELGESEN 1982;NECHOLS et al 1983;TAUBER et al 1982;THERRIEN et al 1985). These studies suggest photoperiod as the single major stimulus for the initiation of diapause.…”

“…This can cause large interpopulation differences in the developmental stage of host plants although photoperiod is the same in all populations (FREY 1986). Thus, a temperature-based regulation of diapause allows for very close synchronization of mono-or oligophagous insects with the phenology of their host plant as shown, e. g., for Laspeyresiu pornonella (Lep., Olethreutidae; PHILLIPS and BARNES 1975) and for Agromyza frontelkz (NECHOLS et al 1983).…”

Voltinism and diapause in the oligophagous leafminer Phytomyza chaerophylli (Kaltenbach) (Dipt., Agromyzidae)

Phytomyza cbaeropbylfi (Kaltenbach) is multivoltine with two distinct population density peaks per year, the first in sprin and the second in fall. The fly shows both a summer and a winter diapause, the most important cues for diapause regulation being temperature and photoperiod. Winter dia ause is maintained by low temperatures and short photoperiod. High temperatures can cause winter cfapause termination. Temperature can override the effect of hotoperiod in winter dia ause and seems thus to be the single most important signal for winter iapause maintenance an: termination. Summer diapause is maintained by high temperatures and long photoperiod. Short photoperiod can cause summer diapause termination. The relative importance of photoperiod seems to be more pronounced in summer than in winter diapause. Diapause regulation mechanisms provide this species with a high degree of flexibility in its life cycle and allow close adaptation to the phenology of specific host plant populations.Author's address: JURG E.

The vegetable leafminer, Liriomyza sativae Blanchard, poses a risk to vegetable and nursery production in mainland Australia since established in Cape York in 2015. Effective control overseas depends on maximising the impact of natural enemies. Problems with polyphagous Liriomyza pest species typically result from the destruction of their parasitoids by excessive use of non‐selective insecticides. Field studies are reviewed to identify parasitoid species involved in the biological control of L. sativae in open‐air and glasshouse production internationally and to assess the current knowledge of parasitoids of agromyzids in Australia. Overseas, invading Liriomyza populations have frequently been exploited by endemic parasitoids (often found on non‐pest agromyzid species), and non‐crop hosts have played a role as reservoirs of these parasitoids. The few published Australian field studies on the occurrence of agromyzid flies and their parasitoids show a large community of wasps attacking agromyzids, with species mainly from the Eulophidae, Pteromalidae and Braconidae. The most abundant recorded species are two cosmopolitan eulophid species, Hemiptarsenus varicornis (Girault) and Diglyphus isaea (Walker), and four Australian species: two eulophid species, Zagrammosoma latilineatum Ubaidillah and Closterocerus mirabilis Edwards & La Salle, one pteromalid species, Trigonogastrella sp., and one braconid species, Opius cinerariae Fischer, for which there is little biological information. One deficiency in the known assemblage in Australia is the absence of parasitoids from the Eucoilinae (Hymenoptera: Figitidae), a subfamily with several abundant species attacking agromyzids overseas. The composition and impact of the endemic parasitoid assemblage in Australia on populations of L. sativae needs to be assessed adequately in the field before the importation of additional exotic parasitoid species is contemplated. Overseas, two species, D. isaea and Dacnusa sibirica Telenga, are reared commercially for augmentative biological control, although the relatively high cost of production has restricted their release to protected cropping situations. Knowledge gaps remain locally about the taxonomy, distribution, host range and life cycle of parasitoids, and their potential impact on L. sativae.
