“…Logan et al (1991) suggested selecting a nonlinear model that performs best at the temperatures that predominate in a region. Other authors have excluded data from the Þt of the regression equation to better represent the linear portion of the rate curve (Sanderson et al 1989, Roltsch et al 1990, Fan et al 1992, Judd and McBrien 1994. VanKirk and AliNiazee (1981) compared model parameters predicted by varying the set of experimental temperatures included in the analysis; they then developed a weighted regression method to minimize the subjectivity in selecting experimental temperatures and to develop a model for a speciÞc temperature regime.…”

“…Panels A1 and A2 use a heat-sum of 615 degree days for completion of one generation of the insect while in panels B1 and B2 use a temperature sum of 417.5 degree days. These temperature sums are averages of the values reported by Seaman and Barnes (1984) and Sanderson et al (1989b). Weather data are from the Copernicus Climate Change Service information.…”

Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest risk assessment of Amyelois transitella (Lepidoptera: Pyralidae), the navel orangeworm, for the EU. The quantitative assessment considered two scenarios: (i) current practices and (ii) a requirement for chilled transport. The assessment focused on pathways of introduction, climatic conditions and cultivation of hosts allowing establishment, spread and impact. A. transitella is a common pest of almonds, pistachios and walnuts in California, which is the main source for these nuts imported into the EU. Based on size of the trade and infestation at origin, importation of walnuts and almonds from the USA was identified as the most important pathways for entry of A. transitella. Using expert knowledge elicitation (EKE) and pathway modelling, a median estimate of 2,630 infested nuts is expected to enter the EU each year over the next 5 years (90% certainty range (CR) from 338 to 26,000 infested nuts per year). However, due to estimated small likelihoods of transfer to a host, mating upon transfer and survival of founder populations, the number of populations that establish was estimated to be 0.000698 year −1 (median, 90% CR: 0.0000126-0.0364 year −1 ). Accordingly, the expected period between founding events is 1,430 years (median, 90% CR: 27.5-79,400 year). The likelihood of entry resulting in establishment is therefore considered very small. However, this estimate has high uncertainty, mainly concerning the processes of transfer of the insect to hosts and the establishment of founder populations by those that successfully transfer. Climate matching and CLIMEX modelling indicate that conditions are most suitable for establishment in the southern EU, especially around the Mediterranean basin. The median rate of natural spread was estimated to be 5.6 km/year (median, 90% CR 0.8-19.3 km/year), after an initial lag period of 3.1 year (mean, 90% CR 1.7-6.2 year) following the establishment of a founder population. If A. transitella did establish, estimated median yield losses in nuts were estimated to be in the order of 1-2% depending on the nut species and production system. A scenario requiring imports of nuts to be transported under chilled conditions was shown to provide potential to further reduce the likelihood of entry.

“…Temperature-dependent models are widely used to predict population density and rate of development of insect pests and their natural enemies (Woodson & Edelson 1988, Hayakawa et al 1990, Deloach 1974, for example corn leaf aphid, Rhopalosiphum maidis (Elliott et al 1988), navel orange worm Amyelois transitella (Sanderson et al 1989), Mexican bean beetle Epilachna varivestis (Fan et al 1992), and the coccinellids Hippodamia sinuata (Michels & Behle 1991) and Stethorus bifidus (Petersons et al 1994). No data have been published on the Degree-Day (DD) requirement in the genus Stethorus, except for S. bifidus.…”

Influence of temperature on the development of the predatory ladybird, Stethorus vagans Blackburn, fed on Tetranychus urticae Koch was assessed at seven constant (10, 12, 15, 20, 25, 30 and 35 °C) and fluctuating (12.7-32.1 °C) temperatures. There was a strong positive correlation (r = 0.99) between rate of development and temperature. The development times from egg to adult emergence were 65.2±2.3 and 9.2±0.3 days at 12 and 30 °C constant, respectively and 15.4±0.3 days at fluctuating temperature. Average egg incubation period decreased from 16.5±0.8 to 2.18±0.2 days with increasing temperatures from 12 to 30 °C, respectively and was 4.1±0.3 days at the fluctuating temperature. Eggs did not develop at 10 °C; however, they could survive a long period of exposure to this temperature. None of two hundred eggs that were placed at a constant temperature of 10 °C for 60 days hatched; but when they were subsequently exposed to ≥ 15 °C, more than 120 of them hatched. Eggs appeared to develop normally at 35 °C, however, larvae died before or immediately after emergence. The lower development threshold temperature for egg, 1st, 2nd, 3rd, 4th larval instars, pupal and all these stages combined was 10.1, 9.5, 9.5, 9.1, 8.2, 8.0, and 9.1 °C, respectively. Degree-day (DD) accumulation was also calculated for each stage as well as for all stages combined. It was estimated to be 189.2±4.8 DD at 12 °C and 207.8±6.9 DD at 30 °C constant, respectively, and 189.1±5.0 DD at fluctuating temperatures.
