“…Relevant theory has been reviewed many times (e.g. Wigglesworth, 1972;Laudien, 1973;Marshakov, 1984;Wagner et al, 1984a;Danks, 1987), and a variety of models for development continue to be presented (e.g. Logan et al, 1976;Sharpe & DeMichele, 1977;Taylor, 1981;Regniere, 1982Regniere, , 1984Hilbert & Logan, 1983;Wagner et al, 1984bWagner et al, , 1985Hil bert, 1995;Lactin et al, 1995).…”

Abstract. Some previous work on arthropod development is insufficiently detailed or incompletely reported. Much of the published information in this area is of limited use for the general analysis of life cycles. These difficulties arise primarily because many experiments do not control fully for the strain of the material (and even its specific identity) nor for rearing conditions, do not ade quately take account of the complexity of life cycles and their stages, or are restricted to only part of the life cycle. For example, 285 such factors as variable numbers of instars, sexual differences, abbreviated or hidden stages and dormancies may mean that the "average durations" reported apply to an unknown mixture of developmental types. Nor are experiments always designed or results reported and analysed in a logical and transparent manner. Undefined terms may obscure what actual developmental intervals were measured. Highly derived developmental or demographic measures may obscure core data. Statistical information may be inade quate. Such pitfalls are reviewed here, suggesting ways to ensure that results on the duration of development are both valid for spe cific studies and more widely useful. General experimental difficulties, recommended background information that should be provided, recommended life-cycle intervals and their terminology, and recommended ways to report numerical and statistical infor mation are briefly summarized in tabular form.

“…Large aggregations of dipteran larvae (maggot masses) develop heat due to their frenetic activity and fast metabolism, thus raising the micro environmental temperature [14]. The relationship between insect development and temperature has been well-established [15][16][17][18].…”

Lucilia cuprina is one of the forensically important Calliphoridae fly. L. cuprina is a helpful resource at the crime scenes as well as a nuisance to sheep. It is known to be one of the first flies to occupy a corpse upon its death. Due to this, it has great importance in forensic field to find out post-mortem interval. In this study, the development of L. cuprina is studied in an incubator at different constant temperatures. Larvae of the L. cuprina were reared in an incubator at 20 º C, 25 º C, 30 º C, 35 º C, and 40 º C. During study the developmental data, temperature and relative humidity of the rearing room as well as weight, length of the larvae were recorded from the time the larvae were collected until the adult flies emerge out.Results obtained show that development of the L. cuprina was slow at lower temperature. At the high temperature, developmental rate was fast. At low temperature L. cuprina attained greatest body weight whereas at high temperature there was a decrease in the weight. When flies were reared at 40 º C the development of the fly was much more rapid but slight mortality was observed. Above study shows that temperature plays a very important role in the development of L. cuprina. For the correct estimation of post-mortem interval this study is very useful, because each dipteran fly has its own developmental period with respect to temperature and region.
