The Effect of Soil Type and Moisture Level on the Development of Lucilia sericata (Diptera: Calliphoridae).

Abstract

The present study aimed to determine the effects of the soil type and the moisture contents on the some life-history parameters of Lucilia sericata (Meigen, 1826) (Diptera: Calliphoridae). The larval and pupal survival, duration of development periods, and the weight of pupae and adult of L. sericata were examined at three different types of soil (clay, loamy, and sandy) with five moisture contents (0, 25, 50, 75, 100%). The post feeding L. sericata larvae were transferred to a plastic cup filled with soils with different moisture content, and all cups were kept at 27°C, 65% RH, and a photoperiod of 12:12 (L:D) h. In this article, the effects on some life-history parameters were compared with a two-way analysis of variance (ANOVA). Accordingly, the findings of this article indicate that moisture contents of soils and soil type have a significant effect on the development time of L. sericata. Furthermore, it has been found that larvae can survive on extremely wet substrates (75-100% humidity), although their development time is longer than other moisture content. Pupal and adult weight was significantly different among soil type and soil moisture. Our results provide a reference information for sufficient estimation of the effects of changes in moisture-related to soil type or climate on studies of forensic and biological control of L. sericata.
