Captive colonies of Bombus terricola Kirby received pollen for 8, 14, or 24 h/day. The effects of the treatment demonstrated experimentally the influence of larval nutrition on development time. The duration of the cocoon stage was positively related to both adult body size and pollen availability. The duration of the larval stage varied in a more complex way: within each treatment, duration of the larval stage was positively related to adult body size, but between the treatments, and for each of the three castes, pollen deprivation tended to lengthen the larval stage. These results reconcile divergent findings in the literature.

AbstractDrosophila suzukii Matsumura (Diptera: Drosophilidae) is a cosmopolitan polyphagous pest on unripe soft-skinned fruits. We sought to determine (1) temperature treatments that could be used to kill immature D. suzukii in fruit or packaging and (2) whether development on different fruits led to differences in cold tolerance of immature D. suzukii. We reared animals from egg on a banana-based laboratory diet and diets made of apple (Malus domestica Borkhausen; Rosaceae), blueberry (Vaccinium Linnaeus; Ericaceae), cherry (Prunus avium Linnaeus; Rosaceae), grape (Vitis Linnaeus; Vitaceae), orange (Citrus × sinensis (Linnaeus) Osbeck; Rutaceae), raspberry (Rubus Linnaeus; Rosaceae), or strawberry (Fragaria × ananassa Duchesne; Rosaceae) homogenate in agar and measured development time, adult body size, and cold tolerance. Diet type had complex effects on development time; in particular, D. suzukii reared on apple-based or blueberry-based diets developed more slowly to a smaller adult body size than those on other diets. Cold exposure killed eggs and both first and second instars. Survival of 24 hours at +4 °C by feeding third instars was lowest in blueberry and cherry. Five days at +0.6 °C killed all feeding third instars; this treatment is likely sufficient for targeting D. suzukii in fruit. Two hours at −5 °C or −6 °C killed all wandering third instars and pupae; this exposure could be sufficient for sanitation of packaging.

Structural Differences

Species of the genus Chirothrips Haliday breed and pupate only within grass florets. Each larva is restricted to a single floret, and adult body size is thus presumably related to floret size. Despite this, some Chirothrips species are distinguished only on states that are related to body size. The validity of some commonly recorded members of the C. manicatus species-group, including C. africanus and C. pallidicornis, is therefore considered questionable. Character states that have been used to define the genus Agrostothrips Hood are shown to be variable, and this genus is placed as a new synonym of Chirothrips. An identification key, based on illustrated structural differences, is provided to the Chirothrips known from Iran: C. aculeatus, C. atricorpus, C. kurdistanus, C. manicatus, C. meridionalis and C. molestus.
