“…The diet made with lyophilized boxwood leaves produced very similar results to those of the diet with fresh leaves; the current results were improved compared with the results of the diets, which also included lyophilized leaves, used by Park () or Kawazu, Nakamura, and Adati (), who reported a longer development time and no pupation, respectively. Moreover, the fungal problems that often occur in the nursery boxes when leaves are used to feed larvae were avoided.…”

Boxwood is a very important component of the natural forests of the eastern Pyrenees. In the low altitudes of these forests, the invasive species Cydalima perspectalis (Walker) causes considerable damage, and there is concern that it will migrate towards the natural forests at higher altitudes. To determine the biological parameters of the local pest population, a semiartificial diet with lyophilized powdered Buxus sempervirens L. leaves was developed. The results obtained indicate that the studied population of C. perspectalis is very similar to the native Japanese population in terms of the number of larval instars to complete development, the development rate and the critical photoperiod for the induction of diapause. It has also been demonstrated that long photoperiods can shorten the duration of larval development. The diapause induction response was classified as type I, and diapause termination was classified as type III. At the two studied temperatures, 25º and 15ºC, the larvae seemed to require a similar number of days in diapause, approximately 3 months, to spontaneously resume development; temperatures can also prompt larvae to resume development. The critical photoperiod in the study area occurs during the second half of August, varying somewhat according to temperature. The greatest defoliation is caused by the offspring of the first generation, while the majority of the larval offspring of the second generation will enter diapause. The survival of natural boxwood in this area will depend on its ability to regrow one or two years after extensive defoliation and on the adaptation of several indigenous natural enemies in the region to feed on C. perspectalis.

“…Similarly, a study testing the larval performance of C. perspectalis larvae reared on an artificial diet containing B. microphylla leaf powder did not show any significant decrease in larval growth or developmental duration on the artificial diet (Kawazu et al. ). These findings suggest a broad acceptance of food plant varieties for larvae of C. perspectalis .…”

Oviposition preference and larval development of the invasive moth Cydalima perspectalis on five European box‐tree varieties

The box‐tree pyralid Cydalima perspectalis (Walker 1859) (Lepidoptera: Pyralidae), native to Eastern Asia, is a newly introduced species causing severe damage to box‐trees (Buxus sp.) in private and public gardens as well as in semi‐natural box‐tree forests in Central Europe. It is so far not known whether different box‐tree subspecies (or varieties) are similarly affected by this invasive moth. In a choice experiment offering branches of five different box‐tree varieties as oviposition sites, we found a preference of female moths for laying their egg clusters on the variety ‘Rotundifolia’, while other varieties were less frequently considered. The preference for ‘Rotundifolia’, the variety with the largest leaves in the tests, remained when intervariety differences in foliar area (mean leaf size × number of leaves) were taken into account. Feeding larvae on leaves of either of the five box‐tree varieties revealed a significant effect of the seasonal generation of C. perspectalis on the growth rate of individuals but no influence of the box‐tree variety. Larvae from the spring generation show the highest growth rate, those from the summer generation a moderate and those from the autumn generation the lowest growth rate. The moths used in the experiments may belong to the 10th to 12th generation present in Europe. The time elapsed since their introduction may be too short for an optimal adaptation to the partly novel diet encountered by the invasive moth.

“…The larval developmental duration, the experienced time from hatch to pupation, influences the health and production of the silkworm (Mo et al 2018). The time of the larval period is affected by temperature, nutrition environmental condition and some other factors (Kawazu et al 2010). In this study, the larval developmental duration of the treatment and control were tested in the same environmental condition.…”

Chinese oak silkworm (Antheraea pernyi) and mulberry silkworm (Bombyx mori) are economically important insects used for silk production and food resource. Entomopathogenic nematodes (EPNs) from the families of Steinernematidae and Heterorhabditidae are beneficial organisms currently considered in biological control. In this paper, we evaluated survival of two silkworm species exposed to four Steinernema species which are widely applied in pest control. The results showed that among four Steinernema species, S. bicornutum and S. feltiae did not have an effect on the larval survival to the two silkworm species, whereas S. carpocapsae and S. glaseri did have an effect. Each Steinernema species poses no threat to hatchability of eggs, pupation rate, larval durations and cocoon shell ratio.
