-The effects of temperature on the development and survival of Ilyocoris cimicoides exclamationis (Scott) were investigated under two photoperiods (15, 18, 20, 22.5, 25, and 28°C under 15L-9D; and 18 and 25°C under 10L-14D). Eggs did not hatch at 15°C and its development was delayed at 28°C. The survival rate of nymphs was significantly lower at 18 and 20°C than those at 22.5, 25, and 28°C. No nymphs reached adults at 18°C under either 15L-9D or 10L-14D. The developmental thresholds for the egg… 
New data on karyotype, spermatogenesis and ovarian trophocyte ploidy in three aquatic bug species of the families Naucoridae, Notonectidae, and Belostomatidae (Nepomorpha, Heteroptera)
TLDR
The scarce data available suggest a tendency for a low level of trophocyte ploidy in the basal infraorders (Nepomorpha and Gerromorpha) and for a high level in the more advanced Pentatomomorha.
