The seasonality, relationship of temperature and
photoperiod to growth and post-diapause development, and
overwintering behavior of codling moth, Cydia pomonella L.,
(Lepidoptera: Olethreutidae) were studied over a three year
(1986-1989) period. The developmental threshold varied from
a low of 9.66°C for the second instar to a high of 14.23°C
for...

To assess the effect of summer moisture stress on the capacity of tansy ragwort (Senecio jacobaea L.) to compensate for defoliation by the cinnabar moth (Tyria jacobaeae LT7), the performance of plants grown under different irrigation regimes was measured. The proportion of plants producing
new leaves following defoliation, the number...
The cinnabar moth (Tyria jacobaeae (L.), Lepidoptera: Arctiidae) is an icon in
population ecology and biological control that has recently lost its shine based on evidence
that (1) it is less effective than alternatives (such as the ragwort flea beetle Longitarsus
jacobaeae (Waterhouse) (Coleoptera: Chrysomelidae) for controlling ragwort Senecio
jacobaea...
