Seasonal and annual change of a folivorous insect guild in the Siebold's beech forests associated with outbreaks of the beech caterpillar, Quadricalcarifera punctatella (Motschulsky) (Lep.,
TLDR
Seasonal and annual change of folivorous insects of beech associated with outbreaks of the beech caterpillar, Quadricalcarifera punctatella, were investigated in northern Japan from 1988 through 1992 and indicate that delayed induced response of the Siebold beech caused by Q. punctatellA influenced not only the species itself but also other folivory insects.

Estimating the Density of Beech Caterpillar, Quadricalcarifera punctatella, by Frass Drop Samples
TLDR
It was concluded that no compensation was necessary for field application since the decrease was minimal in the field density of the beech caterpillar's last instar larvae from fallen pellets and the density was underestimated when severe defoliation occurred. Expand
Induced response of the Siebold's beech (Fagus crenata Blume) to manual defoliation
TLDR
Siebold's beech (Fagus crenata) was manually defoliated for two successive years and the beech caterpillar was used in a bioassay to determine insect performance. Expand
Insect predation and seasonal seedfall of the Japanese beech, Fagus crenata Blume, in northern Japan
TLDR
Seedfall throughout the season should be investigated in order to fully understand the interaction between seed production and insect infestation. Expand
Influence of rainfall on feeding behavior, growth, and mortality of larvae of the beech caterpillar, Quadricalcarifera punctatella (Motschulsky) (Lep., Notodontidae)
TLDR
Investigation of the direct influence of rainfall on feeding behavior, growth, and mortality of larvae of the beech caterpillar found rainfall in young larval stages resulted in high mortality and a prolongation of the larvalperiod, and rainfall in late larval period curtailed body growth. Expand
An example of numerical response of the carabid beetle, Calosoma maximowiczi Morawitz (Col., Carabidae), to the beech caterpillar, Quadricalcarifera punctatella (Motschulsky) (Lep., Notodontidae)
TLDR
Though carabid larvae are usually scarce in forests, they were abundant the year that catches of adult beetles were heavy, and their abundance showed a strong relationship with the caterpillar density. Expand
Problems in estimating the density of larval beech caterpillar, Quadricalcarifera punctatella (Motschulsky) (Lep., Notodontidae), using frass drops by modification of the Southwood‐Jepson method
TLDR
Three problems were recognized in estimating the last instar larval density of the beech caterpillar, Quadricalcarifera punctatella, using frass drops by modification of the Southwood‐Jepson method; another method was employed which used a cumulative curve of frass falling during outbreak periods and the number of traps necessary decreased with density increase.
