The effect of population density and other factors on the number of offspring of Myelophilus piniperda


, : The effect of population density and other factors on the number of offspring of Myelophilus piniperda. Ann. ent. fenn., Helsinki. 34: 3, 135-48

A team study carried out simultaneously in Denmark, Finland, Norway and Sweden from 1961 to 1967 on Pine bolts in breeding cages. At population densities of up to ca. 200 females/sq.m. of surface, the number of galleries increased proportionately with number of females, and this density produced the highest number of young beetles.

Polymer lattice density functional theory (PLDFT) is used to investigate the cononsolvency (CNS) phenomena related to polymer adsorption in a slit pore. Specifically, the two simplest types of CNS are examined: CNS1 with solvent-cosolvent binding...
