Report of the State Entomologist of Connecticut for the year .. . Figure 8. Result of mouse damage. Photographed second year after girdhng. It is planned to repeat the work. Investigation of the drift of mice (2) was undertaken near Guilford,Conn., in an old unused pasture, adjacent to an orchard, where mousepopulations are very high. An area has been cleaned of mice by area has been surrounded by a barrier of traps to catch any mice Rodent Control 95 drifting into it. The trap sites are numbered and marked. The trap lineis_rmi at intervals during the month and all data recorded.


Report of the State Entomologist of Connecticut for the year .. . Figure 8. Result of mouse damage. Photographed second year after girdhng. It is planned to repeat the work. Investigation of the drift of mice (2) was undertaken near Guilford,Conn., in an old unused pasture, adjacent to an orchard, where mousepopulations are very high. An area has been cleaned of mice by area has been surrounded by a barrier of traps to catch any mice Rodent Control 95 drifting into it. The trap sites are numbered and marked. The trap lineis_rmi at intervals during the month and all data recorded. It is planned to run the test for a year to get a complete picture ofthe drift and reinfestation rates. Data collected will include: Date and time traps are set and re-run;weight, sex, measurements of all species caught; type of cover; weatherconditions; map of area; when heaviest drift occurs; why it occurs;sex drifting most; size of individuals drifting; Figure 9. Apple tree girdled hy meadow mice,consecutive years damage. Note This study was set up December 17, 1938, and so has not been underway long enough to draw any conclusions. A progress report has beenmade to the Control Methods Research Laboratory and to the ExperimentStation. The mvestigation of the food habits of pine mice (3) has been startedonly recently. Thirty stomachs will be taken from pine mice caught inthe field each month and sent to the Food Habits Research Laboratories 96 Connecticut Experiment Station Bulletin 428 of the Bureau of Biological Survey in Washington. Chewing habits of themice make it difficult to determine stomach contents without check mate-rials and use of a microscope. Therefore the stomachs will be analyzedwith the aid of an index and herbarium collection being set up at the presenttime. The index will consist of stomachs taken from one or two mice fedon a single food material under caged conditions. The food will be takenfrom the orchard floors
