204 ELEMENTARY LESSONS ON INSECTS 



Cooperation is the way to success in this course. Let every 

 member of the class do his bit, and the work will go well, and 

 all will benefit by it. Here is a list of the tasks that are 

 common to most of the laboratory exercises: 



1. Collecting of fresh specimens as needed. 



2. Papering or bottling and labelling reserve specimens. 



3. Relaxing of dried, reserve specimens. 



4. Pinning and labelling insects for the collection. 



5. Making slide mounts. 



6. Care of living materials; providing food for nymphs or 

 larvae; providing quarters for pupation; making cages, 

 stocking cages, cleaning cages. 



7. Home problems on crop pests (see p. 173). 



8. Routine. Assembling materials for the laboratory 

 exercise, and putting the stuff away again at its close.
