Applied Entomology

Collection, identification and mode of damage of insect pests of various crops, Fruits Vegetables, Stored grains and household Insecticide formulations, their dilutions and safe handling Use of application equipment, instructions for apiculture, sericulture and lac-culture Field visits for collection of different developmental stages of insects belonging to different orders

Basic collecting can be done by simply catching insects with your hands or a net and putting them into some type of jar. But, for more serious collecting, additional equipment is needed. Collecting supplies are somewhat dependent on the groups of insects being searched for and the time of day they are collected. Supplies needed for day collecting can be quite different than those used for night collecting. The same idea applies to collecting terrestrial insects versus aquatic insects, or flying insects versus soil dwelling insects. Indeed, it is difficult, if not impossible to collect all types of insects by an individual on a single collecting outing. It would also be impractical to carry the many supplies for all collecting methods by a single person. Many collectors only collect those insects in groups they work with, so they can handle the material collected in an efficient manner. In our museum, we collect a wide variety of insects using many different methods and traps. I have given a list of many of the collecting supplies and traps used by museum personnel and students below. There are additional traps and supplies, and different methods used by other collectors around the world, but this should serve as a starting point anyway. There is some overlap between supplies used for both day and night collecting; therefore those supplies are included in the same list below. Supplies for collecting aquatic insects are given after the list of terrestrial insect collecting supplies. Following the collecting supply lists, a list of different types of traps used for the collection of insects is given. Some of the supplies are more basic than others, if not necessary; however, the individual can best decide what is most useful to her or him. Not everything below is linked to a page, because it is fairly obvious what some of the supplies are for.

Collecting supplies for Terrestrial Insects

1. Collecting bag or other container
2. Insect nets
3. Collecting jars (killing jars/alcohol vials)
4. Envelopes
5. Forceps
6. Beat sheet
7. Aspirator
8. Sifter/pan (for leaf litter)
9. Bait
10. Hatchet, knife, small garden shovel or other tools
11. Permanent ink pen and label paper
12. Log book
13. GPS unit/maps
14. Camera (digital or film)
15. Sunscreen
16. Repellant

Methods of Insect Collection

• Berlese funnels. These are devices to drive insects and other arthropods out of samples of leaf litter.
• Hand netting.
• Light traps.
• Yellow pan traps.
• Pitfall traps
• Malaise traps
• Flight interception traps (also called Barrier traps)
• Lindgren funnel traps
• Bait traps (various types)
• Japanese beetle traps
• Blacklight traps
• Pan traps

1. Collecting equipment Regardless of the type of insects being sought all collectors should have a good collecting bag.
2. A photographic accessory bag with a flat, rigid bottom and a variety of compartments is ideal. However, some entomologists use fishing jackets. Six meter wide malaise traps at Keep River.
