It’s interesting that hydroprene (Gentrol) was developed and tested on hemimetabolous insects; Methoprene (Precor) on holometabolous insects (such as beetles). Cockroaches and bed bugs are hemimetabolous, but Gentrol basically had no effect at label dosages on bed bugs even though the early studies said it did. It has always worked well against cockroaches. Methoprene was shown to be efficacious against certain reduviid (Rhodnius) bugs and bed bugs, both hemipterans and both hemimetabolous insects. These particular IGRs are supposed to translocate from original points of application, though I remember hearing another word to explain about their movement in the environment. With respect to two related beetles, the cigarette beetle (Lasioderma serricorne) is supposed to respond to Methoprene and not Hydroprene, while the drugstore beetle (Stegobium paniceum) is supposed to be more responsive to Hydroprene. Other stored product pests also respond to Hydroprene. Insects always surprise us. Lou Louis N. Sorkin, B.C.E.

However, we still need to address our resident populations. My understanding is that Gentrol (hydroprene) will also affect a handful of other common pests, including drugstore beetles. Our biggest concern about using this product is how the IPM coordinator for our campus described how it is used. He made it sound like the chemical travels through the building, or at least parts of it, meaning that it touches everything. We're used to target spraying, but the idea of a chemical floating through the air and coming into contact with photographic collections does raise a concern. Another concern we are curious about is if Gentrol arrests development of larva, do they stay in the larval stage longer and cause more damage to whatever they are feeding on as a result? Mostly I'm interested in hearing if anyone else out there has tried IGRs and what their experiences are.

They work primarily on cockroaches and fleas. They disrupt the molting process of cockroaches and hold fleas in the harmless larval stage. They would not be a good choice for fabric pests or silverfish.

Being as that we are the home to not only a large collection of books and manuscripts, but photographs as well. If we were just a regular library, I'd say to go for it, but we aren't. What is the current thought on using IGRs in cultural institutions, especially those with chemically sensitive collections? Thanks, Alan Van Dyke -- Alan P.
