Thank you, Pat, that is very helpful advice, which we will implement! Cheers,

The fact that other adult females will be present does not play a substantial role in whether or not adult males will go to the traps containing those pheromones. Males will continue to search for pheromone even after successfully mating with a female, so as long as the pheromone traps are within range of the males picking up the pheromone with their antennae, they will go to the traps and be captured. In temperate zones of cold winters and warm summers, the adults do not emerge until early spring. Thus, monitoring in these environments does not make sense during the cold winter months. In tropical zones, the adults are active year-round and thus can be monitored year-round. When monitoring indoor storage or exhibit spaces, consider using a dermestid food attractant lure in a pitfall trap rather than a sex pheromone. You can monitor all year-round in any climate zone with these. Carpet beetles spend 80% of their lives in the less-mobile larval stage. If you pick up larvae in your monitors, then you know that an infestation is located nearby. Adult beetles, both male and female, have been observed going to the food attractant baits as well. Another thing to consider when speaking about these insect pests is that both varied and black carpet beetles actively feed on the pollen in flowering plants as adults. In many areas, large numbers of adults can be found on outdoor flowers at certain times of the year and this is where much of the mating activity occurs. While a heavy presence of adults outdoors does not necessarily translate into indoor infestations, it does put more pest pressure on those structures in close proximity. Positioning beds of flowering bushes and plants away from museums or historic houses, lessens that pressure to some degree.

It is my understanding that pheromone traps don’t work that well when the adults are flying, because there are lots of real females around – but aren’t they only flying for a few months (in the spring/summer) of the year anyway? Clarification of this would be really helpful! Cheers, Tonya -- You received this message because you are subscribed to the Google Groups "Museumpests" group.
