Insect of the Month: Common Silverfish (Lepisma saccharina)

Silverfish and firebrats are placed in the order Thysanura which is considered one of the most primitive of the living insect orders.

There are four species considered common in North America; the Firebrat (Thermobia domestica), the Common Silverfish (Lepisma saccharina), the Gray or Longtailed Silverfish (Ctenolepisma longicaudata), and the Four-Lined Silverfish (Ctenolepisma quadriseriata).

Clothes Moth Management

Webbing clothes moths belong to the family Tineidae which contains over 3,000 species and is collectively known as the clothes moth or fungus moth family. Many moth species in the Tineidae family look very similar to one another. In many cases, proper identification requires dissection of the abdomen to view the genitalia structure to determine the exact species.

Watch: Black Carpet Beetle Life and Feeding Habits

Black carpet beetles can be a serious pest of wool carpets and rugs but can also be a pest of dried food goods. Pheromone monitors can assist in locating the feeding sources of this pest so control can be achieved. Keys to identifying the larvae and adults as well as an explanation of their life history and feeding habits are covered in this video by entomologist Patrick Kelley.

Black Carpet Beetle, Attagenus unicolor: A Pest of Carpets and Dried Food

When the common name of an insect includes what it likes to eat, (think clothes moths, flour beetles, saw-toothed grain beetles, etc.) you know that those items are particularly at risk of being eaten by that specific species. While carpets made from wool are a fond food source for black carpet beetle larvae, carpets are only one menu item in a long list of potential foods for this pest. Somewhat surprising to many is that black carpet beetles are a common pest on grain-based, dried food goods.

The Red-Legged Ham Beetle, No friend of hams, and even worse friend of pet food

Red-legged ham beetle (RLHB for short) is about a quarter of an inch long, and has iridescent green wings, and dark orange legs. The adults of these insects are quick on their feet as well as very capable fliers. Effective flight is a necessity when scouting out ephemeral food sources like dead animals. What’s more, these insects are also good competitors of other insect larvae.

Insect of the Month: Fruit Fly (Drosophila melanogaster)

Fruit flies feed primarily on moist, decaying, organic food items including fruits, vegetables and other fermenting liquids.

Fruit fly infestations can be identified by numerous adult insects flying around a food source or from the maggots infesting decaying food. In heavy fruit fly infestations, pupae can be found some distance from the food source when the larvae migrate away to find a dry, dark, and safe place to pupate.

Stored Product Pests in the Food Distribution/Food Warehouse Setting

While a lot of focus is given to pest prevention and control in the production world, I want to move on down the chain of custody to warehousing and distribution. There are a multitude of ways stored product pests and their issues arise in this setting. Warehouses are high volume, high traffic hubs for products that come from all over the world. They can house a vast variety of items. This makes an integrated pest management system very complex and involved.
