Brown flatworm
The rusty flatworm is a dangerous pest that warehouses and food production facilities have to deal with. Its presence can lead to serious losses and food safety hazards. In this article, you will learn how to recognise this insect, what its stages of development are and how to effectively control it to ensure the protection of stored products.
Structure and development of the rusty grain beetle
The rusty grain beetle is a storage pest with a specific structure and development cycle. Its body is 2 to 3.5 mm long, strongly flattened and rusty brown in colour. An important feature of the flat bug is its clearly defined antennae and a series of hairs on its body, which help to identify this insect. Males and females differ in size and the structure of the segments of the abdomen, which makes it easier to recognise the sex in the pest population.
The development cycle of the rusty brown beetle consists of four basic stages: egg, larva, pupa and adult insect. Females lay their eggs directly on food products, and the larvae hatch in optimal conditions after about 1-2 weeks. The larvae go through several stages of moulting and then turn into pupae. After about 2-3 weeks, the pupae emerge as adults, ready to reproduce. The flat bark beetle develops fastest in conditions of high humidity and a temperature of between 25-30°C, which means that suitable storage conditions are crucial in controlling the population of this pest.
Methods of controlling rusty grain beetle
Effective control of rusty flat bugs requires the use of various methods that minimise the risk of serious damage to stored food products. One of the most effective techniques is fumigation, which allows for the elimination of pests at all stages of their life cycle. Fumigation involves the use of special chemicals in the form of gas, which penetrate the insects’ tissues, effectively eliminating them. However, it should be remembered that this process requires proper preparation and strict adherence to safety regulations, which guarantees its high effectiveness in combating rust flatfish.
In addition to fumigation, maintaining high standards of cleanliness and regular disinsection of warehouses is crucial. Regular cleaning, removal of food residues and monitoring of humidity and temperature conditions are steps that significantly reduce the proliferation of rust flatfish. Implementing an integrated approach to pest management, combining fumigation with prevention, not only increases the effectiveness of pest control, but also protects the quality of stored products from contamination and damage.
