Hystrichopsyllid fleas
The Hystrichopsyllidae family belongs to the order Siphonaptera. Although these insects are primarily ectoparasites of warm-blooded animals, their presence is relevant in an agronomic context due to their occurrence in agricultural buildings, grain storage facilities, and livestock housing, which can indirectly affect the sanitary conditions of agroecosystems.

Hystrichopsyllid fleas
These insects are not phytophagous and do not feed on plant tissues. However, their high activity in the substrate or dust layers within storage facilities can lead to the transmission of pathogens. The primary damage is related to hygiene violations in agricultural facilities where seeds, forage, and plant-based products are stored.
The biology of Hystrichopsyllidae involves a complex life cycle with complete metamorphosis: egg, larva, pupa, and adult. Adults are characterized by robust spines (ctenidia), which facilitate movement through the host's fur or soil substrate. Larvae feed on organic debris, allowing them to thrive in dust and organic waste accumulated within storage areas.
The harm caused by these pests is linked to the creation of unsanitary conditions. During mass outbreaks, fleas cause significant discomfort to workers and livestock, potentially reducing labor efficiency and animal productivity. Furthermore, their presence in grain storage areas mandates immediate sanitation and pest control measures.
Control measures are focused on strict adherence to sanitary and hygienic standards. It is recommended to perform regular wet cleaning combined with insecticide applications to floors and crevices. It is essential to eliminate rodent access to storage sites, as rodents serve as the primary hosts and carriers for the members of this family.
