Research Objective

To present a comprehensive checklist of bugs (Hemiptera) associated with agroecosystems in the north-west region of Morocco, identifying species, their distribution, and ecological roles.

Methodology

Field surveys were conducted between spring and summer of 2019 and 2020 in three crop fields (cereal, broad bean, and alfalfa) in Sidi Kacem, northwest Morocco. Two sampling techniques were employed: mowing net and sight hunting. Species identification was based on external morphological characteristics using a binocular magnifier and reference keys.

Discussion

The study contributes to understanding the insect fauna in Morocco, particularly Hemiptera in agroecosystems. Pentatomidae and Scutelleridae families were noted as significant agricultural pests. Predatory species like Rhynocoris erythropus and Peirates stridulus were identified as beneficial for biological control. The findings highlight the need for further research into control strategies and sustainable pest management.

Key Findings

A total of 6 families of Hemiptera were identified: Reduviidae, Lygaeidae, Pentatomidae, Cercopidae, Scutelleridae, and Alydidae. Ten species were documented: Peirates stridulus, Rhynocoris erythropus, Camptopus lateralis, Lygaeus equestris, Piezodorus lituratus, Dolycoris numidicus, Carpocoris fuscispinus, Aelia acuminata, Eurygaster austriaca, and Cercopis intermedia. Palaearctic chorotype species constituted 50% of the recorded species.

Conclusion

This research provides a valuable inventory of Hemipteran species in northwest Moroccan agroecosystems, contributing to faunistics and distribution knowledge. It emphasizes the importance of understanding pest ecology for developing targeted and effective control measures, paving the way for sustainable pest management practices.
