The almond tree, following the olive tree, holds the distinction of being the fruit species occupying the largest area in Morocco, spanning 128,000 ha and hosting 16 million trees. This sector holds immense socio-economic significance both nationally and globally. Despite its prominence, the almond tree faces severe phytosanitary challenges, prominently among them, the False tiger bug of the almond tree, Monosteira unicostata (Mulsant & Rey [Hemiptera: Tingidae]). This polyphagous, sedentary, and gregarious hemipteran, boasting five larval instars and typically generating four generations annually, exhibits a life cycle duration ranging from 2 to 3 months contingent on the season. This pest inflicts notable harm on almond tree leaves by extracting their chlorophyll content through its piercing mouthparts and depositing excrement, impeding respiratory function and adversely impacting fruit development, maturation, and overall production. Diverse control strategies have been implemented to tackle this issue, commencing with prophylaxis involving resistant varieties and sound agricultural practices. Subsequently, biological control methods leveraging natural enemies such as Piocoris luridus and species from families including Coccinellidae, Anthocoridae, Lygaeidae, Miridae, and Nabidae have been employed. Plant-based biopesticides such as azadirachtin (Azadirachta indica), thyme oil (Thymus zygis), Jatropha oil (Jatropha curcas), and concentrated extracts of Artemisia absinthium, as well as mineral-based approaches involving treated kaolin sprays through particle film technology, contribute to the arsenal of control measures. In cases of severe infestations, synthetic active ingredients such as organophosphates, pyrethroids, carbamates, abamectin, and deltamethrin, among others, have proven efficacy in managing this pest.
