In 2004, an invasive planthopper species erroneously identified as Peregrinus maidis (Ashmead) devastated cornfields in Region 9 [Western Mindanao], 10 [Northern Mindanao], 11 [Southern Mindanao], 12 [Central Mindanao] and the Autonomous Region of Muslim Mindanao [Philippines]. Diagnostic works at Plant Quarantine Support Laboratory of the National Crop Protection Center-Crop Protection Cluster, UP Los Baños and the Crop Protection Division, Bureau of Plant Industry, showed not a single Peregrinus maidis (Ashmead) from collections in Sultan Kudarat and South Cotabato. The planthopper was initially placed under the Sogatella genus based on genitalia features. Recent identification with the help of experts from Australia and Britain showed that it is Stenocranus pacificus Kirkaldy. Stunted plants and blackened leaves due to sooty molds are the signs of attack. Later, hopper burn becomes evident on the leaves. Young corn ears fail to reach grain filling stage due to fermentation brought about by honeydew secretions. As of 2006, this pest has reached Laguna, Aurora, Pangasinan, Isabela and Cagayan. By 2009, it is reported in Occidental Mindoro, La Union, Ifugao. More corn growing areas in Luzon are now threatened. Implementation of a cooperative community-based surveillance and management program is now imperative to prevent the potential damages and spreading menace of this invasive alien pest in other corn-growing areas.
