Arthropods associated with the inflorescence of the red ginger (Alpinia purpurata (VIEILL.) K. SCHUM.) in plantations of Tabasco, Mexico

Abstract

Objective: To identify the arthropods that are associated with the inflorescence of Alpinia purpurata in commercial plantations of the state of Tabasco, Mexico, as well as to determine the population fluctuation of the most abundant arthropods.

Design/methodology/approach: Biweekly samplings were carried out during 12 months in three plantations located in Comalcalco, Centro and Teapa municipalities.

Results: 22,911 specimens of arthropods belonging to the classes Insecta, Arachnida, Malacostraca and Diplopoda were obtained. The insects constituted the most numerous group (96.8%), which was represented basically by ants (Hymenoptera: Formicidae), aphids (Hemiptera: Aphididae) and mealybugs (Hemiptera: Pseudococcidae), constituting 94.7% of the total arthropods. The population fluctuation of these insects was relatively different in one plantation with respect to the others, but they remained in the inflorescences during the 12 months of study.

Limitations/implications: Because the quantity of arthropods collected was considerably high, it was not possible to determine the specimens at taxonomic levels lower than those reported here.

Findings/conclusions: The ants, aphids and mealybugs were the most abundant arthropods, and they were present throughout the year. Because they infest the inflorescences, they are considered pests of the ginger crop in the state of Tabasco. These insects are pests of ginger in other producing countries, and they are commonly the cause of rejection of the product destined for export.
