Artrópodos asociados a la inflorescencia de ginger rojo (Alpinia purpurata (VIEILL.) K. SCHUM.) en plantaciones de Tabasco, México

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.Objetivo: Identificar los artrópodos que se asocian a la inflorescencia de Alpinia purpurata en plantaciones comerciales del estado de Tabasco, así como determinar la fluctuación poblacional de los más abundantes. Diseño/metodología/aproximación: Se realizaron muestreos quincenales durante 12 meses en tres plantaciones localizadas en los municipios de Comalcalco, Centro y Teapa. Resultados: Se obtuvieron 22,911 especímenes de artrópodos pertenecientes a las clases Insecta, Arachnida, Malacostraca y Diplopoda. Los insectos constituyeron el grupo más numeroso (96.8%), el cual estuvo representado básicamente por hormigas (Hymenoptera: Formicidae), pulgones (Hemiptera: Aphididae) y piojos harinosos (Hemiptera: Pseudococcidae), que en conjunto constituyeron el 94.7% del total de artrópodos. La fluctuación poblacional de estos insectos fue relativamente diferente en cada plantación, pero permanecieron en las inflorescencias durante los 12 meses de estudio. Limitaciones/implicaciones: Debido a que la cantidad de artrópodos recolectados fue considerablemente alta, no fue posible identificar los especímenes a niveles taxonómicos inferiores a los que aquí se reportan. Hallazgos/conclusiones: Las hormigas, pulgones y piojos harinosos fueron los artrópodos más abundantes, y se presentaron todo el año. Debido a que infestan las inflorescencias, se consideran plagas del cultivo de ginger en el estado de Tabasco. Estos insectos son plagas del ginger en otros países productores, y comúnmente son la causa de rechazo del producto destinado a la exportación

Record of damage by Aulacoscelis melanocera (Coleoptera: Orsodacnidae) on Cycas revoluta (Cycadaceae) in Campeche, Mexico.

On May 7, 2018, in the garden of an archaeological site in northern Campeche, Mexico, a Cycas revoluta plant was observed with approximately 40 % of the foliage damaged by a swarm of Aulacoscelis melanocera (Coleoptera: Orsodacnidae). The present work constitutes the first report of this species causing severe damage in C. revoluta and the first record of this insect for the state of Campeche

Phytophagous invertebrates that damage orchids in gardens of western Tabasco, Mexico

Objective: To record six species of invertebrates that damage orchids in gardens in western Statae of Tabasco, Mexico. Methodology: As part of the project "Fauna associated with cultivated plants in the south-southeast region of Mexico", non-systematic collects of invertebrates were made that were observed damaging orchids in three gardens in the western part of the state of Tabasco. The invertebrates were identified through descriptions and taxonomic keys. Results: Four species of insects of the order Coleoptera and two species of molluscs of the class Gastropoda are recorded. The insects are (1) Diabrotica adelpha Harold (Chrysomelidae), (2) Stethobaris sp. (Curculionidae), (3) Cyclocephala guttata Bates (Scarabaeidae), these three damaging flowers of Brassavola nodosa (L.) Lindley, and (4) Stethobaroides nudiventris Champion (Curculionidae) damaging flowers of Catasetum integerrimum Hook. The molluscs are (1) Subulina octona (Bruguière) (Subulinidae) scraping leaves of Gongora leucochila Lem., Phalaenopsis sp. and C. integerrimum, and (2) Sarasinula plebeia(P.Fischer) (Veronicellidae) damaging leaves of C. integerrimum. Limitations on study: It was not possible to specifically identify one of the insect species (Stethobaris sp.) and one of the damaged orchid species (Phalaenopsis sp). Conclusions: This work contributes to the knowledge of invertebrates that damage orchids in Mexico, and is a basis for future studies to determine the incidence and importance of these organisms in the conservation and cultivation of orchids in this area of ​​Tabasco.Objective: To record six species of invertebrates that damage orchids in gardens in the western area of the state of Tabasco, Mexico.

Avifauna associated to a home garden in Valladolid, Yucatan, Mexico

Objective: Identify the birds associated with a family garden in Valladolid, Yucatan, Mexico and know which ones use cultivated plants as a food resource. Methodology: As part of the project “Fauna associated with cultivated plants in the south-southeast region of Mexico”, 36 field trips were carried out, six hours per day (6:00 – 10:00 and 16:00-18:00) in the period from March 2022 to April 2023, in a home garden in Valladolid, Yucatan, Mexico. The birds were observed with binoculars, photographed with digital cameras and identified with field guides. Results: We observed 67 species of birds belonging to 14 orders and 28 families. Of these species, 14 are migratory, 3 endemics and 4 subject to special protection in Mexico. Additionally, we recorded 21 species of birds feeding on 22 species of cultivated plants. The plant resource most used by birds were fruits (16), followed by nectar (5) and young leaves (1). The plant species most consumed by birds were Manilkara zapota L., Carica papaya L. and Spondias purpurea L., which were used by 3 species of birds each. The bird that consumed the most cultivated plants was the Melanerpes aurifrons Wagler, which fed on 5 species. Study limitations: It was not possible to specifically identify two species of birds: Contopus sp. and Myarchus sp. Conclusions: This study contributes to the knowledge of birds associated with home gardens in Valladolid, Yucatan and constitutes a basis for future studies on bird-plant trophic interactions in Mexico.Objective: To identify the birds associated to a home garden in Valladolid, Yucatan, Mexico, and to understand which ones use cultivated plants as food.Methodology: As part of the project “Fauna associated to cultivated plants in the south-southeast region of Mexico”, 36 field visits were carried out, for six hours per day (6:00-10:00 and 16:00-18:00 hrs.), in the period from March 2022 to April 2023, in a home garden in Valladolid, Yucatan. The birds were watched with binoculars, photographed with digital cameras, and identified with field guides.Results: A total of 67 bird species were observed, which belonged to 14 orders and 28 families. Of the species, 14 are migratory, three endemic, and four subject to special protection in Mexico. In addition, 21 bird species were found feeding off 22 species of cultivated plants. The most frequently used plant resource by the birds were fruits (16), followed by nectar (5) and tender leaves (1). The most consumed plants species by the birds were Manilkara zapota (L.) P. Royen, Carica papaya L. and Spondias purpurea L., which were used by three bird species each. The bird that consumed more cultivated plants was the Golden-fronted Woodpecker (Melanerpesaurifrons Wagler) that fed off five species.Limitations on study: It was not possible to identify two birds at the species level: Contopus sp. and Myiarchus sp.Conclusions: This study contributes to the knowledge of birds associated to home  gardens and constitutes the basis for future studies on bird-plant trophic interactions in Mexico
