Forestgeo Arthropod Initiative Annual Report 2018
FORESTGEO ARTHROPOD INITIATIVE ANNUAL REPORT 2018 Program coordinator: Yves Basset, Smithsonian Tropical Research Institute (STRI), [email protected] I. BACKGROUND AND PARTICIPATING FORESTGEO SITES The ‘Arthropod Initiative’ of the Center for Tropical Forest Science (CTFS) aims at monitoring key arthropod assemblages over long-term and studying insect-plant interactions over the network of the Forest Global Earth Observatories (ForestGEO, https://forestgeo.si.edu/research-programs/arthropod-initiative). The Initiative integrates with ongoing monitoring of plant dynamics within the ForestGEO network, causes minimum possible impact to the plots and focus on a priority set of assemblages chosen for their ecological relevance, taxonomic tractability and ease of sampling. At each participating ForestGEO site, the first years of the program are usually devoted to a ‘baseline’ survey. The baseline survey is followed by longer-term programs of field work and analysis, organized into two main sub-programs: monitoring, and key interaction studies. The monitoring sub-program is directed to detecting long-term changes, as reflected in priority assemblages, driven by climatic cycles, climatic change and landscape scale habitat alteration. Monitoring protocols are derived from those used during the baseline survey. The food web approach of interaction studies targets interactions between plants and specific insect assemblages, with different protocols than those used for monitoring. So far, the Arthropod Initiative involves nine ForestGEO sites: Yasuni in Ecuador, Barro Colorado Island (BCI) in Panama, Rabi in Gabon, Khao Chong (KHC) in Thailand, Tai Po Kau (Hong Kong), Dinghushan and Xishuangbanna (XTBG) in China, Bukit Timah in Singapore and Wanang (WAN) in Papua New Guinea. At BCI, four full-time research assistants were in charge of arthropod monitoring protocols in 2018: Filonila Perez, Ricardo Bobadilla, Yacksecari Lopez and Alejandro Ramirez. -

They form a complex consisting of many species belonging to several genera that affect the roots of commercial crops. The objec- tive of the present study was to identify the members of the complex present in two localities (Caldono and Buenos Aires) and collect basic information on their biology, economic impor- tance, and larval morphology. The first of two types of sampling involved sampling adults in light traps installed weekly throughout one year. The second method involved larval collec- tions in plots of cassava, pasture, coffee, and woodland. Each locality was visited once per month and 10 samples per plot were collected on each occasion, with each sample from a quad- rants 1 m2 by 15 cm deep, during 1999-2000. Light traps collected 12,512 adults belonging to 45 species and 21 genera of Scarabaeidae within the subfamilies Dynastinae, Melolonthinae, and Rutelinae. Members of the subfamily Dynastinae predominated with 48% of the species (mostly Cyclocephala), followed in decreasing order by Melolonthinae (35%) and Rutelinae (15%, principally Anomala). -

Quick Guide for the Identification of Maryland Scarabaeoidea Mallory Hagadorn Dr. Dana L. Price Department of Biological Sciences Salisbury University This document is a pictorial reference of Maryland Scarabaeoidea genera (and sometimes species) that was created to expedite the identification of Maryland Scarabs. Our current understanding of Maryland Scarabs comes from “An Annotated Checklist of the Scarabaeoidea (Coleoptera) of Maryland” (Staines 1984). Staines reported 266 species and subspecies using literature and review of several Maryland Museums. Dr. Price and her research students are currently conducting a bioinventory of Maryland Scarabs that will be used to create a “Taxonomic Guide to the Scarabaeoidea of Maryland”. This will include dichotomous keys to family and species based on historical reports and collections from all 23 counties in Maryland. This document should be cited as: Hagadorn, M.A. and D.L.

Their larvae (white grubs) are below-ground pests of turfgrass, corn, and other agricultural crops. In some regions, such as the Midwestern United States, they are among the most important pest of turfgrass, building up in high densities and consuming roots below the soil/thatch interface. Five species are known to be important pests of turfgrass in North America, including northern masked chafer, Cyclocephala borealis Arrow; southern masked chafer, Cyclocephala lurida Bland [for- http://jipm.oxfordjournals.org/ merly Cyclocephala immaculata (Olivier)]; Cyclocephala pasadenae (Casey); Cyclocephala hirta LeConte; and Cyclocephala parallela Casey. Here we discuss their life history, ecology, and management. Key words: Turfgrass IPM, white grub, Cyclocephala, masked chafer Many species of scarabs are pests of turfgrass in the larval stage southern Ohio, and Maryland. The two species have overlapping (Table 1). Also known as white grubs, larvae of these species feed distributions throughout the Midwest, particularly in the central on grass roots and damage cultivated turfgrasses. -

Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4. -
Report of Astaena Pygidialis Kirsch (Coleoptera: Scarabaeidae)
Report of Astaena pygidialis Kirsch (Coleoptera: Scarabaeidae), the main chafer beetle causing damage to avocado fruit and young leaves in Antioquia Department, Colombia Claudia M. Holguin1,*, and Rosa H. Mira1 Abstract Scarab beetles (Coleoptera: Scarabaeidae) are one of the most limiting pests of avocado in Antioquia Department, Colombia. The establishment of management strategies to control these beetles has been difficult because the species causing damage to avocado fruit and young leaves have not been identified. Selected commercial avocado fields were surveyed at different times of d for scarab beetle adults affecting small fruit and young leaves, as well as other plant structures such as flowers, tender buds, stems, and mature leaves. Additionally, ultraviolet light traps were placed at each field to quantify the species captured. After direct scouting of avocado trees, the only scarab beetle species detected causing damage to fruit and young leaves at all sampling sites was Astaena pygidialis Kirsch (Coleoptera: Melolonthinae). Adults were observed chewing the green skin of small fruit causing striations on the fruit and skeletonization of young leaves by chewing the leaf tissue between veins on the upper surface. Other species observed include Anomala cincta Say (Coleoptera: Rutelinae), Charioderma xylina Blanchard, and Strigoderma sp. (all Coleoptera: Rutelinae) associated with flowers, Isonychus sp. (Coleoptera: Melolonthinae) with flower buds, Cyclocephala fulgurata Burmeister (Coleoptera: Dynastinae) with tender buds, stems and flowers, andAstaena valida Burmeister and Plectris pavida (Burmeister) (both Coleoptera: Melolonthinae) with mature leaves. The species detected through scouting also were captured with light traps. The dominant species captured with light traps was Phyllophaga obsoleta (Blanchard) (Coleoptera: Melolonthinae), which was not observed causing damage to avocado fruit or young leaves. -
