A Review of Sampling and Monitoring Methods for Beneficial Arthropods
insects Review A Review of Sampling and Monitoring Methods for Beneficial Arthropods in Agroecosystems Kenneth W. McCravy Department of Biological Sciences, Western Illinois University, 1 University Circle, Macomb, IL 61455, USA; [email protected]; Tel.: +1-309-298-2160 Received: 12 September 2018; Accepted: 19 November 2018; Published: 23 November 2018 Abstract: Beneficial arthropods provide many important ecosystem services. In agroecosystems, pollination and control of crop pests provide benefits worth billions of dollars annually. Effective sampling and monitoring of these beneficial arthropods is essential for ensuring their short- and long-term viability and effectiveness. There are numerous methods available for sampling beneficial arthropods in a variety of habitats, and these methods can vary in efficiency and effectiveness. In this paper I review active and passive sampling methods for non-Apis bees and arthropod natural enemies of agricultural pests, including methods for sampling flying insects, arthropods on vegetation and in soil and litter environments, and estimation of predation and parasitism rates. Sample sizes, lethal sampling, and the potential usefulness of bycatch are also discussed. Keywords: sampling methodology; bee monitoring; beneficial arthropods; natural enemy monitoring; vane traps; Malaise traps; bowl traps; pitfall traps; insect netting; epigeic arthropod sampling 1. Introduction To sustainably use the Earth’s resources for our benefit, it is essential that we understand the ecology of human-altered systems and the organisms that inhabit them. Agroecosystems include agricultural activities plus living and nonliving components that interact with these activities in a variety of ways. Beneficial arthropods, such as pollinators of crops and natural enemies of arthropod pests and weeds, play important roles in the economic and ecological success of agroecosystems. -
Iconic Bees: 12 Reports on UK Bee Species
Iconic Bees: 12 reports on UK bee species Bees are vital to the ecology of the UK and provide significant social and economic benefits through crop pollination and maintaining the character of the landscape. Recent years have seen substantial declines in many species of bees within the UK. This report takes a closer look at how 12 ‘iconic’ bee species are faring in each English region, as well as Wales, Northern Ireland and Scotland. Authors Rebecca L. Evans and Simon G. Potts, University of Reading.

The most pervasive causes of bee species decline are to be found in the way our countryside has changed in the past 60 years. Intensification of grazing regimes, an increase in pesticide use, loss of biodiverse field margins and hedgerows, the trend towards sterile monoculture, insensitive development and the sprawl of towns and cities are the main factors in this. I agree with the need for a comprehensive Bee Action Plan led by the UK Government in order to counteract these causes of decline, as called for by Friends of the Earth. -

In this biome, bees perform the most frequent pollination system. Over the last decade, network analysis has been extensively applied to the study of plant–pollinator interactions, as it provides a consistent view of the structure of plant–pollinator interactions. The aim of this study was to use palynological studies to obtain an understanding of the relationship between floral visitor bees and the pioneer plant S. didymum in a fragment of the Atlantic Forest, and also learn about the other plants that interact to form this network. Five hundred bees were collected from 32 species distributed into five families: Andrenidae, Apidae, Colletidae, Megachilidae, and Halictidae. The interaction network consisted of 21 bee species and 35 pollen types. -
Food Load Manipulation Ability Shapes Flight Morphology in Females Of
Polidori et al. Frontiers in Zoology 2013, 10:36 http://www.frontiersinzoology.com/content/10/1/36 RESEARCH Open Access Food load manipulation ability shapes flight morphology in females of central-place foraging Hymenoptera Carlo Polidori1*, Angelica Crottini2, Lidia Della Venezia3,5, Jesús Selfa4, Nicola Saino5 and Diego Rubolini5 Abstract Background: Ecological constraints related to foraging are expected to affect the evolution of morphological traits relevant to food capture, manipulation and transport. Females of central-place foraging Hymenoptera vary in their food load manipulation ability. Bees and social wasps modulate the amount of food taken per foraging trip (in terms of e.g. number of pollen grains or parts of prey), while solitary wasps carry exclusively entire prey items. We hypothesized that the foraging constraints acting on females of the latter species, imposed by the upper limit to the load size they are able to transport in flight, should promote the evolution of a greater load-lifting capacity and manoeuvrability, specifically in terms of greater flight muscle to body mass ratio and lower wing loading. Results: Our comparative study of 28 species confirms that, accounting for shared ancestry, female flight muscle ratio was significantly higher and wing loading lower in species taking entire prey compared to those that are able to modulate load size. Body mass had no effect on flight muscle ratio, though it strongly and negatively co-varied with wing loading. Across species, flight muscle ratio and wing loading were negatively correlated, suggesting coevolution of these traits. Conclusions: Natural selection has led to the coevolution of resource load manipulation ability and morphological traits affecting flying ability with additional loads in females of central-place foraging Hymenoptera. -

First Observations on Nesting and Immatures of the Bee Genus Ancyla (Apoidea: Apidae: Apinae: Ancylaini)
AMERICAN MUSEUM NOVITATES Number 3749, 24 pp. June 25, 2012 First Observations on Nesting and Immatures of the Bee Genus Ancyla (Apoidea: Apidae: Apinae: Ancylaini) JAKUB STRAKA1 AND JEROME G. RoZEN, JR.2 ABSTRACT Herein we present information on the nest architecture and nesting biology primarily of Ancyla asiatica Friese and, to a lesser extent, of A. anatolica Warncke, both found near Adana, Turkey. These two ground-nesting species visit Apiaceae for mating and larval provisions, with A. asiatica going to Daucus carota and A. anatolica, to Eryngium. The cocoon of A. asiatica is described in detail as are the mature oocytes of both species and the pre- and postdefecating larvae of A. asiatica. Each site was attacked by a separate, unnamed cleptoparasitic species of Ammobates (Nomadinae). The relationships of the Ancylaini to other apine tribes are discussed based on their mature larvae, and a revised tribal key to mature larvae of nonparasitic, noncor- biculate Apinae is presented. INTRODUCTION Of all tribes of nonparasitic Apidae, the natural history of the Ancylaini3 has been the least investigated. Until now, nothing has been recorded concerning the nests of any species, 1 Department of Zoology, Faculty of Science, Charles University in Prague, CZ-12844 Prague 2, Czech Republic. 2 Division of Invertebrate Zoology, American Museum of Natural History. 3 The spelling of tribe Ancylini Michener, 1944, has recently been emended to Ancylaini to remove hom- onymy with Ancylini Rafinsque, 1815 (Mollusca, Gastropoda) (Engel et al., 2010: ICZN Ruling (Opinion 2246-Case 3461).

Neff Central Texas Melittological Institute, 7307 Running Rope, Austin, Texas 78731, USA Received 13 June 2007 – Revised 28 September 2007 – Accepted 1 October 2007 Abstract – The components of nest provisioning behavior (resources per cell, transport capacity, trip dura- tion, trips per cell) are examined for a data set derived from the literature and various unpublished studies. While there is a trade-off between transport capacity and trips required per cell, the highest provisioning rates are achieved by bees carrying very large pollen loads at intermediate trip durations. Most solitary bees appear to be either egg or resource limited, so sustained provisioning rates over one cell per day are unusual.

In our paper (LAROCA, REYNAUD DOS SANTOS & SCHWARTZ FILHO, 1993) in which we studied several life history aspects of this species, we used the old name of this species, Melanocentris dorsata. Among several aspects, we postulated that Ptilotopus and Melanocentris together are a monophylectic group, Ptilotopus being a Melacentris-derived group (called by us in that occasion as Melanocentris). Our suspecion was based on morphological similarities amoung the groups and in the fact 1 Professor Sênior do setor de Ciências Biológica da Universidade Federal do Paraná (Curitiba, PR).

Centris is a relatively diversified genus of medium to large bees. In neotropical sites they are quiet common in the Brazilian “cerrado” (a type of savanna) and other open vegetations as well as in forest habitats.
