A Visual Guide for the Identification of British Coelioxys Bees
1 Introduction The Hymenoptera is an order of insects that includes bees, wasps, ants, ichneumons, sawflies, gall wasps and their relatives. The bees (family Apidae) can be recognised as such by the presence of feather-like hairs on their bodies, particularly near the wing bases. The genus Coelioxys Latreille belongs to the bee subfamily Megachilinae. There are six species of Coelioxys present in mainland Britain. Two other species are found in Guernsey but not mentioned in this pictorial key (C. afra Lepeletier and C. brevis Eversmann). Natural History Coelioxys (their various English names are: Sharp-tailed Bees, Sharp-abdomen Bees and Sharp-bellied Bees) are among those known as cuckoo bees because the larvae grow up on food stolen from Leaf-cutter Bees (Megachile Latreille) or Flower Bees (Anthophora Latreille). The genus Megachile probably includes the closest relatives of Coelioxys. Female Megachile construct nests of larval cells from leaves and provision each cell with a mixture of pollen and nectar for the young. A female Coelioxys will seek these out and apparently uses its sharp abdomen to pierce the cells. An egg is then laid in the Megachile cell. The egg of the Coelioxys hatches before that of the Megachile and the newly-hatched larva crushes the Megachile egg with its large jaws. The Coelioxys larva can then feed on the contents of the cell. Pupation occurs within a cocoon spun within the host cell where the larva overwinters as a prepupa. The genus Anthophora excavates nest burrows in sandy soil or rotting wood, where they may also become the hosts of Coelioxys larvae. -

E-mail: [email protected] Abstract A new species, Polochridium spinosum Yue, Li & Xu, sp. nov. (China: Hunan, Shaanxi, Henan), is described and illus- trated. A key to the four Chinese species of Sapygidae is given. Key words: Sapyginae, new species, Palaearctic Region, Oriental Region Introduction Sapygidae is a small family of Vespoidea and includes 70 extant species in 12 genera (Aguiar et al. 2013; Achterberg 2014; Fernández & Sarmiento 2015), which are parasites of the bees Megachilidae, Apidae, Colletidae, rarely on wasps Eumeninae of Vespidae (Torchio 1979; Xu 1994; Kurzenko, 2012). Currently three species of the subfamily Sapyginae are known from China: Sapyga coma Yasumatsu & Sugihara, 1938, S. similis (Fabricius 1793), and Polochridium eoum Gussakovskij, 1932 (Kurzenko & Gusenleitner 1994; Xu 1994). Recently we collected in Hunan, Shaanxi and Henan fourteen females and one male of Polochridium, which described below as new species. Materials and methods Descriptions of the species have been made under a Leica MZ125 stereomicroscope, with lighting achieved through a 27W fluorescent lamp. Photographic images were produced with a digital camera Cool SNAP attached to the Zeiss Stemi 2000-cs stereomicroscope, and plates were finished with ACDSee 10.0 and Photoshop CS 8.0.1, mostly to adjust the size and background. -

Beyond the Decline of Wild Bees: Optimizing Conservation Measures and Bringing Together the Actors
insects Review Beyond the Decline of Wild Bees: Optimizing Conservation Measures and Bringing Together the Actors Maxime Drossart * and Maxence Gérard * Laboratory of Zoology, Research Institute for Biosciences, University of Mons (UMONS), Place du Parc 20, B-7000 Mons, Belgium * Correspondence: [email protected] (M.D.); [email protected] (M.G.) Received: 3 September 2020; Accepted: 18 September 2020; Published: 22 September 2020 Simple Summary: Wild bees represent the main group of pollinators in Europe, being responsible for the reproduction of numerous flowering plants. However, like a non-negligible part of biodiversity, this group has been facing a global decline mostly induced by numerous human factors over the last decades. Overall, even if all the questions are not solved concerning the causes of their decline, we are beyond the precautionary principle because the decline factors are roughly known, identified and at least partially quantified. Experts are now calling for effective actions to promote wild bee diversity and the enhancement of environmental quality. In this review, we present a general and up-to-date assessment of the conservation methods, as well as their efficiency and the current projects that try to fill the gaps and optimize the conservation measures. This publication aims to be a needed catalyst to implement concrete and qualitative conservation actions for wild bees. Abstract: Wild bees are facing a global decline mostly induced by numerous human factors for the last decades. In parallel, public interest for their conservation increased considerably, namely through numerous scientific studies relayed in the media. In spite of this broad interest, a lack of knowledge and understanding of the subject is blatant and reveals a gap between awareness and understanding. -
Pollinators in Peril: a Systematic Status Review of North American
POLLINATORS in Peril A systematic status review of North American and Hawaiian native bees Kelsey Kopec & Lori Ann Burd • Center for Biological Diversity • February 2017 Executive Summary hile the decline of European honeybees in the United States and beyond has been well publicized in recent years, the more than 4,000 species of native bees in North W America and Hawaii have been much less documented. Although these native bees are not as well known as honeybees, they play a vital role in functioning ecosystems and also provide more than $3 billion dollars in fruit-pollination services each year just in the United States. For this first-of-its-kind analysis, the Center for Biological Diversity conducted a systematic review of the status of all 4,337 North American and Hawaiian native bees. Our key findings: • Among native bee species with sufficient data to assess (1,437), more than half (749) are declining. • Nearly 1 in 4 (347 native bee species) is imperiled and at increasing risk of extinction. • For many of the bee species lacking sufficient population data, it’s likely they are also declining or at risk of extinction. Additional research is urgently needed to protect them. • A primary driver of these declines is agricultural intensification, which includes habitat destruction and pesticide use. Other major threats are climate change and urbanization. These troubling findings come as a growing body of research has revealed that more than 40 percent of insect pollinators globally are highly threatened, including many of the native bees critical to unprompted crop and wildflower pollination across the United States. -

Controlling of Insect-Parasites of Alfalfa Leafcutting Beestock (Megachile Rotundata F., Hymenoptera, Megachilidae)
CONTROLLING OF INSECT-PARASITES OF ALFALFA LEAFCUTTING BEESTOCK (MEGACHILE ROTUNDATA F., HYMENOPTERA, MEGACHILIDAE) Jenö FARKAS László SZALAY Zoltán TISZAI Research Centre for Animal Breeding and Nitti-itioit H-2100 GödöllÓ, P.O.B. 57, Hllngary SUMMARY Many millions of Megachile rotundata (Fabricius) prepupae were imported from the USA to Hungary between 1972 and 1978, but the general introduction of alfalfa leafcutting bee to Hungary planned for 1974 and 1975 could not be realized because of the heavy infestation by parasites. In 1981 we determined the Melittobia acastn Walker infestation of cocoons left behind by emerged alfalfa leafcutting bees. In 1982 we counted all the parasites emerged during the incubation period. In 1981 after the completion of incubation one male leafcutting bee and 4 913 Chalcidoidea emerged from the 1 200 leafcutting bee cocoons during 50 days ; they died without food within 10-14 days. Melittobia acasta Walker chosen randomly run towards day-light with a velocity of 9-14 m/h. In 1982 the number of emerged Megachile and Coelioxys increased by keeping the cocoons at lower temperatures and by treatment with Sevin, while the number of emerged Melittobia decreased. Besides the usual measurements new technological and management methods are needed in order to control the parasites. INTRODUCTION The alfalfa leafcutting bee, Megachile rotundata (Fabricius) has become one of the world’s most important pollinators of alfalfa. Most alfalfa seed growers who use this bee have substantially higher seed yields than those who rely on native pollination. Several bee species, including bumble bees and native leafcutting bees are efficient pollinators, but their populations fluctuate from year to year or even decrease as nesting habitats are reduced or destroyed by modern agricultural practices. -
Giant Resin Bee Megachile Sculpturalis (Smith) (Insecta: Hymenoptera: Megachilidae)1 Kristen C
EENY-733 Giant Resin Bee Megachile sculpturalis (Smith) (Insecta: Hymenoptera: Megachilidae)1 Kristen C. Stevens, Cameron J. Jack, and James D. Ellis2 Introduction Originally from eastern Asia, the giant resin bee, Megachile sculpturalis (Smith) (Figure 1), was accidentally introduced into the United States in the 1990s. It is considered an adventive species (i.e., non-native and usually not established), but is present in most states in the eastern US. Although these bees can be found on various plants, they typically prefer plants that have been introduced from their native area. Some have observed that when collecting pollen or nectar, Megachile sculpturalis will damage local flora, making them unusable to future bee visitors (Sumner 2003). Evidence has shown that Megachile sculpturalis pollinates a native and federally threatened plant, Apios Figure 1. A female giant resin bee, Megachile sculpturalis (Smith), pricenana (Campbell 2016). collecting pollen. Credits: Paula Sharp Distribution Megachile sculpturalis is native to China, Japan and a few other locations in eastern Asia. This bee was first inter- cepted in the US in North Carolina in 1994 at commercial ports; thus, it is believed to have arrived to the US ac- cidentally via international trade. Since coming to the US, it inhabits most states east of the Mississippi River. Based on its native range and preference for humid, subtropical, and temperate climates, it is predicted that this large invasive bee will continue to spread throughout the US (Parys et al. 2015) (Figure 2).
