Podium angustifrons Kohl 1902 is a species of solitary wasp which nests in pre-existing cavities, with neotropical distribution in Argentina, Bolivia, Brazil, Colombia, Guyana and French Guyana. The aim of this study was to investigate the nesting biology of P. angustifrons, discussing aspects of their life history. To capture its nests, wooden trap-nests were installed in the Parque Municipal das Araucárias, Guarapuava (PR), Brazil, from January 2003 to April 2009. A total of 29 nests were collected, all during the warmer months. These showed no vestibular and intercalary cells, and their closures were made up of chewed plants and mud mixed with organic materials and resin-coated surfaces, sometimes showing a layer of lichens. The cells were provisioned with various wild species of cockroaches (Chorisoneura sp, Riata sp and Helgaia sp) in the nymph stage and/or adults. The sex ratio was 4.6 females per male, significantly higher that the expected 1:1. Most pre-pupae entered diapause in winter with development time ranging from 187 to 283 days for females and 180 to 283 days for males. Deaths occurred in 41.66% of cells provisioned, 33.33% were attributed to faulty development and 8.33% to Chrysididae.

The nesting biology of Hoplitis producta has been reported by several authors, as the species is a common and widely distributed bee in North America east of the Rocky Mountains. Additional records, which have been obtained in connection with trap-nest research on bees and wasps in Wisconsin, are provided to supplement the previous reports.The nests were found in the pith at the butt ends of sumac stick trap-nests. A nest could be recognized readily because the 3 mm. plug that closed the burrow had a more solid texture and a darker color than the surrounding pith at the end of the stick. Rau (1928) found nests in tunnels of elder, sumac or rose stems but could not ascertain whether the bee excavated its own burrows or utilized burrows left by other twig-dwellers. Fischer (1955) stated that the female almost invariably excavated its own burrow. In Wisconsin, freshly cut sumac sticks were placed in the field in the spring; therefore, each of the following records represents a nest in a burrow excavated by the foundress bee.

Prey Items

Two females of Leptochilus regulus (de Saussure, 1855) were observed nesting in reed stalks of a Fabre’s hive serving as a block of trap nests in Crimea, with the timekeeping of all their nesting behaviours. The building material used by the females to separate the nesting cavity into the cells consisted of pellets of dry soil, gravel particles, and small fragments of tree bark, leaves, and thin stems. Females rapidly carried these items collected in 1.0–1.5 m from the nests. They bonded only the last portions of the building material in each “partition” with a very small amount of mud. An additional amount of unbonded building material items was deposited into the nest after sealing the last nest cell. Females hunted exclusively for small larvae of an anobiid beetle (Coleoptera, Anobiidae); they stored 19–37 prey items per cell. Hunting and provisioning occupied the largest portion of the females’ time budget. Duration of hunting flights was different between the females. The nests of both females contained three brood cells. Cocoons of Chrysis ragusae De Stefani, 1888 (Hymenoptera, Chrysididae) were found in the nests; females of this cuckoo wasp species were also recorded entering the host nests at the stage of provisioning, acting apparently as inquilines. The cocoon ultrastructure of L. regulus is illustrated and discussed.

Trap Nest

This study was carried in the Parque Municipal das Araucárias in the municipality of Guarapuava, state of Paraná, Southern Brazil. Three hundred and sixty five nests of T. lactitarse were obtained using trap-nests of 0.7, 1.0, and 1.3 cm in diameter. All of them had similar architecture, regardless of the diameter of the trap-nest. Completed nests consisted of a linear series of brood cells whose average number per nest was of 3.3, 4.0 and 3.6 for the nests with 0.7 cm, 1.0 cm and 1.3 cm in diameter, respectively. They were constructed more often during the summer. T. lactitarse had two types of life cycles: direct development (without diapause), and delayed development (with diapause during winter). Natural enemies included Chrysididae, Sarcophagidae, Dolichopodidae and Ichneumonidae. Out of 1,353 identified spider prey, 1,313 belonged to the Araneidae family.

By using trap nests, a total of 1,752 nests containing 3,405 provisioned cells of 33 species of solitary wasps and bees belonging to Vespidae, Sphecidae, Crabronidae, Pompilidae and Megachilidae families were collected in North Vietnam. Although the trap-nests are placed throughout the year, the nests were only collected in the period of seven months per year, from mid-April (or early May) to early November. A larger number of the nests (n = 1,607, or 91.72%) were occupied by wasp species and only 145 nests (8.28%) were occupied by bee species. In each family, Vespidae, Megachilidae, Sphecidae, Crabronidae and Pompilidae were represented by 12, 11, 7, 2 and 1 species, respectively. The dominant species were Pareumenes quadrispinosus, Rhynchium bruneum (Vespidae) and Chalybion malignum (Sphecidae). The nesting activities of wasps in the summer (May to July) were more active than in the autumn (August to early November), while the highest number of nests of bees were recorded in June, October and November. Tổng số 1.752 tổ chứa 3.405 khoang tổ của 33 loài ong bắt mồi thuộc các họ Vespidae, Sphecidae, Crabronidae, Pompilidae và ong mật họ Megachilidae đã được thu thập trong bẫy tổ ở miềm Bắc Việt Nam. Mặc dù các bẫy tổ được đặt trong cả năm nhưng tổ của các loài ong bắt mồi và ong mật chỉ thu được trong khoảng thời gian từ giữa tháng 4 (đầu tháng 5) đến đầu tháng 11. Phần lớn các tổ được làm bởi các loài ong bắt mồi (1.607 tổ chiếm 91,72%), chỉ có 145 tố chiếm 8,28% được làm bởi các loài ong mật. Số loài làm tổ thuộc các họ Vespidae, Megachilidae, Sphecidae, Crabronidae và Pompilidae tương ứnglần lượt là 12, 11, 7, 2 và 1. Trong đó có ba loài phổ biến là. Pareumenes quadrispinosus, Rhynchium bruneum (Vespidae) và Chalybion malignum (Sphecidae). Hoạt động làm tổ của các loài ong bắt mồi từ tháng 5 đến 7 diễn ra tích cực hơn so với từ tháng 8 đến 11, trong khi đó số tổ của các loài ong mật lại thu được nhiều nhất trong ba tháng 6, 10 và 11.

Nesting Activity

A total of 67 nests of Centris tarsata were obtained from wood trap-nests of different diameters, consisting of a linear series of brood cells built with sand mixed with oil. This species showed a preference for open habitats, since it occurred only in Swamp and Grassland areas and has never been found in the Araucaria forest. Nesting activity was bigger during the hot season, especially in December and January. The Sex ratio was of 1.48:1 (females/males), significantly different from 1:1. The females were larger than the males and these showed no dimorphism. Males were produced in the outermost cells and females in the innermost cells. C. tarsata presented a direct development without diapause in larval stage. They overwinter as adults. Development time was similar for males and females. Natural enemies are Bombyliidae Mesocheira bicolor, Coelioxys sp. and Meloidae.

Trap Nest

Cavity-nesting bees are enigmatic because they are difficult to observe in the wild, hence trap-nests (man-made cavities) provide the means by which these bees may be studied. Trap-nests is an efficient methodology to study these bees and are common worldwide. These traps have been used for a variety of reasons, including inventories, to examine pollen load, to study habitat disturbance, and bee conservation. However Neotropical trap-nesting bees’ taxonomy and biology are still poorly known and here we provide a review about these subjects. We searched for trap-nest bee studies in the Neotropical Region using Google Scholar and ISI Web of Science at any time in the past to December 2017. We found 109 independent studies, most of which were from Brazil (87 studies), followed by Argentina (10 studies), and other countries had fewer than five studies each. A total of 140 species, 24 genera, 10 tribes and three subfamilies were reported in trap-nests. Nest architecture was described for only 49 species. Taxonomy is only well-known for 14 genera, somewhat known for seven and is essentially unavailable for three genera. Construction material, closing plug and cell shape are similar among species in the same tribes and genera. Vestibular and intercalary cells, and the preliminary plug are variable, even at the specific level. Apinae is the most studied group with available data for all genera recorded in trap-nests. Colletinae is the least-studied group and nothing is known for their nesting biology. Megachilinae is intermediate, with some studies of taxonomy and nesting. We suggest that further trap-nest studies should provide more detailed information on nest architecture and construction materials, including explicit mention of structures that are absent. All Neotropical bees need more taxonomic studies, but some, such as Hylaeus and Megachile, require more attention since Hylaeus is essentially unknown and Megachile is very common on trap-nests.
