“…Los Amigos Conservation Concession (12°33‐34′ S, 70°04‐05′ W) is located in the southern Peruvian Amazonia in the department of Madre de Dios close to the Andean‐Amazonian interface. Mean annual precipitation is about 2770 mm and annual mean temperature 23 °C with monthly mean temperatures varying 20–26 °C (Gómez et al ., ). This is somewhat drier, cooler and more seasonal than in Allpahuayo‐Mishana.…”

The old idea that parasitoid wasps (Ichneumonidae) show an inverse latitudinal diversity gradient has recently been challenged, but how ichneumonid species richness varies across the globe is still not well understood. We carried out field inventories in 21 sites on three continents to clarify this question, focusing on the subfamilies Pimplinae and Rhyssinae. Our total sampling effort was 628 Malaise trap months and the total catch exceeded 65 000 individuals. Our main focus was in two intensively inventoried areas in Amazonia, together yielding 257 Malaise trap months and 26 390 ichneumonid individuals. To expand the scope and assess global species diversity patterns of the Pimplinae and Rhyssinae, we compiled published species lists from a total of 97 study localities around the world. The highest observed species richness in any locality, 105 species, was found in one of our field sites in Peruvian Amazonia. None of the other localities reported more than 70 species, even the ones with a sampling effort comparable to ours. Despite the local thoroughness of our field inventories in Amazonia, data analyses indicated that a substantial proportion of the parasitoid wasp species occurring in each site remained unobserved. The highest local species richness values were reported from the tropics. Nevertheless parasitoid wasps are still too sparsely sampled to draw solid conclusions about whether or not their species richness follows a particular latitudinal trend, and if so, where their richness peaks.

“…Following Kunz (1988), we invested effort in trapping insects from the same location where the bats foraged. To assess insect availability, we used two widely used and efficient trap types (S€ a€ aksj€ arvi et al 2004Gomez et al 2009;Janzen et al 2009;Lilley et al 2012;Veijalainen et al 2012Veijalainen et al , 2013: emergence traps (E.

What you need is what you eat? Prey selection by the bat Myotis daubentonii

Optimal foraging theory predicts that predators are selective when faced with abundant prey, but become less picky when prey gets sparse. Insectivorous bats in temperate regions are faced with the challenge of building up fat reserves vital for hibernation during a period of decreasing arthropod abundances. According to optimal foraging theory, prehibernating bats should adopt a less selective feeding behavior--yet empirical studies have revealed many apparently generalized species to be composed of specialist individuals. Targeting the diet of the bat Myotis daubentonii, we used a combination of molecular techniques to test for seasonal changes in prey selectivity and individual-level variation in prey preferences. DNA metabarcoding was used to characterize both the prey contents of bat droppings and the insect community available as prey. To test for dietary differences among M. daubentonii individuals, we used ten microsatellite loci to assign droppings to individual bats. The comparison between consumed and available prey revealed a preference for certain prey items regardless of availability. Nonbiting midges (Chironomidae) remained the most highly consumed prey at all times, despite a significant increase in the availability of black flies (Simuliidae) towards the end of the season. The bats sampled showed no evidence of individual specialization in dietary preferences. Overall, our approach offers little support for optimal foraging theory. Thus, it shows how novel combinations of genetic markers can be used to test general theory, targeting patterns at both the level of prey communities and individual predators.

“…Xanthopimpla species can be recognized by yellow body with stout legs and variables spots or black bands on abdominal tergites .Bidentate mandibles and lower teeth twisted are two characters which differentiate this genus from others (Gauld, 1984). A lot of faunal studies of this genus from different regions of the world include Thunberg (1822); Saussure (1892) and Krieger (1914) from Palearctic region; Tosquinet (1896) and Seyrig (1932) from Afrotropical region; Townes 1969 andGómez et al (2009;2014) from Neotropical regions and Townes & Chiu (1970), Gupta (1987), Pham et al (2011) from oriental regions etc.…”

Members of Genus Xanthopimpla Saussure, 1892 (Hymenoptera: Ichneumonidae: Pimplinae) are reported as important bio-control agents of different insect pests of various crops. Four species were recorded from Pothwar region with Xanthopimpla reicherti Krieger, 1914 as new record for Pakistan. New distributional records for Xanthopimpla punctata Fabricius, 1781, Xanthopimpla stremmator Thunberg 1822, and Xanthopimpla flavolineata Cameron, 1907 in Pothwar have been added. Comparison of recorded species with closely related species, distribution ranges, and remarks on their host are given. An identification key of recorded species, as well as brief description of each species has been provided, and supplemented with illustrations using microphotography from the external morphological details. Arc GIS software was used for spatial distribution of identified species. Results of these studies including illustrations may be helpful for field workers for identification and researchers to formulate IPM strategies against various insect pests of crops in different districts of Pothwar region of Pakistan.
