The pest is known to feed primarily on maize which is a staple food in the continent. Since then, farmers have been using chemical insecticides to control the pest. Chemical insecticides are expensive and harmful to the environment. In this article, the authors Albasini Caniço, António Mexia, and Luisa Santos discuss the possibility of application of an alternative method of control known to be environmentally friendly and economically sustainable in the long term. The method, known as “biological control”, can be easily implemented by farmers, and has the potential to reduce the population of the insect pest and production costs, and bring long term benefits to the environment.

  • Metopiinae (Hymenoptera: Ichneumonidae) from Bulgaria and Related Regions

Beitr. 46/2 1343-1351 19.12.2014 Metopiinae (Hymenoptera: Ichneumonidae) from Bulgaria and related regions Janko KOLAROV A b s t r a c t . The newly discovered female of Exochus hirsutus TOLKANITZ is described and figured. Data of 40 Metopiinae species from Bulgaria and related regions are presented. Of them 19 species are new records to the Bulgarian fauna, 3 species new to Macedonia, 12 species new to Greece, 3 species new to Turkey and 1 species new to Iran (marked in the text by asterisk). K e y w o r d s : Metopiinae, Ichneumonidae, Bulgaria, new records, description. Introduction Metopiinae is a medium-sized ichneumonid subfamily comprising 22 genera and about 660 species worldwide (YU & HORSTMANN 1997). They are koinobiont endoparasitoids of lepidopterous larvae, living usually in leaf rolls or folds on plants. Oviposition takes place into the host larva, but the adult emergence always occurs from the pupa. A key to the genera is given by TOWNES (1971). The Bulgarian Metopiinae fauna is not well studied. The first reports were made by TSCHORBADJIEW (1925). Until now 49 species from Bulgaria were reported mainly by GREGOR (1933), ANGELOV & GEMANOV (1969), GERMANOV (1980) and KOLAROV (1984). In the present paper data for 40 species are given. Of them 19 species are new records to the Bulgarian fauna, 3 species new to Macedonia, 12 species new to Greece, 3 species new to Turkey and 1 species new to Iran. For the other species new localities are added. The newly discovered female of Exochus hirsutus TOLKANITZ is described and figured for the first time.

  • Identification Key to the Subfamilies of Ichneumonidae (Hymenoptera)
    Identification key to the subfamilies of Ichneumonidae (Hymenoptera) Gavin Broad Dept. of Entomology, The Natural History Museum, Cromwell Road, London SW7 5BD, UK Notes on the key, February 2011 This key to ichneumonid subfamilies should be regarded as a test version and feedback will be much appreciated (emails to [email protected]). Many of the illustrations are provisional and more characters need to be illustrated, which is a work in progress. Many of the scanning electron micrographs were taken by Sondra Ward for Ian Gauld’s series of volumes on the Ichneumonidae of Costa Rica. Many of the line drawings are by Mike Fitton. I am grateful to Pelle Magnusson for the photographs of Brachycyrtus ornatus and for his suggestion as to where to include this subfamily in the key. Other illustrations are my own work. Morphological terminology mostly follows Fitton et al. (1988). A comprehensively illustrated list of morphological terms employed here is in development. In lateral views, the anterior (head) end of the wasp is to the left and in dorsal or ventral images, the anterior (head) end is uppermost. There are a few exceptions (indicated in figure legends) and these will rectified soon. Identifying ichneumonids Identifying ichneumonids can be a daunting process, with about 2,400 species in Britain and Ireland. These are currently classified into 32 subfamilies (there are a few more extralimitally). Rather few of these subfamilies are reconisable on the basis of simple morphological character states, rather, they tend to be reconisable on combinations of characters that occur convergently and in different permutations across various groups of ichneumonids.

PRICE Department of Entomology,University of Illinois, Urbana, Illinois 61801 Two closely related approaches to the study of reproductivestrategies have been pursued with success.Differences in timingof reproductiveeffort were explored in attemptingto explain the adaptive nature of differences in life historiesof organismsin the same taxonomicgroup (e.g., Cole 1954; Lewontin 1965; Murdoch 1966a, 1966b; Tinkle 1969; Emlen 1970; Gadgil and Bossert 1970). The other avenue of investigationhas concentratedon numbers of progeny produced, particularly clutch size (e.g., Lack 1954; Cody 1966). The latter approach appears to be the more rewarding in relationto an insect taxon where femalesusually ovipositsoon after emer- genceor as soon as hostsbecome available and in whichare containedspecies showingextremes in total fecuundity.

  • Ichneumon Sub-Families This Page Describes the Different Sub-Families of the Ichneumonidae
    Ichneumon Sub-families This page describes the different sub-families of the Ichneumonidae. Their ecology and life histories are summarised, with references to more detailed articles or books. Yorkshire species from each group can be found in the Yorkshire checklist. An asterix indicates that a foreign-language key has been translated into English. One method by which the caterpillars of moths and sawflies which are the hosts of these insects attempt to prevent parasitism is for them to hide under leaves during the day and emerge to feed at night. A number of ichneumonoids, spread through several subfamilies of both ichneumons and braconids, exploit this resource by hunting at night. Most ichneumonoids are blackish, which makes them less obvious to predators, but colour is not important in the dark and many of these nocturnal ones have lost the melanin that provides the dark colour, so they are pale orange. They have often developed the large-eyed, yellowish-orange appearance typical of these nocturnal hunters and individuals are often attracted to light. This key to British species is a draft: http://www.nhm.ac.uk/resources-rx/files/keys-for-nocturnal-workshop-reduced-109651.pdf Subfamily Pimplinae. The insects in this subfamily are all elongate and range from robust, heavily- sculptured ichneumons to slender, smooth-bodied ones. Many of them have the 'normal' parasitoid life-cycle (eggs laid in or on the host larvae, feeding on the hosts' fat bodies until they are full- grown and then killing and consuming the hosts) but there are also some variations within this subfamily.

Introduction The Metopiinae is a medium-sized cosmopolitan The purpose of this paper is to present the description subfamily of Ichneumonidae with members distinguished of two new species of Neotropical Metopiinae to make by having the lower face and clypeus confluent and not the names available. separated by an impressed groove; most species possess a shelf-like protuberance below the antennal insertion and 2. Material and Methods having the pronotum laterally concave and rather broadly rounded posteriorly, broadly occluding the spiracular Most of the specimens for this study were collected sclerite.

  • Subfamily Composition of Ichneumonidae (Hymenoptera) from Western Amazonia: Insights Into Diversity of Tropical Parasitoid Wasps
    Insect Conservation and Diversity (2012) doi: 10.1111/j.1752-4598.2012.00185.x Subfamily composition of Ichneumonidae (Hymenoptera) from western Amazonia: Insights into diversity of tropical parasitoid wasps ANU VEIJALAINEN,1 ILARI E.

Previous studies have found the parasitoid wasp family Ichneumonidae (Hymenoptera) to have an exceptional latitudinal species richness gradient that peaks at mid-latitudes instead of the tropics; however, insufficient tropical sampling and species description may have biased the conclusions. It has been unclear which subfamilies might be species rich in tropical lowland rain forests. 2. This study reports the subfamily abundance composition of a large ichneumo- nid data set (>30 000 individuals in 20 subfamilies) collected by Malaise traps and insecticidal canopy fogging in Amazonian Ecuador and Peru and suggests which subfamilies would be important for future study. 3. Relative abundance data from one Peruvian site are compared to similar low- land samples from Costa Rica and Georgia (USA). 4. Contrary to a common assumption, a number of ichneumonid subfamilies are very abundant and presumably species rich in western Amazonia. Cryptinae and Or- thocentrinae are noticeably the two most abundant subfamilies, and a number of koinobiont lepidopteran parasitoids, which are generally thought to be scarce in the tropics, are also surprisingly abundant (e.g.
