It was expected [email protected] that linseed seeding density can signifi cantly aff ect fl ea beetle populations. Th e experiment was carried out in Lower Silesia, Poland, from 2011 to 2013. A genetically modifi ed type of linseed overproducing fl avonoids was used. Flea beetles and the damages they caused were determined on plants and also a sweep net was used for the collection of adult beetles. Dur- ing the three years of the study 15 species of fl ea beetles were identifi ed from oil fl ax plants, with A. euphorbiae and L. parvulus being dominant. In terms of the total catch, the tendency was for beetle numbers to decrease with increasing plant density. Flax fl ea beetles feeding on linseed plants, irrespective of plant density, had two peaks of abundance. Th e fi rst peak was lower and occurred in June, when plants were at the blooming stage. Th is peak was caused by overwintering adults who colonized crops in spring. Th e second, higher peak of abundance was recorded in the second half of July, when plants were at the ripening stage. Th is peak was formed by adults of the new generation. Each year, at the higher population peak of abun- dance, the fl ea beetles were most numerous on plants grown at the lowest density. Th ere was one period, lasting either from mid-May to the fi rst few days of June, or from the beginning of June to mid-June, during which the number of holes and damage on plants of each treat- ment were highest. During the three years of the study there were several cases of signifi cantly higher numbers of fl ea beetle feeding symptoms on plants grown at the lowest density as compared to the medium and highest densities.

A review Ishita Ahuja,JensRohloff, Atle Magnar Bones* Department of Biology, Norwegian University of Science and Technology, Realfagbygget, NO-7491 Trondheim, Norway (Accepted 5 July 2009) Abstract – Brassica crops are grown worldwide for oil, food and feed purposes, and constitute a significant economic value due to their nutritional, medicinal, bioindustrial, biocontrol and crop rotation properties. Insect pests cause enormous yield and economic losses in Brassica crop production every year, and are a threat to global agriculture. In order to overcome these insect pests, Brassica species themselves use multiple defence mechanisms, which can be constitutive, inducible, induced, direct or indirect depending upon the insect or the degree of insect attack. Firstly, we give an overview of different Brassica species with the main focus on cultivated brassicas. Secondly, we describe insect pests that attack brassicas. Thirdly, we address multiple defence mechanisms, with the main focus on phytoalexins, sulphur, glucosinolates, the glucosinolate-myrosinase system and their breakdown products. In order to develop pest control strategies, it is important to study the chemical ecology, and insect behaviour. We review studies on oviposition regulation, multitrophic interactions involving feeding and host selection behaviour of parasitoids and predators of herbivores on brassicas. Regarding oviposition and trophic interactions, we outline insect oviposition behaviour, the importance of chemical stimulation, oviposition-deterring pheromones, glucosinolates, isothiocyanates, nitriles, and phytoalexins and their importance towards pest management.

Many Flea Beetles are among the most affective jumpers in the animal kingdom, sometimes better than their namesakes the true Fleas (Siphonaptera). However, despite some intensive study of the anatomy and function of the metafemoral spring (Barth, 1954; Ker, 1977) the true function of this jumping mechanism remains a mystery. It probably is some sort of voluntary Catch, in- volving build-up of tension from the large muscles that insert on the metafemoral spring (Fig. 1), and theo a quick release of this energy. Ofcourse some Flea Beetles jump better than others, but basically all have this internal metafemoral spring floating by attachment from large muscles in the relatively enlarged bind femoral capsule (see Fig. 1 ). In fact Flea Beetles can usually be easily separated from other beetles, including chrysomelid subfa- milies, by their greatly swollen bind femora. There are a few genera of Alticinae that have a metafemoral spring and yet do not jump. Actually there are a few genera that are considered to be Alticinae that lack the metafemo- ral spring, e. g. Orthaltica (Scherer, 1974, 1981b - as discussed in this Symposium). Also the tribe Decarthrocerini contains three genera from Africa that Wilcox (1965) con- sidered as Galerucinae, but now thinks to be intermediate between Galerucinae and Alti- cinae; at least one of these genera does have a metafemoral spring (Wilcox, personal communication, and Fürth, unpublished data).

  • Leaf Beetle Larvae
    Scottish Beetles BeesIntroduction and wasps to Leaf Beetles (Chrysomelidae) There are approximately 281 species of leaf beetles in the UK. This guide is an introduction to 17 species found in this family. It is intended to be used in combination with the beetle anatomy guide and survey and recording guides. Colourful and often metallic beetles, where the 3rd tarsi is heart shaped. Species in this family are 1-18mm and are oval or elongated oval shaped. The plants each beetle is found on are usually key to their identification. Many of the species of beetles found in Scotland need careful examination with a microscope to identify them. This guide is designed to introduce some of the leaf beetles you may find and give some key Dead nettle leaf beetle (Chrysolina fastuosa ) 5-6mm This leaf beetle is found on hemp nettle and dead nettle plants.

Specifically, this area is composed of various habitats, including forests, open soils, ruderal habitats and a sewage water body. Based on our findings, we suggest appropriate interventions or changes in management to support and enhance local biodiversity. Our results showed that species composition of plants and animals in the quarry premises is characterized mostly by common species (with only few plant taxa exception) without any specific habitat requirements. We found that the most botanically valuable habitats in Bobroviště are the forest fragment and the spring with its immediate vicinity. Since wetland habitats became valuable in the respect of climate changes in the last few years, we suggest creating new ponds and a littoral zone in the sewage water body to enhance biodiversity of this area and consequently increase water retention in the landscape. Introduction Mining areas are often perceived by the public as a scar on the landscape.

Munis Entomology & Zoology, 11 (2): 682-690] ABSTRACT: This work is presented a comparative list of the leaf beetles of the provinces in Marmara Region of Turkey, excluding Bruchinae. All known taxa from the provinces in Marmara Region of Turkey and thereby European Turkey are given in the present text. KEY WORDS: Coleoptera, Cerambycidae, European Turkey, Marmara Region, Turkey Any direct research on leaf beetles in Marmara Region of Turkey is not present. Therefore fauna of leaf beetles in Marmara Region of Turkey is not sufficiently known. Chiefly, a complete faunistic information about all the leaf beetle taxa established in European Turkey in Marmara Region of Turkey was firstly published by Löbl & Smetana (2010) in their Palaearctic catalogue of Chrysomeloidea. Then, an important study titled “Checklist of leaf beetles (Coleoptera: Chrysomelidae) of Turkey, excluding Bruchinae” was published by Ekiz et al. (2013). Later works were published by Özdikmen (2014a,b,c), Özdikmen & Kaya (2014), Özdikmen & Mercan (2014), Özdikmen & Cihan (2014), Özdikmen & Özbek (2014), Özdikmen & Kavak (2014) and Özdikmen & Topcu (2014). Although the mentioned studies helped to determine the list of leaf beetles from the provinces in Marmara Region of Turkey, the list needs further corrections to be fully and correctly realized.

Biotic interactions between co-occurring species, however, are an important additional influence. We review the impor- tance of interactions with food and nectar plants (as resources) in determining the distribution of phytophagous and pollinating insects (as consumers). We use biological recording datasets for seven taxonomic groups to quantify the relationship between the geographical distributions within Britain of 1265 phytophagous insects and their associated food plants, representing 9128 interactions in total. We find a consistent pattern across taxonomic groups in that individual phytophagous insect species rarely utilize the full range of their food plants and the relationship between the range sizes of insects and their food plants is not a simple linear one. For a small selection of phytophagous species where data are available, we highlight an association between changes in range and interactions with associated food plant species. Climate-driven range expansion may be constrained through disruption of trophic relationships between phytophagous insects and their food plants if they respond differently to abiotic drivers.
