In this study, biological traits and population dynamics of this pest were investigated in Marivan region during 2004-2005. Results showed that this pest has 3 generations per year and main damage to canola caused by larvae of 3 rd generation that its adults emerged in mid of September. The larvae of first and second generations feed on weeds and vegetables in Brassicaceae family. The adult of first generation emerge at early of April and they mate immediately then lay the eggs. Maximum number of laid eggs by one female sawfly in laboratory condition was 57 and mean was 28.2 ±14. The average developmental periods of egg and larvae were 5.1 ±0.59 and 17.65 ± 1.57 days, respectively and the means of pupa stage for females and males were 9.8 ±1.29 and 12 ±1.95 days, respectively and total life span was 32-38 days. Average longevity of adult female and male was 9.4 ±2.24 and 5.7 ±1.42 days respectively. Sexual ratio (male: female) in the natural condition were 1: 2.68 and 1: 3.03 in 2004 and 2005 respectively. This insect overwinters as final instar larva in a coccon in a few centimeters deep in the soil. Key word: Athalia rosae , population dynamics, biology, Canola, Kurdistan.

  • Defence Mechanisms of Brassicaceae: Implications for Plant-Insect Interactions and Potential for Integrated Pest Management
    Agron. Sustain. Dev. 30 (2010) 311–348 Available online at: c INRA, EDP Sciences, 2009 www.agronomy-journal.org DOI: 10.1051/agro/2009025 for Sustainable Development Review article Defence mechanisms of Brassicaceae: implications for plant-insect interactions and potential for integrated pest management. 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.

However, if genomic sequencing is to be used for the improvement of human health, agriculture, and our understanding of biological systems, it is necessary to identify genes and understand how they contribute to biological outcomes. While there are several well-established workflows for assembling genomic sequences and identifying genes, understanding gene function is essential to create actionable knowledge.

  • A Linkage Map of the Turnip Sawfly Athalia Rosae (Hymenoptera: Symphyta) Based on Random Amplified Polymorphic Dnas
    Genes Genet. Syst.

Forty haploid male progeny (20 yfb and 20 +) from a single diploid female parent (yfb/+) were examined. Sixty-one of the 180 arbitrary primers tested by polymerase chain reaction (PCR) produced one or more RAPD bands. A total of 79 RAPD markers were detected. Of these, seven showed significant deviation from the expected 1:1 ratio, and were therefore excluded from further analysis. The remaining 72 RAPD markers and the marker mutation, yfb, were subjected to linkage analysis. Sixty RAPD markers and the yfb marker were organized into 16 linkage groups, spanning a distance of 517.2 cM. Twelve RAPD markers showed no linkage relationship to any group. Thirteen gel-purified RAPD bands were cloned and sequenced to generate the sequence-tagged sites (STSs).

This issue contains a variety of articles dealing with national and local recording, conservation status, behaviour and taxonomy. I am especially pleased that some of the notes in the last issue have been followed up and enhanced by what appears in this one. Because of costs, this is the last newsletter that will be sent out as printed copies unless specifically requested, so, if you have not already done so, please let me know if you can receive it electronically or require it on paper. Best wishes for a productive new year and please continue to send any contributions to me at the address above. RECENT LITERATURE This list is not exhaustive, but highlights some key literature and websites that have come to my attention in the past year. The end of last year saw the publication of the excellent Recent Sawfly Research: Synthesis and Prospects edited by S. Blank, S. Schmidt & A. Taeger (Goecke & Evers, Keltern, ISBN 3- 937783-19-9, 704pp). The book is a collection of about 40 papers detailing recent research on European and world sawfly life history & ecology, taxonomy, faunistics and checklists as well as reviews, biographies and a CD ROM of valuable ‘historic’ literature and colour plates. Several of the papers mentioned as ‘in prep’ or ‘in press’ in the note on recent additions to the British list in the last newsletter have now been published.

However, 22 little is known about how these parental life stage-specific environments interact with 23 each other and with the offspring environment to influence offspring phenotypes, 24 particularly in organisms that realize distinct niches across ontogeny. We examined 25 the effects of parental early life starvation and adult reproductive environment on 26 offspring traits under matching or mismatching offspring early life starvation 27 conditions using the insect Athalia rosae (turnip sawfly).
