  • Invasive Plant Mapping Protocols
    For more information: [email protected] Invasive Species Mapping Protocols Objective The objective for creating these mapping protocols is to develop a unified database of invasive species occurrences within the Midwest region of the United States. These protocols were created in partnership with the Michigan Invasive Species Coalition (MISC). These guidelines will assist all partners within the region in documenting the occurrence and spread of invasive species. The data collected will allow for the development and implementation of effective control strategies in the region. Documentation: All information about invasive species occurrences must be documented using the categories on the official data form. All locations must be recorded using GPS. New occurrences should be marked with flagging ONLY if necessary to help relocate the invasive species for treatment. Volunteers must obtain permission before using flagging. The use of flagging or other references should be noted on the data form under the comments section. All equipment, materials and instructions will be provided by project partners as needed. GPS Protocols: For all observations, record a point location in the center of each population. If the area is heavily infested and distinct populations can be easily seen one to the next, mark no more than ONE point per 100ft. An average of 25 points should be taken per waypoint. All GPS points must be labeled with a unique ID number using the numbering convention explained below. Unique ID: For each GPS position collected, record a unique twelve or thirteen digit number (depending on the invasive species code) in the GPS unit for each point as follows: “BBJJGM00141U” where BB is the two letter code for the natural area, JJ is the mapper’s initials, GM is the invasive species code, 001 is the three digit sequence number, 4 is the area, 1 is the sparse density, and U is for untreated.

Most trap crops in the order Brassicales target insects that 27 are specialist in plants belonging to this order, such as the diamondback moth, Plutella 28 xylostella L. (Lepidoptera: Plutellidae), the pollen beetle, Meligethes aeneus Fabricius 29 (Coleoptera: Nitidulidae), and flea beetles inthe genera Phyllotreta Psylliodes 30 (Coleoptera: Chrysomelidae). In most cases, the mode of action of these trap crops is the 31 preferential attraction of the insect pest for the trap crop located next to the main crop. 32 With one exception, these trap crops in the order Brassicales have been used with 33 brassicaceous crops. Insectary plants in the order Brassicales attract a wide variety of 34 natural enemies, but most studies focus on their effect on aphidofagous hoverflies and 35 parasitoids. The parasitoids benefiting from insectary plants in the order Brassicales 36 target insects pests ranging from specialists, such as P. xylostella, to highly polyfagous, 37 such as the stink bugs Euschistus conspersus Uhler and Thyanta pallidovirens Stål 38 (Hemiptera: Pentatomidae).

  • Responses of the Swede Midge, Contarinia Nasturtii, to Volatile Compounds from Arabidopsis Thaliana and Brassica Oleracea Var
    Master project in the Horticultural Science Programme 2008-02, 20 p (30 ECTS) Responses of the swede midge, Contarinia nasturtii, to volatile compounds from Arabidopsis thaliana and Brassica oleracea var. botrytis Photo: Linda-Marie Rännbäck by Johannes Albertsson Fakulteten för landskapsplanering, trädgårds- och jordbruksvetenskap SLU-Alnarp PROJECT INFORMATION This report is a result of a master thesis (30 ects) carried out at the department of Plant Protection Biology within the Horticultural programme at the Swedish University of Agricultural Sciences. Tina Boddum and Ylva Hillbur were supervisors and Peter Anderson was the examiner. 2 ABSTRACT The swede midge, Contarinia nasturtii, is a serious gall-forming insect pest of most cultivated Brassicaceae such as cauliflower and cabbage. Arabidopsis thaliana, also a Brassicaceae, is a well-known model plant for which the genome is sequenced and several well-characterized mutants and transgenic genotypes are available. Previous results indicate that odours from cauliflower attract C. nasturtii. In this study the responses of C. nasturtii to volatiles from cauliflower and Arabidopsis were tested in a four-arm and a y-tube olfactometer. The results indicate that females are attracted to volatiles both from cauliflower and Arabidopsis. Males on the other hand were not attracted. This study also suggests improvements for the y-tube as well as a four-arm olfactometer setup. SAMMANFATTNING Kålgallmyggan, Contarinia nasturtii, är en skadegörare på flertalet odlade grödor tillhörande familjen Brassicaceae så som blomkål, vitkål och broccoli. Arabidopsis thaliana, som också tillhör denna familj, är en viktig modellväxt eftersom dess genom helt är kartlagt och att en mängd väldokumenterade mutationer och transgena genotyper finns tillgängliga.

  • Gall Midges (Diptera: Cecidomyiidae) of South Tyrol (Italy) - Summary of Results and Zoogeographical Analysis
    Gredleriana Vol. 10 / 2010 pp. 275 - 324 Gall midges (Diptera: Cecidomyiidae) of South Tyrol (Italy) - summary of results and zoogeographical analysis Gallmücken (Diptera: Cecidomyiidae) Südtirols – zusammenfassende Resultate und zoogeographische Analyse Marcela Skuhravá and Václav Skuhravý Abstract At present the gall midge fauna of South Tyrol includes 311 species in 68 genera. A total of 271 species are valid and 40 species, still undescribed, are identified to the generic level. Investigations were carried out at 124 localities at altitides from 250 m a.s.l. at Salurn to 2581 m a.s.l. at Schaubachhütte in the Ortler Range during the period 1999-2009. Zoogeographical analysis is based on 2150 records, of which 200 were obtained by earlier researchers and 1950 records of the present authors. Until 1996 only 24 species were known to occur in South Tyrol. We enriched the faunal list of South Tyrol by adding 287 species and the faunal list of Italy by 114 species. A list of gall midge species and a list of host plants attacked by gall midges are given. Diversity ranged from 3 to 36 species at a single locality. On average we determined 15 species to occur per locality in South Tyrol. Species number declines with increasing elevation. Density is high at 189 species per 1000 km2. South Tyrol is one of the best explored areas of the world for galls of Cecidomyiidae. Frequency of occurrence: 49 % species occur very rarely, 21 % rarely, 17 % moderately frequently, 9 % frequently, 4 % very frequently. Iteomyia capreae is the most frequently recorded species in South Tyrol.

  • Swede Midge (Contarinia Nasturtii) Has Become a Problematic Pest on Small-Scale Organic Farms in the Belgian Regions Antwerp and Flemish Brabant
    Control of swede midge on organic CSA-farms [email protected] Swede midge (Contarinia nasturtii) has become a problematic pest on small-scale organic farms in the Belgian regions Antwerp and Flemish Brabant. In recent years farmers suffered economic losses to the extent that it threatens the entire cabbage production on the farm. Farmers of the CSA-Network work according the principle of ‘community supported agriculture’ and grow multiple crucifer crops. Aim of the Operational Group • start a monitoring on farms where previous history of damage; • establish an effective and feasible management strategy in line with the CSA farming system; • raise the awareness within the whole grower’s network on the pest issue. Monitor population abundance and timing Evaluation of plant damage Pherobank BV (NL) synthesized three pheromone Samples of infested plants were collected to check for the compounds and formulated an optimal blend in ready-for- presence of larvae inside growing tips. use lures. These are applied in transparent delta traps for swede midge specific monitoring.

  • Insect Derived Extra Oral GH32 Plays a Role in Susceptibility of Wheat to Hessian Fy Subhashree Subramanyam1,2*, Jill A
    www.nature.com/scientificreports OPEN Insect derived extra oral GH32 plays a role in susceptibility of wheat to Hessian fy Subhashree Subramanyam1,2*, Jill A. Nemacheck1,2, Victor Bernal‑Crespo3 & Nagesh Sardesai4 The Hessian fy is an obligate parasite of wheat causing signifcant economic damage, and triggers either a resistant or susceptible reaction. However, the molecular mechanisms of susceptibility leading to the establishment of the larvae are unknown. Larval survival on the plant requires the establishment of a steady source of readily available nutrition. Unlike other insect pests, the Hessian fy larvae have minute mandibles and cannot derive their nutrition by chewing tissue or sucking phloem sap. Here, we show that the virulent larvae produce the glycoside hydrolase MdesGH32 extra‑orally, that localizes within the leaf tissue being fed upon. MdesGH32 has strong inulinase and invertase activity aiding in the breakdown of the plant cell wall inulin polymer into monomers and converting sucrose, the primary transport sugar in plants, to glucose and fructose, resulting in the formation of a nutrient‑rich tissue. Our fnding elucidates the molecular mechanism of nutrient sink formation and establishment of susceptibility. Signifcant global economic damage is caused by the infestation of maize, wheat and rice by insect pests, resulting in annual production losses ranging from around 45–75 metric megatons1. While there are several factors that play crucial roles in defense, the plant cell wall, composed of a heterogeneous mixture of high-molecular weight complex polysaccharides such as cellulose, hemicellulose, pectin, and diverse proteins, in addition to provid- ing structural support, is the primary line of defense against pests 2.
