Companion Planting and Insect Pest Control
Chapter 1 Companion Planting and Insect Pest Control Joyce E. Parker, William E. Snyder, George C. Hamilton and Cesar Rodriguez‐Saona Additional information is available at the end of the chapter http://dx.doi.org/10.5772/55044 1. Introduction There is growing public concern about pesticides’ non-target effects on humans and other organisms, and many pests have evolved resistance to some of the most commonly-used pesticides. Together, these factors have led to increasing interest in non-chemical, ecologically- sound ways to manage pests [1]. One pest-management alternative is the diversification of agricultural fields by establishing “polycultures” that include one or more different crop varieties or species within the same field, to more-closely match the higher species richness typical of natural systems [2, 3]. After all, destructive, explosive herbivore outbreaks typical of agricultural monocultures are rarely seen in highly-diverse unmanaged communities. There are several reasons that diverse plantings might experience fewer pest problems. First, it can be more difficult for specialized herbivores to “find” their host plant against a back‐ ground of one or more non-host species [4]. Second, diverse plantings may provide a broader base of resources for natural enemies to exploit, both in terms of non-pest prey species and resources such as pollen and nectar provided by the plant themselves, building natural enemy communities and strengthening their impacts on pests [4]. Both host-hiding and encourage‐ ment of natural enemies have the potential to depress pest populations, reducing the need for pesticide applications and increasing crop yields [5, 6]. On the other hand, crop diversification can present management and economic challenges for farmers, making these schemes difficult to implement. -
Characterization of Brassica Rapa Turnip Formation in Multiple Segregating Populations
Characterization of Brassica rapa turnip formation in multiple segregating populations Peter Vos 830317-908-030 Laboratory of Plant Breeding, Wageningen University January-October 2009 Supervisors: Ningwen Zhang Guusje Bonnema Characterization of Brassica rapa turnip formation in multiple segregating populations Abstract In this study eleven F 2 populations were evaluated for turnip formation (TuF) and flowering time (FT). The goal was to select populations which form turnips with a wide range in size for studying the genetic basis of turnip formation. Besides the turnip formation FT is important because in previous studies FT and turnip formation are negatively correlated and QTLs for both traits are mapped in the same genomic region. The major finding on the FT-TuF correlation topic was that the correlation was present when the parents differ greatly in flowering time, on the other hand the FT-TuF correlation was absent when the parents did not differ in flowering time. In the evaluated populations a distinction can be made between the origin of the turnips in the populations. Populations with turnips from the Asian and European centers of variation were represented in this study. The phylogenetic relationship between different turnips suggests that different genes could underlie turnip formation in both centers of variation. This hypothesis is confirmed; in a population between turnips from both centers of variation other genomic regions correlate with turnip size than regions in populations with only the Asian turnips. This indicates that different genes underlie the same trait in different centers of variation. However this is only one population and therefore the conclusion is still fragile. -

Mycosphere 10(1), 310–489, Doi 10.5943/mycosphere/10/1/7 Abstract Leotiomycetes is regarded as the inoperculate class of discomycetes within the phylum Ascomycota. Taxa are mainly characterized by asci with a simple pore blueing in Melzer’s reagent, although some taxa have lost this character. The monophyly of this class has been verified in several recent molecular studies. However, circumscription of the orders, families and generic level delimitation are still unsettled. This paper provides a modified backbone tree for the class Leotiomycetes based on phylogenetic analysis of combined ITS, LSU, SSU, TEF, and RPB2 loci. In the phylogenetic analysis, Leotiomycetes separates into 19 clades, which can be recognized as orders and order-level clades. -

Oliver6, Jonathan D. Moore7, Tim H. Mauchline2, Peter R. Mills8, Graham R. Teakle1, Ian M. Clark2, Penny R. Hirsch2, Christopher J. van der Gast9 and Gary D. Bending1* Abstract Background: The plant microbiome plays a vital role in determining host health and productivity. However, we lack real-world comparative understanding of the factors which shape assembly of its diverse biota, and crucially relationships between microbiota composition and plant health. Here we investigated landscape scale rhizosphere microbial assembly processes in oilseed rape (OSR), the UK’s third most cultivated crop by area and the world's third largest source of vegetable oil, which suffers from yield decline associated with the frequency it is grown in rotations. By including 37 conventional farmers’ fields with varying OSR rotation frequencies, we present an innovative approach to identify microbial signatures characteristic of microbiomes which are beneficial and harmful to the host. Results: We show that OSR yield decline is linked to rotation frequency in real-world agricultural systems. We demonstrate fundamental differences in the environmental and agronomic drivers of protist, bacterial and fungal communities between root, rhizosphere soil and bulk soil compartments. We further discovered that the assembly of fungi, but neither bacteria nor protists, was influenced by OSR rotation frequency. However, there were individual abundant bacterial OTUs that correlated with either yield or rotation frequency. -

Analysis of variance revealed significant differences (P ≤0.01) among Brassica napus genotypes for all the character studied except for oil content. Mean values showed that maximum for oil content (52.0 %) for genotype CH-4, protein content (22.6 %) for genotype PGRI-7, glucosinolate content (85.4 umolg -1) for genotype CH-4 and erucic acid content (59.2 %) for genotype CH-3. One the other hand, minimum mean values for genotype PGRI-7, oil content (47.3 %) for genotype CH-1, protein content (18.4 %) for genotype CH-2, glucosinolate content (49.0 umolg -1) for genotype CH-2, erucic acid content (35.0 %) for genotype CH-2. In addition, high broad sense heritability estimates were observed for erucic acid content (0.90), glucosinolate content (0.53), protein content (0.45) and oil content (0.16). In conclusion, significant differences among Brassica napus genotypes indicated sufficient variability among the tested material to have an effective selection. -
Winter Cutworm: a New Pest Threat in Oregon J
OREGON STATE UNIVERSITY EXTENSION SERVICE Winter Cutworm: A New Pest Threat in Oregon J. Green, A. Dreves, B. McDonald, and E. Peachey Introduction Winter cutworm is the common name for the larval stage of the large yellow underwing moth (Noctua pronuba [Lepidoptera: Noctuidae]). The cutworm has tolerance for cold temperatures, and larval feeding activity persists throughout fall and winter. Adult N. pronuba moths have been detected in Oregon for at least a decade, and the species is common in many different ecological habitats. Epidemic outbreaks of adult moths have occurred periodically in this region, resulting in captures of up to 500 moths per night. However, larval feeding by N. pronuba has not been a problem in Oregon until recently. In 2013 and 2014, there were isolated instances reported, including damage by larvae to sod near Portland and defoliation of herb and flower gardens in Corvallis. In 2015, large numbers of larvae were observed around homes, within golf courses, and in field crops located in Oregon and Washington. Winter cutworms have a wide host range across agricultural, urban, and natural landscapes (Table Photo: Nate McGhee, © Oregon State University. 1, page 2) and are a concern as a potential crop pest that can cause considerable damage in a short highlights general information about winter amount of time.
