197 Section 9 Sunflower (Helianthus
SECTION 9 SUNFLOWER (HELIANTHUS ANNUUS L.) 1. Taxonomy of the Genus Helianthus, Natural Habitat and Origins of the Cultivated Sunflower A. Taxonomy of the genus Helianthus The sunflower belongs to the genus Helianthus in the Composite family (Asterales order), which includes species with very diverse morphologies (herbs, shrubs, lianas, etc.). The genus Helianthus belongs to the Heliantheae tribe. This includes approximately 50 species originating in North and Central America. The basis for the botanical classification of the genus Helianthus was proposed by Heiser et al. (1969) and refined subsequently using new phenological, cladistic and biosystematic methods, (Robinson, 1979; Anashchenko, 1974, 1979; Schilling and Heiser, 1981) or molecular markers (Sossey-Alaoui et al., 1998). This approach splits Helianthus into four sections: Helianthus, Agrestes, Ciliares and Atrorubens. This classification is set out in Table 1.18. Section Helianthus This section comprises 12 species, including H. annuus, the cultivated sunflower. These species, which are diploid (2n = 34), are interfertile and annual in almost all cases. For the majority, the natural distribution is central and western North America. They are generally well adapted to dry or even arid areas and sandy soils. The widespread H. annuus L. species includes (Heiser et al., 1969) plants cultivated for seed or fodder referred to as H. annuus var. macrocarpus (D.C), or cultivated for ornament (H. annuus subsp. annuus), and uncultivated wild and weedy plants (H. annuus subsp. lenticularis, H. annuus subsp. Texanus, etc.). Leaves of these species are usually alternate, ovoid and with a long petiole. Flower heads, or capitula, consist of tubular and ligulate florets, which may be deep purple, red or yellow. -

The effectiveness of the system was studied by tak- ing photos of 165 insect species including some subspecies from museum collections (105 Coleoptera, 11 Hemi ptera (Pentatomidae), 12 Hymenoptera, 10 Lepidoptera, 9 Mantodea, 4 Odonata, 13 Orthoptera, 1 Phasmatodea) and 16 living insect species (1 Lepidoptera, 3 Mantodea, 4 Orthoptera, 8 Phasmato- dea), from which four are exemplarily pictured herein. The system is based on a modifi ed standard consumer DSLR camera (Canon Rebel XSi), which was altered for two-channel colour infrared photography. The camera is especially sensitive in the spectral range of 700-800 nm, which is well- suited to visualize small scale spectral differences in the steep of increase in refl ectance in this range, as it could be seen in some species. Several of the investigated species show at least a partial infrared refl ectance. -
Marvellous Monsters Fact File
MARVELLOUS MONSTERS FACT FILE Inside this booklet, you will find some monstrous facts and information about the marvellous mini-beasts you can see at Longleat this year. BEETLES Coleoptera Beetles make up the largest group of insects with at least 350,000 known species across the world and make up around a quarter of all know species on the planet! They include some beetles well-known to us such as the ladybird and in the UK, we have at least 4000 different species. • Beetles have a distinct lifecycle and can spend several years as larvae before emerging as an adult. • Beetles have an elytra which is a pair of modified wings that have hardened to form a wing case, thus beetles fly with one pair of wings. • Beetles play a number of ecological roles. They can be detritivores, recycling nutrients such as plant materials, corpses and dung. They can act as pollinators and predators to pest species. They have been revered such as the sacred scarab beetle by ancient Egyptians and loathed as pests such as the death watch beetle. They are a fascinating and diverse group of animals and well worth exploring in more detail. BEETLES HERCULES BEETLE Dynastes hercules Classification Phylum - Arthropoda Class - Insecta Order - Coleoptera Location Southern USA, Mexico, Bolivia Size Up to 180mm long Where are they found? Understorey and forest floor amongst leaves, rotting wood and fruit Diet They are detritivores, so they eat dead and rotting fruit that has fallen to the ground. This is one of the largest beetles in the world. The male is easy to identify with one long horn coming from the thorax and one from the head. -

Sunflower Maggot: Strauzia Longipennis
Plant Pest Factsheet Sunflower maggot Strauzia longipennis Figure 1. Adult Strauzia longipennis, Washington, USA. © Katja Schulz. Background Strauzia longipennis (Wiedemann) (Diptera: Tephritidae), commonly known as the sunflower maggot, is native to North America, and is a pest of Helianthus annuus (sunflower). In 2010, two females of the species were recorded on a young sunflower in Treptow-köpenick, a borough of Berlin, Germany. This was the first record of the species in Europe and was followed by three more records of the fly in Wartenberg, Lankwitz and Tempelhof, also boroughs of Berlin, in the same year. In view of these findings and the importance of sunflower cultivation in Europe, Strauzia longipennis was added to the EPPO Alert List in 2011. The fly was subsequently recorded in urban areas of Berlin and in fields of Land Brandenburg in 2011 and 2012, confirming its establishment in Germany. Given its native climate and the range of its host, there is potential for this fly to spread throughout Europe and into the UK. Geographical Distribution Strauzia longipennis is widespread in its native range of the USA and Canada. It is now also present in Germany, probably from as early as 2008. Host Plants The fly’s primary host is H. annuus (sunflower). It has also been observed on other Helianthus species, such as H. maximilianii (maximilian sunflower) and H. tuberosus (Jerusalem artichoke), and on species of the Asteraceae family, including Ageratina altissima (white snakeroot), Ambrosia trifida (Giant ragweed), and Smallanthus uvedalia. Description The eggs are around 1 mm in length and are white, with an elongated shape. -

Understanding the pest pressures unique to this region is crucial in producing a viable crop. Surveys of sunflower fields in the Northeast have shown that though plant populations are similar to the national averages, estimated yields are lower, primarily due to pest issues. Entire sunflower fields have been lost to pest pressures such as birds, weeds, insects, and disease, but Integrated Pest Management (IPM) strategies can help sunflower growers mitigate these problems. To determine when problematic insects emerge in Vermont, and how prevalent they are across the state, traps were installed and monitored across the state for banded sunflower moth and sunflower maggot species. -
E1457 Integrated Pest Management of Sunflower Insect Pests in The
E1457 Integrated Pest Management of Sunflower Insect Pests in the Northern Great Plains Janet J. Knodel, Extension Entomologist Department of Entomology, North Dakota State University, Fargo, ND Laurence D. Charlet, Research Entomologist USDA, ARS, Northern Crop Science Laboratory, Fargo, ND John Gavloski, Extension Entomologist Manitoba Agriculture, Food and Rural Initiatives, Crops Branch, Carman, MB ultivated sunflowers, Helianthus annuus L., are native to North America and include 50 species in the genus Helianthus. Because sunflowers are Cnative, associated insects have coevolved with the plants for centuries. When sunflowers were altered from a wild to a cultivated state, the changes had an impact on the insects associated with sunflowers in their native home. Plant architecture, growth phenology and plant community were altered when sunflowers were changed from wild to cultivated. For plant architecture, sunflowers changed from multiple to a single head, from branched to a single stem and from small to large seeds. The growth phenology also changed from variable emergence and extended periods of flowering in the wild type sunflower to discrete emergence and a short flowering period in cultivated sunflower. The plant community changed from small patches of mixed species of wild sunflowers to large acreage of a monoculture of cultivated sunflowers. A number of insects made the transition from the wild plant type to the cultivated plant to feed and develop. Some of these species affect the producers’ ability to increase seed production and thus have become economic pests. In the major sunflower-producing areas of the Dakotas, Minnesota and Manitoba, approximately 15 species of insects can cause plant injury and economic loss to sunflowers, depending on the severity of infestation. -

Received: 11 August 2019 ; Accepted: 23 September 2019 ; Published: 1 October 2019 Abstract: This work introduces a new approach for automatic identification of crickets, katydids and cicadas analyzing their acoustic signals. We propose the building of a tool to identify this biodiversity. The study proposes a sound parameterization technique designed specifically for identification and classification of acoustic signals of insects using Mel Frequency Cepstral Coefficients (MFCC) and Linear Frequency Cepstral Coefficients (LFCC). These two sets of coefficients are evaluated individually as has been done in previous studies and have been compared with the fusion proposed in this work, showing an outstanding increase in identification and classification at species level reaching a success rate of 98.07% on 343 insect species.
