Development and application of molecular gut-content analysis to detect aphid and coccinellid predation by Harmonia axyridis （Coleoptera： Coccinellidae）in Italy

Insect Science 2015年第6期22卷 719-730页

作者： Gabriele Rondoni Kacie j. Athey james D. Harwood Eric Contit Carlo Ricci john j. obrycki Department of Agricultural Food and Environmental Sciences University of Perugia Borgo XX Giugno 74 Perugia 06121 Italy and Department of Entomology University of Kentucky S-225 Agricultural Science Center North Lexington KY 40546-0091 USA

Despite their positive effect in reducing pest populations, exotic generalist predators sometimes become invasive and contribute to the displacement of indigenous species in the same trophic level. Although laboratory experiments have linked intraguild predation （IGP） to these interactions, field evidence and quantification of IGP are still lacking for most systems. The recent establishment of the exotic Harmonia axyridis （Pallas）（Coleoptera： Coccinellidae） in Italy raises concern about the detrimental effect that the ladybird could have on native coccinellids. Here we assessed, under laboratory conditions, the acceptability and suitability of eggs of 2 native ladybirds, Adalia bipunctata L. and Oenopia conglobata （L.）, as prey items for H. axyridis larvae. Then we developed primers for molecular gut-content analysis to detect predation by H. axyridis on the 2 ladybirds and on the aphid Eucallipterus tiliae L. Species-specific 16S primers were developed for the 3 species and laboratory feeding trials were conducted to quantify the rate of prey DNA breakdown in the gut of//. axyridis. Moreover, to field evaluate primers, H. axyridis 4th instars （n = 132） were systematically collected from linden trees in northern Italy and screened for the presence of prey DNA. Seventy-three percent and 7% of field collected H. axyridis were positive for aphid and coccinellid DNA, respectively. Predation upon aphid and A. bipunctata was lower than predicted if density dependent consumption was expected, while predation upon O. conglobata was significantly higher. Here, we provided the first evidence of IGP among feral populations ofH. axyridis and indigenous ladybird beetles, occurring in Italy.

Co-Located Battery Energy Storage Optimisation for Dynamic Containment Under the UK Frequency Response Market Reforms

引用

CSEE journal of Power and Energy Systems 2025年第1期11卷 340-351页

作者： Fulin Fan john Nwobu David Campos-Gaona Department of Electronic and Electrical Engineering University of StrathclydeGlasgowG11XWU.K Offshore Renewable Energy Catapult GlasgowG11RDU.K.

Accelerated development of battery technologies heightens an interest in co-locating battery energy storage systems (BESSs) with renewable power plants for stacking of multiple revenue streams such as frequency response services to AC grids. Frequency response market reforms in the UK introduce new end-state services and require evaluating techno-economic feasibility of co-location projects in new circumstances. This paper develops a BESS optimisation method to optimize capacity and operating strategy of a co-located BESS for providing latest Dynamic Containment (DC) services based on the UK perspective. BESS optimisation method simulates BESS delivering DC responses and following operational baselines for state of energy (SoE) restoration, as well as, coordinating with its co-located power plant. Then net present value of BESS co-location project is estimated from power flows across the system and maximised to suggest optimal BESS capacity, target energy footroom and/or headroom levels for baseline estimation, and possible SoE ranges suitable for energy interchange with its co-located power plant. BESS optimisation method is tested based on a particular transmission-level wind farm in the UK and discussed alongside operation and profitability of a BESS co-location project under frequency response market reforms.
