“…These insects feed on the roots of the seedlings causing lodging, mortality, yield losses (Reddy et al, 2014;Furlan et al, 2017), and resulting in significant economic issues across several European countries (Benjamin et al, 2018). Due to their belowground life cycle, overlapping generations, polyphagous nature, and their adaption to a wide range of agricultural ecosystems (Furlan, 1998(Furlan, , 2005Ritter and Richter, 2013;Sufyan et al, 2014;Traugott et al, 2013Traugott et al, , 2015, wireworms are difficult to control, especially in organic farming, where persistent, non-specific soil insecticides cannot be used. As a result of these regulatory changes on the utilization of chemical pesticides, the need for biological products have increased (Schepl and Paffrath, 2007;Brandl et al, 2016;Benjamin et al, 2018).…”

Agriotes spp. larvae, commonly known as wireworms, are major pests that cause great economic damage to many European crops. To combat them, most farmers prophylactically apply soil insecticides, including high-impact ones such as neonicotinoids. However, due to their hidden life cycle below ground, wireworms are difficult to control, especially in organic farming where persistent, non-specific soil insecticides cannot be used. As legislation tightens regulation on chemical insecticides that have harmful effects on humans and the environment (such as the withdrawal of many chemicals and the general limitation of all of them), biological control agents are gaining attention as an alternative strategy. The aim of this study was to investigate the agronomic effectiveness of Spinosad, a bioinsecticide, in row application during planting to manage wireworms in maize (Zea mays) in Northern Italy. Based on the performance of Spinosad, even in harsh conditions as observed throughout this study, and its ability to mitigate yield losses compared to the non-treated control, we conclude that this product can be used as part of an Integrated Pest Management to mitigate the damages caused by this pest in organic agriculture. However, further studies are required to better understand how this bioinsecticide can be integrated into Agriotes spp management to reduce economic losses and have a positive impact on the environment and public health

“…They feed on the roots, shoots, tubers and bulbs of many arable and vegetable crops, including maize and other cereals, potatoes and carrots (reviewed in Parker and Howard 2001;Ritter and Richter 2013;Traugott et al 2015). In many of these crops, wireworms are not necessarily the most destructive insects, but are among the most difficult to control, particularly because of their long life cycle and overlapping generations, their polyphagous nature and their adaption to a wide range of agricultural ecosystems, including grassland and arable crops (Furlan 1998;Ritter and Richter 2013;Sonnemann et al 2014;Sufyan et al 2014;Traugott et al 2013Traugott et al , 2015. Wireworms are also able to react quickly to changes in abiotic conditions with vertical migration to depths of 50 cm or more (Fisher et al 1975;Furlan 1998Furlan , 2004Schaerffenberg 1942).…”

Preventive application of an entomopathogenic fungus in cover crops for wireworm control

et al. 2017

Efficacy of the Metarhizium brunneum Petch (Hypocreales: Clavicipitaceae) strain ART2825 for control of wireworms (Agriotes obscurus (L.), Coleoptera: Elateridae) was examined in a semi-field pot experiment. Pots were treated in late summer during sowing of spring oat as a cover crop. Survival of wireworms was assessed four weeks after their release in October 2013, and 30 weeks after release in April 2014. Viability and persistence of the fungus was determined by counting colony forming units from substrate samples and microsatellite analyses of recovered Metarhizium isolates. The number of colonies detected in the substrate in October 2013 increased with increasing concentrations of applied conidia, and no significant reduction was observed at the second evaluation date in April 2014. Increasing conidia application rates significantly increased mycosis and reduced wireworm survival, to a level comparable to that of treatment using insecticide-coated oat seeds. The preventive application of M. brunneum conidia to reduce wireworm populations in cover crops, preceding a damage-sensitive crop like potatoes, may be a promising biocontrol strategy.

“…

Certain click beetle larvae have gained recognition for their capacity to inflict damage on the underground parts of cultivated plants (Traugott et al, 2013), making them a formidable pest to be effectively controlled in agroecosystems (Nikoukar & Rashed, 2022). Traditionally, the management of these larvae has relied heavily on the use of persistent soil insecticides, particularly organophosphorous compounds, although their environmental suitability has been questioned recently (Furlan et al, 2010).

Harnessing the potential of Citrus natsudaidai: An attractant for Melanotus senilis larvae

Click beetle larvae have been observed to cause crop damage in various regions worldwide; however, accurate prediction of plant damage is hindered by their subterranean life cycle and the associated challenges in sampling. Melanotus senilis, a beetle belonging to the subfamily Elaterinae (tribe Melanotini) within the family Elateridae, is a destructive agricultural pest that harms maize, hops, and ginger. Our study presents novel evidence indicating the attraction of M. senilis larvae to Citrus natsudaidai (Japanese name “Natsumikan” or “Natsudaidai”). Through a field experiment involving different citrus fruits, namely natsumikan, oranges, and grapefruits, we found that C. natsudaidai attracted the highest number of M. senilis larvae. Furthermore, in a separate experiment in which C. natsudaidai and potatoes were placed in the field, C. natsudaidai significantly outperformed potatoes in attracting M. senilis larvae. These findings suggest that C. natsudaidai fruit placed on the soil surface attracts M. senilis larvae. C. natsudaidai fruits used in this study were sourced from those that remained unharvested until August. Therefore, it is possible that the C. natsudaidai fruits used for comparison were more mature than the citrus fruits used in this study. It is possible that the ripening of C. natsudaidai may have led to changes in CO2 and ethylene emissions, potentially attracting a greater number of M. senilis larvae. Further research is required to explore these aspects in detail.
