The host was identified initially as a leaf-cutting ant (Atta cephalotes, Camponotus sericeiventris Attini, Myrmicinae). However, a critical examination of the original illustration reveals that the host is the golden carpenter ants carpenter ant, Camponotus sericeiventris (Camponotini, Formicinae). Because the holotype is no longer extant and epitype the original diagnosis lacks critical taxonomic information – specifically, on ascus and ascospore morphology – a new Ophiocordyceps type from Minas Gerais State of south-east Brazil is designated herein. A re-description of the fungus is provided and phylogeny a new phylogenetic tree of the O. unilateralis clade is presented. It is predicted that many more species of zombie- ant fungi remain to be delimited within the O. unilateralis complex worldwide, on ants of the tribe Camponotini. Published online: 15 December 2017.

Here, we describe three newly discovered host-specific species, Ophiocordyceps camponoti-atricipis, O. camponoti- bispinosi and O. camponoti-indiani, on Camponotus ants from the central Amazonian region of Brazil, which can readily be separated using morphological traits, in particular the shape and behavior of the ascospores. DNA sequence data support inclusion of these species within the Ophiocordyceps unilateralis complex. Introduction In tropical forests, social insects (ants, bees, termites and wasps) are the most abundant land-dwelling arthropods. -

Further Screening of Entomopathogenic Fungi and Nematodes As Control Agents for Drosophila Suzukii
insects Article Further Screening of Entomopathogenic Fungi and Nematodes as Control Agents for Drosophila suzukii Andrew G. S. Cuthbertson * and Neil Audsley Fera, Sand Hutton, York YO41 1LZ, UK; [email protected] * Correspondence: [email protected]; Tel.: +44-1904-462-201 Academic Editor: Brian T. Forschler Received: 15 March 2016; Accepted: 6 June 2016; Published: 9 June 2016 Abstract: Drosophila suzukii populations remain low in the UK. To date, there have been no reports of widespread damage. Previous research demonstrated that various species of entomopathogenic fungi and nematodes could potentially suppress D. suzukii population development under laboratory trials. However, none of the given species was concluded to be specifically efficient in suppressing D. suzukii. Therefore, there is a need to screen further species to determine their efficacy. The following entomopathogenic agents were evaluated for their potential to act as control agents for D. suzukii: Metarhizium anisopliae; Isaria fumosorosea; a non-commercial coded fungal product (Coded B); Steinernema feltiae, S. carpocapsae, S. kraussei and Heterorhabditis bacteriophora. The fungi were screened for efficacy against the fly on fruit while the nematodes were evaluated for the potential to be applied as soil drenches targeting larvae and pupal life-stages. All three fungi species screened reduced D. suzukii populations developing from infested berries. Isaria fumosorosea significantly (p < 0.001) reduced population development of D. suzukii from infested berries. All nematodes significantly reduced adult emergence from pupal cases compared to the water control. Larvae proved more susceptible to nematode infection. Heterorhabditis bacteriophora proved the best from the four nematodes investigated; readily emerging from punctured larvae and causing 95% mortality. -

In the first method, conidial suspensions (1 × 106 and 1 × 108 conidia ml−1) of the fungus were directly applied to the beetles in Petri dishes (2 ml per dish), using a Potter spray tower. In the second method, the same conidial suspensions were applied 8 −1 on a sterile hazelnut branch placed in the Petri dishes. The LT50 and LT90 values of 1 × 10 conidia ml were 4.78 and 5.94/days, for A. dispar in the direct application method, while they were 4.76 and 6.49/days in the branch application 8 −1 method. Similarly, LT50 and LT90 values of 1 × 10 conidia ml for X. germanus were 4.18 and 5.62/days, and 5.11 and 7.89/days, for the direct and branch application methods, respectively. The efficiency of 1 × 106 conidia ml−1 was lower than that of 1 × 108 against the beetles in both application methods. -

Ophicordyceps sp. holds insects. In this paper we report for the first time the immense potential to be used as a biological pest control occurrence of Ophicordyceps nutans Pat. a species agent (Sasaki et al. 2008; Friedrich et al. 2018). There are belonging to this entomopathogenic fungi group in Kanger several species of Ophicordyceps fungi (Ophicordyceps Valley National Park in Bastar District of Chhattisgarh in sinensis, O. forquignonii, O. gracilis, O. militaris, O. Central India. The fruiting body or ascocarp of O. nutans coccinea, etc.) having different medicinal properties was found in Halyomorpha halys, brown marmorated stink (Sasaki et al. 2005). In China, Ophicordyceps sp. is tradi- bug—an insect pest. The study highlighted the impact of O. tionally used as medicine in a number of diseases (Hywel- nutans on the host insect and the damage it causes in trees Jones 1995).

Lopez-Llorca Received: 9 December 2015; Accepted: 29 January 2016; Published: 5 February 2016 Abstract: The nematophagous and entomogenous fungi are natural enemies of nematodes and insects and have been utilized by humans to control agricultural and forestry pests. Some of these fungi have been or are being developed as biological control agents in China and worldwide. Several important nematophagous and entomogenous fungi, including nematode-trapping fungi (Arthrobotrys oligospora and Drechslerella stenobrocha), nematode endoparasite (Hirsutella minnesotensis), insect pathogens (Beauveria bassiana and Metarhizium spp.) and Chinese medicinal fungi (Ophiocordyceps sinensis and Cordyceps militaris), have been genome sequenced and extensively analyzed in China. The biology, evolution, and pharmaceutical application of these fungi and their interacting with host nematodes and insects revealed by genomes, comparing genomes coupled with transcriptomes are summarized and reviewed in this paper. Keywords: fungal genome; biological control; nematophagous; entomogenous 1. Introduction Nematophagous fungi infect their hosts using traps and other devices such as adhesive conidia and parasitic hyphae tips [1,2]. Entomogenous fungi are associated with insects, mainly as pathogens or parasites [3]. Both nematophagous and entomogenous fungi are important biocontrol resources [1,3].
