“…Colonization of the surfaces of peat-based growing media and wet rockwool by Peziza ostracoderma has been previously reported (Meinken et al 2016). Lecanicillium (formerly Verticillium lecanii) has been recovered from a wide range of sources and is known for its mycoparasitic and entomopathogenic activity (Peciulyte and Kacergius 2012;El-Debaiky 2017). It was reported to parasitize the fruiting bodies of the white jelly-leaf mushroom Tremella fuciformis (Liu et al 2018).…”

Fusarium oxysporum causes root browning and crown infection on marijuana (Cannabis sativa L.) plants, resulting in stunted growth, yellowing of leaves, and plant death. Pathogen presence and diversity were assessed in samples of diseased crowns, stems, pith tissues and roots from five commercial production facilities in British Columbia and Ontario. PCR of the elongation factor (EF-1 α) region and sequence analysis confirmed the identity and phylogenetic relationships among 33 representative isolates from over 200 isolates collected. Stock (mother) plants of eight cannabis strains (genotypes) with symptoms of yellowing, crown rot and internal stem decay yielded F. oxysporum at a frequency of 70-100%. Cuttings obtained from asymptomatic plants showed pathogen recovery rates of 1-2% on potato dextrose agar at distances of 90-150 cm from the crowns. Symptoms of damping-off were observed on cuttings in a rooting and propagation facility. Pathogenicity tests confirmed the development of characteristic symptoms on cuttings and rooted plants inoculated with F. oxysporum. Phylogenetic analysis indicated that isolates of F. oxysporum from BC belonged to a separate clade from ON isolates and that clonal spread was occurring within licenced facilities. Air sampling conducted in a greenhouse facility revealed F. oxysporum was present in areas used for rooting, vegetative propagation, and where stock plants were grown. The pathogen was also recovered from inflorescences. These findings indicate that F. oxysporum is present in several commercial production facilities in Canada and reduces root development and establishment of rooted cuttings, and causes yellowing and stunting on flowering plants of many cannabis strains.

“…At the egg stage, mycoses were mainly caused by Cladosporus cladosporioides (30.68% of all mycoses), at the pupa stage Cordyceps fumosorosea and Beauveria bassiana prevailed (17.49% and 16.94%, respectively), and Lecanicillum aphanocladii (39.45%) prevailed at the adult stage. The latter fungus species was recorded for the first time in Lithuania, and thus its identification was checked and confirmed by application of molecular methods and published in a separate paper [48].…”

The total mortality of the leaf-miner horse-chestnut pest, Cameraria ohridella, collected in nature, and the mortality associated with mycoses were assessed under laboratory conditions in stages: for eggs mortality rates of 9.78% and 61.97% were found, respectively; for caterpillars, 45.25% and 5.59%, respectively; and for pupae 21.22% and 100%, respectively. At the egg stage, Cladosporus cladosporioides caused mycosis most often (27% of all mycoses); at the caterpillar stage there was no pronounced predominant fungus species; at the pupal stage both Cordyceps fumosorosea and Beauveria bassiana (32% and 31%, respectively) were most dominant; whereas at the adult stage Lecanicillum aphanocladii (43%) were most dominant. C. ohridella moths remained the most vulnerable during the pupal and caterpillar stages. Maximum diversity of fungi associated with the leaf-miner moth was reached during the period of development inside the chestnut leaf (Shannon–Wiener index—H′ = 2.608 at the caterpillar stage, H′ = 2.619 at the pupal stage), while the minimum was reached in the adult stage (H′ = 1.757). In the caterpillar and pupa stages, saprophytic fungi were most often recorded. Comparative laboratory tests revealed novel properties of the fungus L. aphanocladii, its effectiveness as the leaf-miner moth‘s entomopathogen and its suitability for field application trials while developing environment-friendly methods for horse-chestnut pest control.

Parasitoids and fungal pathogens of Phyllonorycter issikii (Kumata, 1963) from Bulgaria

et al. 2018

The lime leaf miner, Phyllonorycter issikii, is a moth species native to East Asia, which recently invaded considerable part of Europe. A study on the natural enemies of this invasive species was conducted in Bulgaria. Tilia cordata leaves infested with the lime leaf miner were collected in 2015 and 2016 in two public parks in Sofia. A total of eleven eulophid parasitoids (Hymenoptera: Eulophidae) belonging to three subfamilies -Entedoninae, Eulophinae and Tetrastichinae, and one braconid species (Hymenoptera: Braconidae) were recorded. In addition, one unidentified ichneumonid species was reared. Minotetrastichus platanellus was the most abundant species in the samples comprising 76.88% of the parasitoids reared from collected immature and pupal stages of Ph. issikii. It is followed by Sympiesis gordius (6.53%) and S. sericeicornis (6.03%). Three new host-parasitoid associations were established. The entomopathogenic fungi Beuveria bassiana and Metarhizium anisopliae (Hypocreales) were isolated for the first time from cadavers of Ph. issikii larvae and pupae. Based on the presented observation we hypothesized that the lime leaf miner can produce three generations in Bulgaria.
