“…Of note, some authors observed a detrimental effect of treatments involving entomopathogenic nematodes on mushroom mycelia, such as reduced yield in early flushes, depending on the nematode dosage rate [88]. Meanwhile, the effectiveness of a single biocontrol agent can be restricted by biological characteristics of prey species, and therefore the application of a combined treatment can improve control efficacy [87,115]. Navarro and Gea [86], assaying a combined nematode treatment (0.5 × 10 6 IJm −2 S. feltiae + 0.5 × 10 6 IJm −2 S. carpocapsae) against mushroom flies reported no adverse effect on mushroom production, but no reduction in M. halterata populations was noted.…”

“…This species kills more fly larvae than it can eat, and it has a preference for live prey [92]. Meanwhile, the effectiveness of the predatory mites could be restricted by temperature as well as by the body size of the pest species [115]. The use of a combined treatment of biocontrol agents could improve control efficacy toward several pest species in comparison with treatment using a single biocontrol agent.…”

Diptera are among the most serious arthropod pests affecting mushroom crops. Phorid flies, especially Megaselia halterata, have traditionally been globally considered as a minor pest, although they are a very important problem on Spanish mushroom farms. The concerns with respect to the phorid fly populations have recently increased, notably jumping from being a minor to major pest in India, UK and the USA, where yield losses ranging between 10 and 40% were reported. This review updates and summarizes the available literature regarding mushroom phorid populations, stressing the natural distribution of phorids and their seasonal distribution, their biology within the growing substrates and the initial sources of infestation on mushroom farms. Moreover, the review also highlights the scarce available tools for their control and the current alternatives to chemical products.

“…To date, the pathogenicity of EPN species has been studied against a variety of insect pests of agricultural importance under controlled conditions and promising results have been reported (Karabörklü et al, 2015;Yuksel and Canhilal, 2018;Acharya et al, 2019;Mokrini et al, 2020;Öğretmen et al, 2020;Özdemir et al, 2021). However field studies on the efficacy of EPNs against many agricultural pests are still limited and the performance of EPNs in field conditions may vary remarkably as compared to laboratory bioassays.…”

“…Entomopathogenic nematodes are soil adapted organisms and capable of infecting pests that live in cryptic habitats with the active host-seeking ability of IJs (Lacey and Georgis, 2012). EPNs may also provide long-term control especially for those pests in the soil environment by settling into the application area and keep the pest population naturally below the economic threshold hazard levels depending on the environmental conditions (Poinar and Grewal, 2012;Azizoglu et al, 2016;Acharya et al, 2019;Mokrini et al, 2020). The laboratory efficacy of EPNs is an important phase of pathogenicity screening studies and is well studied by many researchers around the world (Azizoglu et al, 2016;Özdemir and Evlice, 2020;Acharya et al, 2020;Mokrini et al, 2020).…”

The ground beetles, Zabrus spp. Clairville, 1806 (Coleoptera: Carabidae) is one of the major pests of wheat plants across the world, and the control of this pest is a challenging issue. In the present study, the control potential of two local entomopathogenic nematode (EPN) species [Heterorhabditis bacteriophora Poinar, 1976 (Rhabditida: Heterorhabditidae) and Steinernema feltiae Filipjev, 1934 (Rhabditida: Steinernematidae)] against the larvae of Zabrus spp. was evaluated with two trials under field conditions in 2015. EPNs were applied at the concentration of 1 x 10 6 IJs m -2 to the soil surface in mid-April and the number of alive larvae was assessed 14 days after treatment (AT). In addition, Zabrus spp.damaged wheat plants were counted to establish the efficacy of EPNs on the larvae of Zabrus spp. in short (14 days AT) and long term (6 months AT). EPNs reduced the number of alive Zabrus spp. larvae by at least 50% as compared to the control treatments in both trials. Altgough there was a remarkable decrease in the number of Zabrus spp.-damaged wheat plants to which EPNs were applied, this decrease did not produce a significant effect. Present findings indicate that EPNs tested have a good potential for sustainable management of Zabrus spp.

“…Biocontrol strategy using natural enemies of fungus gnats, such as entomopathogenic nematodes (Acharya et al, 2019;Shamshad et al, 2008;Zhang & Sanderson, 1993), the entomopathogen Bacillus thuringiensis Berliner (Osborne et al, 1985;Taylor et al, 2007), and the predatory rove beetle Dalotia coriaria Kraatz, have been assessed under laboratory conditions and explored in pest management programs for greenhouse crops (Carney et al, 2002;Echegaray et al, 2015;Katumanyane et al, 2018). However, these measures have not been sufficiently effective or field applicable in terms of reducing the economic loss caused by fungus gnats.…”

The fungus gnat Bradysia impatiens (Johannsen) is a worldwide pest inhabiting organicrich environments, including mushroom-cultivation substrates, which leads to massive production losses of edible mushrooms. To promote a non-insecticidal pest control strategy, we evaluated adult behavioural response towards two saprophytic fungal strains Aspergillus flavus Link and Mucor circinelloides Tiegh., isolated from B. impatiensinhabiting substrates and six edible mushrooms species. Our results indicated that (a) B. impatiens was most attracted to the oyster mushroom Pleurotus ostreatus among all six edible mushrooms; (b) males and females demonstrated a significant attraction for M. circinelloides over A. flavus and P. ostreatus; (c) adults demonstrated dynamic attraction tendencies that varied with the culture periods of A. flavus and M. circinelloides, wherein females represented most (mean = 78.6%) of the attracted individuals; and (d) larvae that fed on mycelial cultures of M. circinelloides could complete their entire life cycles, but larvae could not survive on a non-fungal or A. flavus diet. These results demonstrate the potential for the development of M. circinelloides in a push-pull strategy to biocontrol this pest in edible mushroom cultivation.
