Fitness of two mushroom flies Bradysia minpleuroti (Diptera: Sciaridae) and Coboldia fuscipes (Diptera: Scatopsidae) fed on two edible mushrooms

<a name="OLE_LINK220"></a><a name="OLE_LINK189"></a>Dictyophora rubrovolvata and <a name="OLE_LINK87"></a>Pleurotus ostreatus are economically important mushrooms in China. <a name="_Hlk146231531"></a>Bradysia minpleuroti Yang et Zhang and <a name="OLE_LINK71"></a>Cobolidia fuscipes (Meigen, 1830) are important mushroom flies that damage the two mushrooms. In this study we used the age-stage, two-sex life table method assessed <a name="_Hlk146230932"></a>the fitness of <a name="_Hlk143696432"></a>B. minpleuroti and C. fuscipes when they were respectively fed on <a name="OLE_LINK20"></a>D. rubrovolvata and P. ostreatus. Our results showed that the 1st (2.39 days) and 2nd (1.41 days) instar larvae, pupa (2.87 days) and total longevity (18.19 days) of B. minpleuroti were shorter when fed on P. ostreatus than fed on D. rubrovolvata (3.46, 1.86, 3.10, 20.19 days). <a name="OLE_LINK233"></a>B. minpleuroti had similar fecundity when fed on the two edible mushrooms. B. minpleuroti had higher values of net reproductive rate (R0, 87.73), intrinsic rate of increase (r, 0.2604), and finite rate of increase (λ, 1.2974) and shorter mean generation time (T, 17.19) when fed on P. ostreatus than fed on D. rubrovalvata. The developmental period of larvae stage and pupa stage of C. fuscipes were significantly affected by the two edible mushrooms. Female fecundity, total longevity, R0, r, λ and T of C. fuscipes were not significantly different between the two edible mushrooms. We found that<a name="OLE_LINK174"></a> fitness of B. minpleuroti larvae had higher fitness when fed on P. ostreatus than fed on D. rubrovolvata. However, <a name="OLE_LINK183"></a>the fitness of C. fuscipes larvae had no significant difference fed on the two edible mushrooms. This study has provided valuable data and insights by delving into the adaptability of two significant pests on two edible mushrooms. It facilitates the development of more effective pest management strategies, contributing to the development of the mushroom industry.

Effects of the entomopathogenic fungus Mucor hiemalis BO-1 on the physical functions and transcriptional signatures of Bradysia odoriphaga larvae

Mucor hiemalis BO-1 is an entomopathogenic fungus that infects Bradysia odoriphaga, a destructive root maggot. M. hiemalis BO-1 possesses stronger pathogenicity to the larvae than to other stages of B. odoriphaga and provides satisfactory field control. However, the physiological response of B. odoriphaga larvae to infection and the infection mechanism of M. hiemalis are unknown. We detected some physiological indicators of diseased B. odoriphaga larvae infected by M. hiemalis BO-1. These included changes in consumption, nutrient contents and digestive and antioxidant enzymes. We performed transcriptome analysis of diseased B. odoriphaga larvae and found that M. hiemalis BO-1 showed acute toxicity to B. odoriphaga larvae and was as toxic as some chemical pesticides. The food consumption of diseased B. odoriphaga after inoculation with M. hiemalis spores decreased significantly, and there was a significant decrease in total protein, lipid and carbohydrates in diseased larvae. Key digestive enzymes (protease, α-amylase, lipase and cellulase) were significantly inhibited during infection. Peroxidase maintained high activity, and the activity of other antioxidant enzymes (catalase, superoxide dismutase and glutathione S-transferases) first increased and then decreased. Combined with the transcriptional signatures of diseased B. odoriphaga larvae, M. hiemalis BO-1 infection resulted in decreased food consumption, reduced digestive enzyme activity and altered energy metabolism and material accumulation. Infection was also accompanied by fluctuations in immune function, such as cytochrome P450 and the Toll pathway. Therefore, our results laid a basis for the further study of the interactions between M. hiemalis BO-1 and B. odoriphaga and promoted the genetic improvement of entomopathogenic fungi.
