“…The P. citrinum culture filtrate contains secondary metabolites and is toxic to insects, for example, patulin which can kill Culex quinquefasciatus larvae up to 100% (Maketon et al 2014). P. citrinum is reported to be effective in killing insect pests (Foo et al 2017;Maketon et al 2014) and mite pests (Mazid et al 2016).…”

Abstract. Herlinda S, Efendi RA, Suharjo R, Hasbi, Setiawan A, Elfita, Verawaty M. 2020. New emerging entomopathogenic fungi isolated from soil in South Sumatra (Indonesia) and their filtrate and conidial insecticidal activity against Spodoptera litura. Biodiversitas 21: 5102-5113. This study was carried out to confirm identity of Beauveria bassiana and Metarhizium anisopliae using sequence analysis of Internal Transcribed Spacer (ITS) region as well as the two unknown isolates of EPF and to investigate their filtrate and conidial insecticidal activity against S. litura larvae. The EPF species were identified based on morphological characters and molecular analysis. Their culture filtrate and conidial bioassays were performed on S. litura larvae. The species found were Penicillium citrinum (BKbTp), Talaromyces diversus (MSwTp1), B. bassiana (BSwTd4), and M. anisopliae (MSwTp3) and have been deposited in the GenBank. All EPF species have high insecticidal activity against S. litura larvae. The highest larvae mortality caused by filtrate was found on P. citrinum (98.67%) and not significantly different from those of T. diversus (96%), but significantly different from B. bassiana (86.67%) and M anisopliae (82.67%). The highest larvae mortality caused by the conidia was also occurred to P. citrinum (98.67%) which was not significantly different from those of T. diversus (97.33%), B. bassiana (86.67%), and M. anisopliae (86.67%). The LT50 caused by T. diversus filtrate was the shortest (6.19 days) and not significantly different from those caused by P. citrinum (6.62 days). The shortest LT50 caused by conidia was found on P. citrinum (5.45 days). Therefore, the conidia and filtrate of P. citrinum, a new emerging entomopathogenic fungus, has the highest insecticidal activity. P. citrinum has the potential to be developed into commercial mycoinsecticides.

“…To account for variation in the energetic resources (e.g., fat stores) available to hosts that could influence survival, we assessed each firefly for condition individually under CO 2 anaesthesia on a Flystuff Flypad (Genesee Scientific; El Cajon, CA). Briefly, to calculate condition, we measured elytron length, a measure of adult body size that reflects the resources acquired as a larva and that is not expected to change over adult lifetime (den Nijs et al, 1996;Lagisz, 2008; Supporting Information File 1-Sections I, V.S1), using a digital calliper (mm;VWR cat. 12777-830).…”

“…Larvae live on or in the soil, where they likely encounter a diverse microbial community in the substrate as well as through their earthworm prey, including bacteria in the genera Serratia and Pseudomonas (Green et al, 2021). Larvae are also susceptible to bacterial and fungal infections that impede lab culture (Fallon et al, 2018; Foo et al, 2017; McLean et al, 1972). In contrast to the larval stage, adult Photinus may only live a few weeks, with limited evidence for nutritional intake (Williams, 1917; Lloyd, 1997; but see Faust & Faust, 2014).…”

1. The degree to which host, pathogen, and environmental characteristics determine fitness outcomes in response to infection across the tree of life is a key question in ecoimmunology. Because infection experiments require large sample sizes and careful controls, studies have generally been limited to lab-adapted organisms.2. Photinus pyralis is a charismatic firefly that is abundant during its annual summer emergence in the Eastern United States. Here, we assess the importance of host condition, pathogen identity and dose, and pre-infection environment on survival outcomes in response to bacterial infection in wild-caught adult male P. pyralis.3. Although survival after sterile saline injection was not statistically different from survival of uninjected controls, survival kinetics support sterile saline injection as the most appropriate control. 4. Serratia marcescens and Providencia rettgeri infections increased mortality, especially at high doses. In contrast to fruit fly studies, Providencia sneebia, Pseudomonas aeruginosa, and Enterococcus faecalis infections did not. Infection with higher doses of P. rettgeri had an increased risk of death for fireflies caught later in the season than those captured earlier, but seasonality did not significantly interact with dose to impact mortality with any of the other bacterial species.5. These results highlight the importance of considering host, pathogen, and environmental factors when investigating infection outcomes in wild-caught, non-model systems. The differences in survival between fireflies and fruit flies emphasise that further studies in a broad array of organisms are needed to explore the diversity of infection responses across the tree of life.

“…These include entomopathogenic fungi (cf. Day, 2011;Foo, Seelan & Dawood, 2017), nematodes, and parasitoid tachinid and phorid flies (Lloyd, 1973;Faust, 2017). Interestingly, but consistent with their mostly diurnal behavior, parasitic wasps were never reported to parasitize firefly larvae.…”

Background Fireflies (Coleoptera: Lampyridae) are commonly recognized by adult traits, such as a soft exoskeleton, lanterns and associated glow and flash patterns, but their larval stage is far less appreciated. However, fireflies spend most of their lives as larvae, and adults of most species rely solely on resources previously obtained. Therefore, studying the immature stages is imperative towards a comprehensive understanding of fireflies. This paper reviews and indicates key gaps in the biology of firefly larvae based on available literature. Methodology We reviewed the literature on firefly larvae to identify key issues and important taxonomic, geographic, and subject biases and gaps. Results We found 376 papers that included information on firefly larvae. Only 139 species in 47 genera across eight of eleven lampyrid subfamilies have been studied during larval stages. These numbers reveal a staggering gap, since 94% of species and over half of the genera of fireflies were never studied in a crucial stage of their life cycle. Most studies on firefly larvae focus on two subfamilies (Luciolinae and Lampyrinae) in four zoogeographic regions (Sino-Japanese, Oriental, Nearctic, and Palearctic), whereas the other subfamilies and regions remain largely unstudied. These studies mainly dealt with morphology and behavior, other subjects remaining greatly understudied by comparison, including habitats, life cycle, physiology and interactions. Conclusions Together, these literature biases and gaps highlight how little is known about firefly larvae, and warmly invite basic and applied research, in the field and in the lab, to overcome these limitations and improve our understanding of firefly biology to better preserve them.
