Paecilomyces lilacinus and P.variotii as a predator of nematode and trematode eggs

Abstract

Paecilomyces lilacinus and P.variotii are molds that can control the parasitic worms for animals and plants. The molds have been used as biological control of plant nematodes and more commercialized, but for controlling animal trematode worm parasite has not been known. For the purposes of the experiments were tested in vitro the ability local isolates of P.lilacinus and P.variotii to reduce (predator) worm eggs of Meloidogyne sp and Fasciola gigantica. The tests carried out on the eggs of the two types of worms, by adding some eggs on P. lilacinus and P.variotii spores that have been inoculated in a petri dish. The experiments were performed during a specific time with the addition of isolates for a comparison test. The result of the test from this experiment was P. lilacinus is better than P. variotii to reduce types of those worms.

Efficacy of Purpureocillium lilacinum AUMC 10149 as biocontrol agent against root-knot nematode Meloidogyne incognita infecting tomato plant

“…In vitro, the use of P. lilacinum gave maximum mortality percentage of 97.6% for second stage of M. incognita (J2) after 72 h and suppressed egg hatching with percentage of 79.8% after the same period. These results are compatible with Ahmad et al (2019) who tested the ability of local isolates of Purpureocillium to reduce the nematode eggs hatching of Meloidogyne spp. They discovered that the isolate P. lilacinum has the greatest potential destruction of nematodes eggs by 67.9%.…”

Paecilomyces and Its Importance in the Biological Control of Agricultural Pests and Diseases

“…As shown in Table 2 , P. lilacinus is the most important nematophagous fungus, as it is capable of controlling various nematode species in different crops, though other species such as P. marquandii (Massee) S. Hughes [ 170 , 171 , 172 ] or P. variotii [ 173 ] can be equally effective. Reports by Chen et al [ 171 ] on the use of P. marquandii against M. hapla showed an increase in lettuce weight, a decrease in gall formation by 25.7% and a reduction in egg production by 46.3%.…”

Paecilomyces variotii as A Plant-Growth Promoter in Horticulture

“…Among them, Byssochlamys spectabilis (Udagawa and Shoji Suzuki) Houbraken and Samson, formerly known as Paecilomyces variotii Bainier, is an ascomycete characterized by its ability to produce secondary metabolites, which belong to different chemical groups with wide biological activity [2][3][4][5]. This species has been described as a biological control agent (BCA) against nematodes [6,7], trematode eggs [8] and phytopathogenic fungi, such as Biscogniauxia mediterranea, Fusarium moniliforme and Phytophthora cinnamomi [9], Pyricularia oryzae [10], Fusarium graminearum [11] and Magnaphorte oryzae [12], among others, that function through their raw extracts, secondary bioactive metabolites or their mycelia. P. variotii produces metabolites with herbicidal [13] and insecticidal [14] activity and has been reported to control infections caused by pathogenic bacteria in fish [15] and humans [9].…”
