The genus Purpureocillium, recently described and only
two species have been described for this genus: Purpureocillium
lilacinum, which was classified by Luansgna et al. (2011) and
has many biological, taxonomical and biotechnological studies; and
P. lavendulum, described by Perdomo, et al. (2013).
Purpureocillium sp. (Strain UdeA0106) is a biocontrol
agent and it’s used in the management of garden symphylians
and the nematode Meloidogyne spp. in flower
crops.
Symphyilans belongs to the subphylum Myriapoda and are a known
plague that affects different commercial crops. The use of
chemically-based pesticides to control these organisms is
ineffective and the price, both monetary and environmental, is
higher. However, studies carried out in recent years have shown
that the strain UdeA0106 is effective both in vitro and when
applied on commercial flower crops (Salazar 2015). The study of
this fungi will increment the knowledge of an organisms that
it’s applying in crops of agricultural importance in order to
avoid the use of insecticides to control pests. The information
obtained will be used for improve the actually bioformulations and
the technical recommendations for its application in the crops.
