Abstract

Plutella xylostella is one of the main pests of cabbage plants which can reduce
productivity and yield quality by up to 58 – 100%. The use of
entomopathogenic fungi in field control is still limited by less supportive
environmental conditions that inhibit conidial production and reduce its
pathogenic levels. This study aimed to identify the effect of the application of
entomopathogenic fungi L. lecanii and B. bassiana with the addition of castor
and neem seed oil in controlling P. xylostella, determine the best combination
of entomopathogenic fungi L. lecanii and B. bassiana with plant oil in
controlling P. xylostella. The research was carried out at the Plant Protection
Laboratory, Faculty of Agriculture, Universitas Pembangunan Nasional
"Veteran" Yogyakarta from May to August 2023. The method used is a one�factor Completely Randomized Design (CRD), in 9 treatments and 3
replications. Parameters observed included conidia viability (%), mortality of
P. xylostella larvae, percentage of pupae and imago formed (%), time required
to pupate (days), time required to become an imago (days), and inhibition of
feeding activity (%). The data obtained were analysed using ANOVA and to
determine differences between treatments an Orthogonal Contrast test was
performed with a significance level of 5%. Based on research, adding plant oil
to the application of entomopathogenic fungi L. lecanii and B. bassiana has no
effect on mortality and pupa formed of P. xylostella, but does affect to suppress
the development of imago formed and influence the eating ability. The
combination of L. lecanii and B. bassiana with each plant oil gave equally good
results in increasing the mortality of P. xylostella larvae, inhibiting the
development of pupae and imago, and reducing the ability to eat. The
combination of L. lecanii with neem oil tends to suppress the development of
P. xylostella imago, while the combination of B. bassiana with neem seed oil
is able to influence the eating ability of P. xylostella.
