KETERTARIKAN Trichogramma sp. PADA Brassica rapa L. YANG DIINOKULASIKAN Metarhizium anisopliae, TELUR, DAN LARVA Plutella xylostella (Lepidoptera: Yponomeutidae)
Plutella xylostella is a pest insect that causes the most damage to plants in the Brassicaceae family, with losses reaching up to US$4–5 billion. This study aimed to examine the attraction of parasitoids to pakchoi that had been induced with the entomopathogenic fungus Metarhizium anisopliae, eggs, and larvae of P. xylostella, and whether these treatments could attract Trichogramma sp. parasitoids. The study was used four seed treatments: for the first treatment seeds were induced with M. anisopliae through seed soaking; the second, fungal treatment seeds were provided with eggs of P. xylostella the third fungal treatment seeds eaten by P. xylostella larvae; and the control consisted of seed without fungal induction or just submerged with steril water.The results showed that Trichogramma sp. adults were more attracted to pakchoi induced with the fungus without any additional treatments, such as egg oviposition or larval feeding. The findings indicate that pakchoi colonized by endophytic fungi was chosen by the parasitoid. The combination of pakchoi and colonized by M. anisopliae provided stimuli that influence parasitoid habitat selection. Finally, Trichogramma sp. parasitoids are more attracted to pakchoi induced only with M. anisopliae. These plants have the potential to act as attractants for Trichogramma sp.
