Abstract:abstract. Establishing continuous and reliable colonies of pestparasitoid systems in the laboratory is an essential requirement for carrying out manipulative experiments on biological control. Here we describe in detail the rearing protocols that we optimized for the efficient rearing of the cabbage moth Mamestra brassicae and its key parasitoid Microplitis mediator.
“…Flowering plants found in Tlekung Village have a variety of aromas, the aroma of flowers is also an attraction as well as a sign of plant species identification for insects. It is likely that the compounds found also function as signals to attract pollinating butterflies, and mean the arrival of the parasitoid Microplitus mediator [15]. The largest number of plant species found was the Asteraceae family with 1963 individuals, followed by Cyperaceae with 142 individuals, Poaceae with 94 individuals, Malvaceae with 64 individuals, and Myrtaceae with 45 individuals (Figure 2).…”

This study aims to identify plant species and analyze the density (D), frequency (F), Importance Value Index (IVI) of each plant that is a source of food for Apis sp. and Trigona sp. in Tlekung Village. This research was conducted using survey and sampling methods in 3 garden locations where there is honey bee cultivation. Each location has 10 plots, one plot has an area of 1m x 1m. Data analysis using RD, RF, and IVI formulas. The results of the study were 2579 individuals consisting of 37 species from 20 families and 18 orders. The plant species that has the largest IVI is Synedrella nodiflora (66.30) from the family Asteraceae order Asterales as well as recommendations to be provided around the garden to support the feed of Apis sp. and Trigona sp.

“…Large-scale parasitoid rearing is an important factor in biological control [9,10]. Many factors can influence the success of parasitoid rearing including microclimate compatibility, appropriate feed [7,11], absence of pathogens or other natural enemies, and the absence of superparasitism [12].…”
A good rearing method is one of the keys in successful biological control practices. This also applied on biological control of Spodoptera litura Fabricius (Lepidoptera: Noctuidae). The objective of this study is to observe the development of Microplitis (Snellanius) manilae (Hymenoptera: Braconidae) on S. litura which cultured in the natural diet (host plants) and the artificial diet. This study was conducted with two treatments which were larvae of S. litura fed with natural diet and artificial diet. Each treatment has 10 individuals as replicates. Each larva was placed in a different petri dish along with the adult of M. manilae. The larvae were exposed to adult parasitoids of M. manilae for 24 hr. Then, the larvae were reared until the parasitoid emerged. The results showed that the highest number of parasitization was found in the hosts which were fed on an artificial diet. Whereas, the highest number of parasitoids emerged were found from the hosts which provided with a natural diet. On both diets, more female parasitoids emerged than males. The difference in nutrient content given to host larvae plays a major role in affecting the number of hosts parasitization, the number of emerged parasitoids and the sex ratio of parasitoids.
