During the field survey, we have identified nine species of predators against this new invasive pest. These predators are naturally available in RSW affected coconut gardens and also in other host plants. Incidentally, we noticed a parasitoid for RSW from the Aphelinidae family, Encarsia guadeloupae. These entomophagous insects may provide an additional opportunity to the Coconut growing farmers of Tamil Nadu to utilize these potential biocontrol agents against invasive RSW. In this mass culturing process of these predators , we find some small tiny parasitoids emerging from pupal cocoons instead of M. desjardinsi adults and roaming inside the mass culturing cage of M. desjardinsi. The parasitoid was collected, and the collected parasitoids were studied in Central Integrated Pest Management Center, Directorate of Plant Protection Quarantine and Storage, Tiruchirappalli, Tamil Nadu. The analysis revealed that the tiny insects belonged to family Encyrtidae and Ichneumonidae, and both are pupal parasitoids of Neuropteran predator (Hayat, 2006). The ichneumonid parasitoid, Dicrogaster sp., was already reported on the Neuropteran predator. In Encyrtid parasitoid, Copidosomyia ambiguous (Subba Rao) (Hymenoptera: Chalcidoidea: Encyrtidae) was not reported earlier on M. desjardinsi. The Encyrtid, Copidosomyia ambiguous can be diagnosed based on the following characters: Body black except for the following parts: Antennae except for the clava brown, clava pale yellow; mid femora and tibiae, basal part of hind tibiae white; apices of mid tibiae, spurs, mid tarsi pale white to yellow, hind tarsi dark brown. Hind femur fully brown; hind tarsus completely dark brown (scape 9× as long as wide; pedicel less than 0.25× scape length); funicle segments 1-4 longer than broad, fifth almost quadrate, sixth broader than long, clava longer than the combined lengths of the three funicle segments. Postmarginal vein is very long shorter than the stigmal costal cell broad with two rows of fine setae; the marginal fringe is very short; the mid-tibial spur is very long, slightly shorter than basitarsus (29:34). The distribution of this pupal parasitoid was in Bangladesh, India (Bengaluru and Tamil Nadu). In the present study emergence potential of these pupal parasitoids was studied, and the emergence range of Copidosomyia ambiguous (Subba Rao) adults was observed from 29.17 to 62.50 percent against M desjardinsi in different months from July to December. The maximum emergence was maximum at the first fortnight of July (62.50 percent), followed by August's second fortnight (60.87 percent). A fluctuation in the emergence range of Copidosomyia ambiguous was observed in subsequent months. In the case of Ichnemonid, Dicrogaster sp. parasitoid population was minimum compared to Copidosomyia ambiguous. The emergence range of Dicrogaster sp. was from 4.35 to 18.18 percent against M. desjardinsi.
