Seasonal incidence of sugarcane planthopper Pyrilla perpusilla Walker (Hemiptera: Lophopidae) and its natural enemies was investigated at Cuddalore District, Tamil Nadu during 2018.  In this study, Fulgoraecia melanoleuca, a parasitoid of sugarcane planthopper Pyrilla perpusilla was observed in large numbers in the field.  Brief notes on its biology, life stages, and extent of parasitism on the host were studied.  Per cent parasitization in nymph and adult was 47.54 and 45.09, respectively, during the month of August.  High resolution images of all life stages are provided to help in identification.

Abstract Background Fulgoraecia melanoleuca (Fletcher) (Lepidoptera: Epipyropidae) (= Epipyrops or Epiricania melanoleuca) is an important koinobiont nymphal and adult ectoparasitoid of sugarcane leafhopper, Pyrilla perpusilla (Walker) (Hemiptera: Lophopidae). The study aimed to evaluate whether and to what extent this parasitoid effects the fitness of immature (five nymphal stages) and adult (♂ and ♀) stages of its host P. perpusilla. Results The nymphal mortality was significantly more in the younger nymphs, and it decreased as the host aged. The exposure of the first stage host nymphs to the parasitoid resulted in 100% mortality. However, the nymphal mortality rates in second, third, fourth and fifth nymphal stage were 94.0, 75.0, 38.0 and 41.0%, respectively. Furthermore, the longevity of surviving nymphs was prolonged significantly in the later stages. None of the parasitized first to fourth stage nymphs survived as normal adult. In case of the parasitized fifth nymphal stage, 18.0% adults were normal; however, their longevity was comparatively shorter than their un-parasitized counter parts. When male and female adults of leafhopper were offered to the parasitoid, significant differences were found in mortality of parasitized and un-parasitized adults for both sexes. Further, parasitoid-induced prolongation in the longevity of the surviving parasitized adults was also observed. Conclusions Overall, the parasitoid F. melanoleuca had detrimental effects on host fitness and thus played a significant role as a biological control agent in suppressing the sugarcane leafhopper population. This study will clarify host-parasitoid relationship, developing mass rearing protocol under laboratory conditions and implementing effective strategies for augmentative releases of parasitoids in biological control program against P. perpusilla in sugarcane ecosystem.

And Control

Pyrilla perpusilla, Wlk., is one of the most destructive sugar-cane pests in the Punjab. It is widely distributed and, in addition to sugar-cane, it also feeds on wheat, barley, oats, maize, “chari” and a number of grasses.Descriptions of the egg, nymphal and adult stages are given.A female can lay 773 eggs in its life-time. The eggs are laid in clusters on the food-plants and are covered with whitish fluffy material. The egg stage occupies 7–12 days during April–October and 20–41 days during November–March. There are five nymphal instars. The nymphal stage occupies 24–65 days during April–September and 78–208 days during October–March.Both adults and nymphs do damage. They prefer to feed on those varieties of sugar-cane which have broad, fleshy and succulent leaves and thick, soft stems. As a result of their feeding sucrose is reduced by as much as 34·2 per cent., while the glucose ratio may be trebled.The pest is parasitised by the following insects:—Ooencyrtus papilionis, Ashm., Tetrastichus pyrillae, Craw., and Lestrodryinus pyrillae, Kieff. (Hymenoptera); and Pyrilloxenos compactus, Pierce (Stylopidae). The following are predacious upon it: Brumus suturalis, F., Chilomenes sexmaculatus, F., Coccinella septempunctata, L., and C. undecimpunctata, L. (Col.), and Epipyrops sp. (Lep.). The incidence and duration of the life-cycles of these parasites and predators are given.To control the pest the following measures are suggested:—(1) Destruction of the adults by hand nets during April; (2) destruction of the eggs by crushing during April; (3) destruction of the nymphs by a new hopperdozer during November–March; (4) dusting with nicotine dust or spraying with nicotine sulphate-fish oil soap mixture.
