Brailovsky: A Revision of the Genus Amblyomia 475 A REVISION OF THE GENUS AMBLYOMIA STÅL (HETEROPTERA: COREIDAE: COREINAE: LEPTOSCELINI) HARRY BRAILOVSKY Instituto de Biología, UNAM, Departamento de Zoología, Apdo Postal 70153 México 04510 D.F. México ABSTRACT The genus Amblyomia Stål is revised and two new species, A. foreroi and A. prome- ceops from Colombia, are described. New host plant and distributional records of A. bifasciata Stål are given; habitus illustrations and drawings of male and female gen- italia are included as well as a key to the known species. The group feeds on bromeli- ads. Key Words: Insecta, Heteroptera, Coreidae, Leptoscelini, Amblyomia, Bromeliaceae RESUMEN El género Amblyomia Stål es revisado y dos nuevas especies, A. foreroi y A. prome- ceops, recolectadas en Colombia, son descritas. Plantas hospederas y nuevas local- idades para A. bifasciata Stål son incluidas; se ofrece una clave para la separación de las especies conocidas, las cuales son ilustradas incluyendo los genitales de ambos sexos. Las preferencias tróficas del grupo están orientadas hacia bromelias. Palabras clave: Insecta, Heteroptera, Coreidae, Leptoscelini, Amblyomia, Bromeli- aceae The neotropical genus Amblyomia Stål was previously known from a single Mexi- can species, A. bifasciata Stål 1870. In the present paper the genus is redefined to in- clude two new species collected in Colombia. This genus apparently is restricted to feeding on members of the Bromeliaceae, and specimens were collected on the heart of Ananas comosus and Aechmea bracteata. -

An attempt was made to find out the BAU, Sabour, Bhagalpur, Bihar, effective management practice through application of agrochemicals to minimize vector activites &the India crop loss. Three bio rational molecules viz., Imidacloprid 17.8 SL @ 1.0 ml/3liter water, Acetamiprid 20% SP @1.0 gm/ liter water and KEM (Immunity Builder) @2.0 ml/ liter were sprayed at 15 day R. K. Verma interval and were evaluated against vector activity to reduce the leaf curl disease incidence. The Subject Matter Specialist, Krishi minimum disease incidence was recorded to the extent of (27.25%) coupled with highest fruit yield of Vigyan Kendra, Madhepura, 63.13 q/ha in the treatment T2 having two spraying of Acetamiprid 20% SP @1.0 gm/ liter water at an BAU, Sabour, Bhagalpur, Bihar, interval of fifteen days during Kharif 2019 cropping season. Maximum disease incidence (32.25%) in India control with lowest yield (54.23/ha). Infection by chili leaf curl disease complex adversely affected yield attributing characters during Kharif season. Highest cost-benefit ratio of 1:11.49 was obtained by two Dr. Bipul Mandal spraying of Acetamiprid 20% SP @1.0 gm/ liter water during Kharif crop season. -

Frankliniella insularis Distinguishing features Both sexes fully winged. Body and legs dark brown, fore tibiae and all tarsi largely yellow; antennal segment III and basal half of IV–V yellow; fore wing brown with base sharply paler. Head wider than long, anterior margin often slightly concave; three pairs of ocellar setae present, pair III slightly longer than and situated just lateral to margin of ocellar triangle; postocular setae pair I present, pair IV longer than diameter of hind ocellus. Antennae 8- segmented; apex of segments III–IV constricted and neck-like, each with sense cone forked; segment VI with base of sense cone elongate; VIII scarcely longer than VII. Pronotum with little sculpture medially; 5 pairs of major setae present; anteromarginal setae shorter than anteroangulars, one pair of minor setae present medially between posteromarginal Antenna submedian setae. Metanotum with 2 pairs of setae at anterior margin, campaniform sensilla present. Hind coxae with group of microtrichia on dorsal surface. Fore wing with 2 complete rows of veinal setae. Abdominal tergites V–VIII with paired ctenidia, on VIII anterolateral to spiracle; tergite VIII posteromarginal comb with moderately long teeth arising from triangular bases, but medially with 2 or 3 teeth missing. Sternites III–VII without discal setae. Male smaller than female, sometimes paler; tergite VIII with no posteromarginal comb; sternites III–VII with transverse pore plate. Related species Currently 230 species are listed in the genus Frankliniella, with up to 130 Antennal segment VI further names placed into synonymy (Nakahara, 1997). This high rate of synonymy has been due to unrecognized variability in size and color of so many species. -

Pramod Katti, Arunkumar, H. Sushila, N.B.K. Desai and Pampanna,Y. i Department of Agricultural Entomology, Main Agricultural Research Station, University of Agricultural Sciences, Raichur-584104, Karnataka, India Abstract The study was carried out at Main Agriculture Research Station, Raichur, during Rabi 2018. The precount population were recorded at one day before spraying, while the post treatment observations were recorded at 3, 5 and 7 days after each spraying. There are three sprays of different doses of Beauveria bassiana @ 400 g/acre, Lecanicillium lecanii @ 400 g/acre, Metarhizium anisopliae @ 400 g/acre, commercial neem based formulation 1500ppm @ 600 ml/acre, Beeauveria. bassiana @ 800 g/acre, Lecanicillium lecanii @ 800 g/acre and Metarhizium anisopliae @ 800 g/acre in capsicum at 20 days interval. The results revealed that the overall mean per cent reduction after the application of first, second and third spray was highest in commercial neem based formulation 1500 ppm @ 600 ml/acre (78.51 %) were found significantly superior than rest of the treatments. This was followed by B. bassiana @ 800 g/acre (68.68 %), M. anisopliae @ 800 g/acre (66.58 %), L. lecanii @ 800 g/acre (66.02 %), M. anisopliae @ 400 g/acre (61.10 %), L. lecanii @ 400 g/acre (59.12 %) and B. bassiana @ 400 g/acre (58.80 %) and these treatments were found significantly superior than control. The biorationals in the decreasing order of their efficacy were commercial neem based formulation 1500ppm @ 600 ml/acre > B. -
