Tachinidae, Tachinid Flies
Beneficial Insects Class Insecta, Insects Order Diptera, Flies, gnats, and midges Diptera means “two wings,” and true flies bear only one pair of functional wings. Flies are one of the largest insect groups, with approximately 35 families that contain predatory or parasitic species. All flies have piercing/sucking/sponging mouthparts. Tachinid flies Family Tachinidae Description and life history: This is a large and important family, with up to 1300 native parasitoid species in North America and additional introduced species to help control foreign pests. These flies vary in color, size, and shape but most resemble houseflies. Adults are usually gray, black, or striped, and hairy. Adults lay eggs on plants to be consumed by hosts, or they glue eggs to the outside of hosts, so the maggots can burrow into the host. Rarely will tachinids insert eggs into host bodies. Tachinid flies develop rapidly within their host and pupate in 4–14 days. By the time they emerge, they have killed their host. Many species have several generations a year, although some are limited by hosts with a single annual generation. Prey species: Most tachinid flies attack caterpillars and adult and larval beetles, although others specialize on Tachinid fly adult. (327) sawfly larvae, true bugs, grasshoppers, or other insects.

Japanese Beetles This Year Again Proposes for a Dramatic Increase in the Populations of Japanese Beetles
Japanese Beetles This year again proposes for a dramatic increase in the populations of Japanese beetles. These beetles can be very damaging in both their adult and larval stage. Beetles are approximately 3/4" long, and are easily distinguished by their blue/green//brown/silver color, which is shiny and makes them look like they are made out of metal. Typically they are unlike anything you are used to seeing. The most damaging and expensive injury caused by Japanese beetle is by its larval stage feeding on the roots of turf grass. Browning turf, in spotted areas, which can be pulled up in clumps is a sure sign. The less concerning, but most noticeable, damage occurs to the leaves of many different species of plants. Leaves will be eaten, with only the leaf veins remaining (looks similar to lace). Trees can be treated with a foliar application, which will only be effective for only a few days, an injected systemic insecticide, or by soil applied insecticide. The truly effective, and least costly, way to treat for beetles is not to treat the tree at all, but to eliminate them in the larval stage (in the soil). The beetles lay eggs in the soil, which over-winter and mature as grubs, which feed on grass and other roots. A turf grub control treatment in early to mid May will reduce and control the adult populations. It is very difficult to fully eliminate the beetles as they may reside in your neighbors turf as well. The solution is to take this information to your neighbors and institute a cooperative plan to treat the turf, and/or otherwise manage the pest in the spring. -

New Canadian and Ontario Orthopteroid Records, and an Updated Checklist of the Orthoptera of Ontario
Checklist of Ontario Orthoptera (cont.) JESO Volume 145, 2014 NEW CANADIAN AND ONTARIO ORTHOPTEROID RECORDS, AND AN UPDATED CHECKLIST OF THE ORTHOPTERA OF ONTARIO S. M. PAIERO1* AND S. A. MARSHALL1 1School of Environmental Sciences, University of Guelph, Guelph, Ontario, Canada N1G 2W1 email, [email protected] Abstract J. ent. Soc. Ont. 145: 61–76 The following seven orthopteroid taxa are recorded from Canada for the first time: Anaxipha species 1, Cyrtoxipha gundlachi Saussure, Chloroscirtus forcipatus (Brunner von Wattenwyl), Neoconocephalus exiliscanorus (Davis), Camptonotus carolinensis (Gerstaeker), Scapteriscus borellii Linnaeus, and Melanoplus punctulatus griseus (Thomas). One further species, Neoconocephalus retusus (Scudder) is recorded from Ontario for the first time. An updated checklist of the orthopteroids of Ontario is provided, along with notes on changes in nomenclature. Published December 2014 Introduction Vickery and Kevan (1985) and Vickery and Scudder (1987) reviewed and listed the orthopteroid species known from Canada and Alaska, including 141 species from Ontario. A further 15 species have been recorded from Ontario since then (Skevington et al. 2001, Marshall et al. 2004, Paiero et al. 2010) and we here add another eight species or subspecies, of which seven are also new Canadian records. Notes on several significant provincial range extensions also are given, including two species originally recorded from Ontario on bugguide.net. Voucher specimens examined here are deposited in the University of Guelph Insect Collection (DEBU), unless otherwise noted.

Steinernema Neocurtillis N. Sp
JOURNAL OF NEMATOLOGY VOLUME 24 DECEMBER 1992 NUMBER 4 Journal of Nematology 24(4):463--477. 1992. © The Society of Nematologists 1992. Steinernema neocurtillis n. sp. (Rhabditida: Steinernematidae) and a Key to Species of the Genus Steinernema 1 KHUONG B. NGUYEN AND GROVER C. SMART, JR. 2 Abstract: Steinernema neocurtillis n. sp. isolated from the mole cricketNeocurtilla hexadactyla Perty can be distinguished from other members of the genus by characteristics of the first-generation male and the third-stage infective juvenile (IJ). In the male, the distance from the anterior end to the excretory pore (DAE) is less than the body width at the excretory pore; D% (DAE divided by length of esophagus x 100) is low at 19. The gubernaculum l~figth is greater than three-fourths the spicule length. Range of the ratio gubernaculum length divided by spicule length is 0.82-0.93 in the first- generation male and 0.92-1.00 in the second-generation male. In the IJ, the distance fl-om the anterior end to the excretory pore is extremely short (18 p~m), causing the D% and E% (DAE divided by tail length x 100) to be low (D% = 23 and E% = 12). Average body length of the IJ is 885 ~m.
