Dasineura Mali

The apple leaf midge, Dasineura mali (Kieffer), is an apple pest in Nova Scotia's Annapolis Valley (Rogers 1991). Larval D. mali are specialist, leaf-feeding pests that attack primarily young pubescent apple shoots. Larval feeding induces the leaves to curl tightly toward the midrib and form distinctive reddish galls that desiccate following larval exit. Economic damage to orchards in Annapolis Valley has not been estimated, but immature trees and nursery stock are vulnerable because new growth is essential for proper tree formation (Rogers 1991).

Damage Symptoms

In June 2015, infestations of sunflower crops by the bordered straw Heliothis peltigera (Lepidoptera: Noctuidae) were recorded in rural areas of the Regional Unit of Drama, N. Greece. Larval feeding-damage symptoms were observed on leaves and buds of sunflower plants, mostly at pre-flowering growth stages. Infestations were recorded in approximately 80% of the inspected sunflower fields, the infestation levels, however, were low (<5%) apparently resulting in no economic damage. The presence of H. peltigera has been reported in Southern and Central Europe, Canada, the Middle East and Africa, infesting several hosts. Infestations of sunflower crops have been reported in India, Pakistan and Sudan. To our knowledge, this is the first report of H. peltigera infestations on sunflower crops in Greece and possibly in Europe.

Dasineura Mali

Apple leafcurling midge (ALCM) is an important quarantine pest of New Zealand apples. Current methods for ALCM control have difficulty meeting the strict phytosanitary standards of some export markets. ‘Lure and kill’ is a new strategy against this pest, in which males are attracted to an insecticide-treated substrate where they collect a lethal dose. Trials were conducted using a gel matrix “Specialized Pheromone & Lure Application Technology” (SPLATâ„¢) to dispense and release the ALCM sex pheromone and the insecticide permethrin. Lures using SPLATâ„¢ were placed within plastic cylinder traps that collected the dead midges so they could be counted to determine treatment efficacy. The size, shape and age of SPLATâ„¢ spots influenced midge catches. Higher catches occurred with spots having a larger quantity of pheromone, greater surface area of SPLATâ„¢, or with fresh material. The implications for the development of a lure and kill strategy for ALCM are discussed.

Economic Pest

The apple brown bug, Atractotomus mali (Meyer), is an economic pest of apple in the Annapolis Valley of Nova Scotia (Rogers 1990). Feeding on developing fruit of sensitive apple varieties induces persistent corky scar tissue that reduces the quality of affected fruit. Forty-five percent of Annapolis Valley apple orchards monitored in 1992 required chemical insecticide applications to control the pest complex of A. mali and the mullein bug, Campylomma verbasci (Meyer) (Craig 1992).Female-produced sex pheromones occur in several mirid species, including the mullein bug (Smith et al. 1991) and Lygocoris communis (Knight) (Boivin and Stewart 1982). The sex pheromone of C. verbasci has been identified as a 16: 1 blend of butyl butyrate and crotyl butyrate (Smith et al. 1991). Our objective was to determine if a sex pheromone occurs in A. mali.

Invasive species, those that are nonnative and cause economic damage, are one of the main threats to ecosystems around the world. Ambrosia beetles are some of the most common invasive insects. Currently, severe economic impacts have been increasingly reported for all the invasive shot hole borers in South Africa, California, Israel, and throughout Asia. This 7-page fact sheet written by Demian F. Gomez, Jiri Hulcr, and Daniel Carrillo and published by the School of Forest Resources and Conservation describes shot hole borers and their biology and hosts and lists some strategies for prevention and control of these pests. http://edis.ifas.ufl.edu/fr422

Histomorphological Changes

Summary. Data on distribution of hypodermatosis among large horned cattle in Stavropol region are presented in the article. It was proved that this pathology is widespread in this region. From 12% to 38% of animals from the total number of examined livestock are affected. Ordinary subcutaneous botfly (stroma) Hypoderma bovis de Geer and south subcutaneous botfly (pischevodnik) Hypoderma lineatum de Villers parasites on large horned cattle. The species ratio of gadflies is: Hypoderma bovis (de Gee - 61.1%, Hypoderma lineatum de Villers - 38.9%). The disease is widespread in all climatic zones of Stavropol region. Animals of all age and sex groups are infected, but young animals are more often affected. Linear relationship between the indicators of the transformation of climatic conditions in Stavropol region, the spread of hypodermatosis and the timing of treatment and preventive measures were determined. Authors proved that the complete death of H. bovis and H. lineatum imago (regardless of the time of their hatching) was noted when the temperature drops to -3°C for two days. Thus, this temperature determines the start of treatment and preventive measures against hypodermatosis in the area of animal welfare. When analyzing the histomorphological changes caused by H. bovis and H. lineatum in the body of large horned cattle, perforation of the skin, swelling of adjacent tissues, disorganization of the stroma and structural elements, erythrocyte aggregation, hemorrhages, hydropic degeneration of cellular elements, tissue necrosis, polymorphonuclear leukocyte infiltration of affected organs and tissues were observed. The data on pathogenesis were presented, the analysis of economic damage and the veterinary and sanitary assessment of the products of slaughter of cattle with hypodermatosis were carried out.
