Conclusions Glossary UNESCO – EOLSS Bibliography Biographical Sketches Summary SAMPLE CHAPTERS Biological control is a pest control method with low environmental impact and small contamination risk for humans, domestic animals and the environment. Several success cases of biological control can be found in the tropics around the world. The classical biological control has been applied with greater emphasis in Australia and Latin America, with many success cases of exotic natural enemies’ introduction for the control of exotic pests. Augmentative biocontrol is used in extensive areas in Latin America, especially in the cultures of sugar cane, coffee, and soybeans.

    WEB-INTEGRATED TAXONOMY AND SYSTEMATICS OF THE PARASITIC WASP FAMILY SIGNIPHORIDAE (HYMENOPTERA, CHALCIDOIDEA) A Dissertation by ANAMARIA DAL MOLIN Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, James B. Woolley Committee Members, Mariana Mateos Raul F. Medina Robert A. Wharton John M. Heraty Head of Department, David Ragsdale December 2014 Major Subject: Entomology Copyright 2014 Anamaria Dal Molin ABSTRACT This work focuses on the taxonomy and systematics of parasitic wasps of the family Signiphoridae (Hymenoptera: Chalcidoidea), a relatively small family of chalcidoid wasps, with 79 described valid species in 4 genera: Signiphora Ashmead, Clytina Erdös, Chartocerus Motschulsky and Thysanus Walker. A phylogenetic analysis of the internal relationships in Signiphoridae, a discussion of its supra-specific classification based on DNA sequences of the 18S rDNA, 28S rDNA and COI genes, and taxonomic studies on the genera Clytina, Thysanus and Chartocerus are presented. In the phylogenetic analyses, all genera except Clytina were recovered as monophyletic. The classification into subfamilies was not supported. Out of the four currently recognized species groups in Signiphora, only the Signiphora flavopalliata species group was supported. The taxonomic work was conducted using advanced digital imaging, content management systems, having in sight the online delivery of taxonomic information. The evolution of changes in the taxonomic workflow and dissemination of results are reviewed and discussed in light of current bioinformatics. The species of Thysanus and Clytina are revised and redescribed, including documentation of type material. Four new species of Thysanus and one of Clytina are described.

  • Sublethal Effects of Pesticides on the Parasitoid Aphytis Melinus (Hymenoptera: Aphelinidae)
    Sublethal Effects of Pesticides on the Parasitoid Aphytis melinus (Hymenoptera: Aphelinidae) JAY A. ROSENHEIM ANDMARJORIE A. HOY Department of Entomological Sciences, University of California, Berkeley, California 94720 J. Econ.Entomo!.81(2): 476-483 (1988) ABSTRACT Sublethal effects of insecticides on the parasitoid Aphytis melinus DeBach were investigated. Longevity, daily rate of progeny production per female, and size and sex ratio of offspring were measured for parasitoids exposed to rates near the LC,;s of carbaryl, chlorpyrifos, dimethoate, malathion, and methidathion. Survivorsof the exposure to carbaryl exhibited no significantsublethal effects.Exposure to each of the organophosphorous materials reduced longevity by 73-85% and temporarily depressed progeny production. Chlorpyrifos also shifted the sex ratio of offspring toward more males. The strength and variability of sublethal effects found in this and other studies indicate that sublethal effects must be considered to evaluate accurately the selectivity of pesticides in favor of parasitoids.

  • Adult Feeding and Lifetime Reproductive Success in the Parasitoid Aphytis Melinus
    Entomologia Experimentalis et Applicata 83: 305±315, 1997. 305 c 1997 Kluwer Academic Publishers. Printed in Belgium. Adult feeding and lifetime reproductive success in the parasitoid Aphytis melinus George E. Heimpel1;2, Jay A. Rosenheim1 & David Kattari1 1Department of Entomology, University of California, Davis, CA 95616, USA; 2 Current address: Department of Entomology, University of Wisconsin, Madison WI, 53706, USA Accepted: March 4, 1997 Key words: Aphytis melinus, biological control, host feeding, parasitoids Abstract The diet of adult females of the parasitoid Aphytis melinus DeBach (Hymenoptera: Aphelinidae) includes host insects and sugar-rich foods such as nectar and honeydew. We compared the contributions of host feeding to longevity and fecundity in A. melinus females in the presence and in the absence of honey meals. First, we assessed the longevity of females that were not allowed to oviposit. While the longevity of females fed honey was signi®cantly increased by host feeding (median ages were 30.5 days for host-fed females and 17 days for females not allowed to host feed), the lifespan of parasitoids not fed honey did not exceed 3 days for any individual and there was no effect of host feeding on longevity in this group. In the second set of experiments, we assessed the fecundity and longevity of females allowed to oviposit. We conducted two experiments, one in which honey was continuously available, and one in which honey was not available. In both experiments, daily observations were made of females that were either allowed to host feed or manually prevented from host feeding. In the presence of honey, host feeding signi®cantly increased both fecundity and longevity, and in the absence of honey, parasitoids died within 2 days and host feeding had no signi®cant effect on either fecundity or longevity.

    Journal of Entomology and Zoology Studies 2016; 5(1): 692-696 E-ISSN: 2320-7078 P-ISSN: 2349-6800 Aphelinid wasps (Hymenoptera, Aphelinidae) – JEZS 2017; 5(1): 692-696 © 2017 JEZS parasitoids of scale insects (Hemiptera, Received: 03-11-2016 Accepted: 04-12-2016 Diaspididae) in Azerbaijan Mustafayeva Gulzar Aligeydar PhD, Institute of Zoology, Azerbaijan National Academy of Mustafayeva Gulzar Aligeydar Sciences, Baku c, Azerbaijan AZE -1073, pr.1128, bl.504 Abstract A review of aphelinid parasitic wasps (Hymenoptera, Aphelinidae) obtained from their scale hosts in Azerbaijan is provided for the first time. As a result of long-term investigation, 30 species of aphelinids were revealed in the fauna of Azerbaijan. Of these, one species was described as a new for science and six species were reported for the first time for the fauna of Azerbaijan. Keywords: Pests, scale insects, parasitoids, aphelinids, fauna, trophic relationships Introduction In the integrated system of protection of plants against sucking pest insects and diseases distributed by them an important role plays biological control, including use of natural enemies, such as entomophages and parasitoids. Aphelinids as effective enemies of many harmful sucking insects, such as coccids, aphids, aylerodids are successfully used in biological control. However, despite their high effectiveness, this group of parasitoids is still insufficiently used in the integrated system of protection of plants against pests in Azerbaijan. Therefore, the studying aphelinid fauna of Azerbaijan is actual and important as bases for development of ways of their practical application in plant protection in Republic. The first report on Aphelinidae of Azerbaijan includes 29 species [4].

In this research, we investigated the VOC chemical signals for the parasitoid Aphytis melinus to discriminate between Aonidiella aurantii (California red scale)-infested fruit and non-infested fruit on three different citrus species. First, we identified the chemical stimuli emanating from non-infested and A. aurantii-infested citrus fruits via solid phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS) analyses and identified 34 volatile organic compounds (VOCs). The GC-MS analysis showed qualitative and quantitative differences between VOCs emitted from non-infested and infested citrus fruit.

The efficacy of natural enemies in controlling pests under field conditions is largely correlated with their capacity to spread within infested crops. In this study the spatial dispersal of the California red scale parasitoid Aphytis melinus DeBach (Hymenoptera: Aphelinidae) was evaluated in the field after augmentative releases. The experiment was conducted in 2007 in six 1-ha plots in a Sicilian citrus orchard under integrated pest management. A total of 180,000 A. melinus adults was released in each of three plots and the other plots were left as untreated control. The flight range of the parasitoid was evaluated, for 35 days after the release, on 16 trees per each plot, located at 20 and 40 m from the central release point using yellow sticky traps activated with Aonidiella aurantii (Maskell) (Hemiptera: Diaspididae) sexual pheromone and by monitoring the percentage parasitism of the scale on fruits and twigs.
