    Effect of microplastics and watering regimes on a plant-soil system: Data on behavioural responses of an insect herbivore

    No full text
    The data presented here are related to the article titled “Microplastics alter behavioural responses of an insect herbivore to a plant-soil system” by Rondoni, G., Chierici, E., Agnelli, A., Conti, E. (2021). The data describe the changes in the attractiveness of a plant-soil system towards females of a herbivorous fungus gnat (Diptera: Sciaridae) when exposed to different combinations of the following treatments: (1) low or high plant (lentil)-soil watering regime; (2) absence (0%) or presence (5%) of HDPE microplastics in soil; (3) 1-day or 7-day duration of HDPE presence; (4) addition of fungus mycelium to the plant-soil system. We report data of female behaviour, i.e. the residence time in choice vs. no-choice sector of one-way olfactometers using a multiple olfactometer device

    Egg parasitoids of stink bugs: Research status and potential for biological control

    No full text
    Egg parasitoids are among the most important natural enemies associated with herbivorous stink bugs, and they show remarkable potential as biological control agents. On the other side, some egg parasitoid species also attack predaceous bugs, thus affecting the efficacy of these important entomophagous insects. Most studied stink bug egg parasitoids belong to Platygastridae (=Scelionidae) and Encyrtidae, the main research topics concerning behavior, chemical ecology, behavioural ecology and field efficacy. Some species have been used for biological control programs. However, some constraints may prevent egg parasitoids from becoming effective agents in inundative biocontrol projects, the most important being incomplete behavioral and ecological knowledge for most species and inefficient mass production. Thus, understanding the host selection strategies of egg parasitoids and the chemical stimuli involved would lead to enhanced biological control through behavioral manipulation of egg parasitoids in the field, and to the development of better rearing methods. Egg parasitoids of herbivorous stink bugs may adopt differing host selection strategies, the most important being the exploitation of kairomones from non-target instars in combination with host-induced plant synomones (indirect resistance), and associative learning. The chemically mediated behavior of these wasps may be exploited, e.g., through the development of plants with elevated expression of indirect induced resistance, or spraying fields with resistance elicitors. Important elements toward implementation include procedures for selection of egg parasitoids, evaluation of their specificity, risk assessment of new introductions, release methods, and quality control. Implementation of knowledge acquired from laboratory studies must finally be scaled up and transferred to growers

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
