  • Cannibalism Among Same-Aged Nymphs of the Omnivorous Predator Dicyphus Errans (Hemiptera: Miridae) Is Affected by Food Availability and Nymphal Density
    EUROPEAN JOURNAL OF ENTOMOLOGYENTOMOLOGY ISSN (online): 1802-8829 Eur. J. Entomol. 116: 302–308, 2019 http://www.eje.cz doi: 10.14411/eje.2019.033 ORIGINAL ARTICLE Cannibalism among same-aged nymphs of the omnivorous predator Dicyphus errans (Hemiptera: Miridae) is affected by food availability and nymphal density KONSTANTINA ARVANITI 1, ARGYRO FANTINOU 2 and Dionyssios PERDIKIS 1 1 Laboratory of Agricultural Zoology & Entomology and 2 Laboratory of Ecology & Environmental Sciences, Agricultural University of Athens, Iera Odos 75, 118 55, Athens, Hellenic Republic; e-mails: [email protected], [email protected], [email protected] Key words. Hemiptera, Miridae, Dicyphus errans, adult weight, cannibalism, density, development, food availability, omnivorous predator Abstract. Cannibalism, the act of eating an individual of the same species has been little studied in omnivorous insect predators. Dicyphus errans (Wolff) (Hemiptera: Miridae) is a generalist omnivorous predator that commonly occurs in tomato greenhouses and fi eld crops in the Mediterranean basin. In this work cannibalism among same-aged neonate nymphs of D. errans was studied when 1, 2, 4, 8 or 16 individuals were placed in a Petri dish along with or without heterospecifi c prey. Although nymphs were un- able to complete their development in the absence of prey they survived longer when there were initially 2 individuals per dish than in any other treatment including a single individual. This may indicate that cannibalism in this predator has positive effect on nymphal survival, which however was not the case at higher densities. The presence of heterospecifi c prey increased nymphal survival and individuals were as equally successful in completing their development as when kept singly.

  • ARTHROPODA Subphylum Hexapoda Protura, Springtails, Diplura, and Insects

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

Simple Summary: Biological control (BC) is an effective way to regulate pest populations in hor- ticultural crops, allowing the decrease of pesticide usage. On tomato, predatory insects like plant bugs or mirids provide BC services against several insect pests. Native predators are adapted to local conditions of climate and ecology and therefore may be well suited to provide BC services. Dicyphus cerastii is a predatory mirid that is present in the Mediterranean region and occurs in tomato greenhouses in Portugal. However, little is known about its contribution to BC in this crop. In this study, we evaluated how prey consumption is affected by increasing prey abundance on four different prey, in laboratory conditions. We found that the predator can increase its predation rate until a maximum is reached and that prey characteristics like size and mobility can affect predation.

    16 Tea is a perennial monoculture crop, which provides suitable microclimate as well as continuous supply of food to number of arthropods. Each tea population within an agro-climatic area has its distinctive pest problem. The classical work of Watt and Mann (1903) offers the basic knowledge of tea pests occurring in Asia. Cranham ( 1966) and subsequently Muraleedharan (1983) reviewed the pest problems of this crop, on a global basis. Our knowledge of tea pests in North-East India is mainly based on the contribution of Cotes (1895), Watt and Mann (1903), Hainsworth (1992), Das (1965), Banerjee (1964, 1966a, 1966b, 1967, 1969, 1970, 1971 , 1976 and 1977) Gurusubramanian et al., (2005). Origin, taxonomic character and distribution of He/ope/tis spp Plant bugs of Genus Helopeltis are serious pest of various cultivated plants in the old world tropics. The damaging effect of these insects on tea plants in India was documented over a century ago in reports by Peal (1973) and Wood-mason (1884). It was in these early accounts that the common name "tea-bug" and "tea-mosquito" were established, along with various names referring to feeding injury such as "tea­ blight", " mosquito-blight" and "spot-blight" etc. Since the late 1800s over 100 species of plants have been reported as host for He lope/tis spp. including a number of major cash crops such as black pepper (Piper nigrum), cashew (A nacadium occidentale), cinchona (Cinchona spp.), cocoa (Theobroma cocoa) and Tea (Camellia sinensis). In tea it was first recorded in Java in the year 1847 (Rao, 1970). In Ind ia the pest was noticed in the year 1968 in Cachar (Watt and Mann, 1903) Helopeltis belongs to the subfamily Bryocorinae, tribe Dicyhini and subtribe Monaloniina, which is distinguished from other tribes of Bryocorinae by the elongate, 17 Oz [}'·C lCOJ cylindrical body form, the structure of the pretarsus, the reduced numbers of meso and metafemoral trichomae, the metathoracic sent efferent system lacking developed ostiole and evaporative area on metaepisternum and eggs with respiratory horns (Schuh, 1995).

Abstract: Zoophytophagous dicyphine mirids can produce economically important damage on tomato. We evaluated the influence of fruit ripeness and presence of prey and water, on fruit damage caused by nymphs and adults of two species (Dicyphus cerastii and Nesidiocoris tenuis) in 24h. For both species combined, fruit ripeness was the most important factor and unripe fruit suf- fered more damage. The presence of prey only reduced damage on unripe fruits. Factor importance on fruit damage varied between species. For D. cerastii fruit ripeness was the most important factor whereas for N. tenuis it was mirid age. Overall, N. tenuis females produced more damage than D. cerastii. Keywords: fruit injury; biological control; mirid; dicyphini; protected crops 1.

In multi-choice trials all developmental stages of the predator tested, namely N3, N5, and adult female, showed a clear preference for Aphis gossypii Glover over other prey species offered. Nonetheless, a considerable number of Tetranychus urticae Koch, Frankliniella occidentalis (Pergande), and Trialeurodes vaporariorum (Westwood) were also consumed. Myzus persicae (Sulzer) was the least preferred by all the predatory stages tested. In a separate experiment, D. tamaninii was able to complete its development from N1 to adult stage in an average of 21 days, with 20% mortality, when offered only T. urticae as prey.As testing all of the potential interactions with other beneficial arthropods is not practical, the present study focused on 3 natural enemies most likely to be disrupted by a possible release of D.

  • Investigating Thermal Physiology As a Tool to Improve the Release Efficacy of Insect Biological
    Investigating thermal physiology as a tool to improve the release efficacy of insect biological control agents. THESIS Submitted in fulfilment of the requirements for the degree MASTER OF SCIENCE at Rhodes University By Tamzin Camilla Griffith January 2018 i Abstract Biological control is commonly used for the control of invasive aquatic weeds, which often involves the release of multiple host-specific agents. Releasing multiple agents has inherent safety concerns as the introduction of each new agent is associated with risks, but is often required to improve control where establishment is limited. Climatic incompatibility between the agent’s thermal physiology and its introduced range often causes agents to fail to establish. However, it has been suggested that the thermal physiology of insects is plastic. Therefore, the potential to manipulate their thermal physiologies before releasing them into the field needs to be explored; reducing the need to release additional agents, thereby ensuring the safety of biological control. This thesis therefore aimed to firstly, determine whether season and locality influenced the thermal physiology of two field populations of a water hyacinth (Eichhornia crassipes) control agent, the mirid Eccritotarsus catarinensis; one collected from the hottest establishment site, and one collected from the coldest establishment site in South Africa. Their thermal physiology was significantly influenced by season and not by the sites’ climate, suggesting their thermal physiology is plastic under field conditions. Secondly, the classical method of determining the lower critical thermal limit (CTmin), and a new respirometry method of determining this limit, compared the thermal physiology of two Eccritotarsus species reared in quarantine. Eccritotarsus catarinensis was significantly more cold tolerant than the more recently released Eccritotarsus eichhorniae, despite similar maintenance conditions, and as such, was used to establish whether cold hardening under laboratory conditions was possible.
