“…IPM measures included the release of the predator Nesidiocoris tenuis (Reuter) in nurseries where it established and successfully controlled the S. American tomato pinworm (Calvo, Lorente, Stansly, & Belda, 2012). N. tenuis could also be used in combination with the predator Macrolophus pygmaeus (Rambur) in biological control programmes of the tomato pinworm (Michaelides et al, 2018).…”

“…Even though the control of pests principally depends on insecticides (Roditakis et al, ; Wang & Wu, ), the management of pests’ populations should also include preventive and other corrective measures (Naranjo & Ellsworth, ). Such measures should combine pheromone traps, predators, parasitoids, insect pathogens and plant extracts (Abd El‐Ghany, Abdel‐Razek, Ebadah, & Mahmoud, ; Alili, Doumandji, Benrima, Doumandji, & Doumandji, ; Biondi, Desneux, Amiens‐Desneux, Siscaro, & Zappalà, ; Messelink & Janssen, ; Michaelides, Sfenthourakis, Pitsillou, & Seraphides, ; Mollá, González‐Cabrera, & Urbaneja, ; Urbaneja, Montón, & Mollá, ). In addition, an excessive use of insecticides often leads to a reduction of their effectiveness due to survival of resistant genotypes (Perry, Yamamoto, Ishaaya, & Perry, ).…”

Tuta absoluta, known as the South American tomato pinworm, is one of the most disastrous pests of tomato cultivations, presently menacing tomato cultivations worldwide. In 2006, T. absoluta invaded Spain from South America. Since then, it was rapidly spread to most European, African and Asian countries. Such alien invasive species can minimize crop production, whereas the increasing use of insecticides raises various environmental concerns as well as on control costs, control failure and the toxicity to non‐target organisms. The S. American tomato pinworm is mostly controlled by chemical insecticides, and failure to control it is not a rare phenomenon. Resistance to numerous insecticides has been reported and is mainly due to the fact that farmers do not follow a sustainable resistance management scheme. Several examples have been reported from several countries where the tomato pinworm is present. In order to develop a successful insecticide resistance management (IRM) strategy for any major pest, one needs to identify the baseline toxicity to insecticides and then monitor susceptibility levels. In Cyprus, the current status of susceptibility levels to the main insecticides that are used to control T. absoluta has never been studied before. Herein, nine Cypriot populations of the pest were subjected to laboratory bioassays between 2016 and 2018 using the main insecticides applied against it. We found that the insecticides chlorantraniliprole and indoxacarb could not control the Cypriot T. absoluta populations anymore, with a resistance ratio (RR) >28 and 3–23, respectively. Furthermore, mortality achieved by those two insecticides was 20.6%–72% for chlorantraniliprole and 27.5%–78% for indoxacarb. However, the insecticides emamectin benzoate and spinosad are very effective, since mortality to both of them ranged between 99.5% and 100%.

“…The functional response of predators may vary depending on prey size (Aljetlawi et al, 2004), prey evasive behavior (such as movement), or due to the predator's attack stimuli and food satisfaction (Botteon et al, 2016). Our laboratory trials did not provide the same situations that the predator would be exposed to in the field, where many factors may contribute to changes in functional response, such as the generalist predation habit (Schenk & Bacher, 2002), the complexity of the natural environment, intraguild predation and prey limitation (Michaelides et al, 2017), the time to learn the environment and to search for prey (Holling, 1959), temperature conditions (Englund et al, 2011), and structure or chemical compounds of host plants (Malaquias et al, 2014(Malaquias et al, , 2015Jalali & Ziaaddini, 2016). The size of the predator-prey contact arena under laboratory conditions may force the predator to maintain greater or lesser contact with the prey densities provided and increase the probability of obtaining type II responses (Hassanpour et al, 2010;Papanikolaou et al, 2014;van Lenteren et al, 2016).…”

The diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae), is the main pest of brassica crops worldwide. The ringlegged earwig, Euborellia annulipes (Lucas) (Dermaptera: Anisolabididae), has been reported as a potential predator of lepidopteran larvae, including this pest, and may therefore be used for biological control. Knowledge about predator-prey interactions is important to establish pest management strategies. Therefore, the objective of this work was to evaluate the influence of the developmental stage (larva and pupa) and density of P. xylostella on the preference and functional response of E. annulipes adult females. We used choice and no-choice tests to evaluate the foraging behavior and preference of E. annulipes on DBM life stages and varied prey density to assess the type of functional response of the ringlegged earwig. Larvae were preferred over pupae, and the predator's functional response was type II for both prey stages. Our results report the potential of E. annulipes as a biocontrol agent of P. xylostella. Understanding their interactions may help in decision-making and optimization of integrated management strategies.

“…(Ingegno et al 2017). Eerdere studies met M. pygmaeus en N. tenuis melden een predatiecapaciteit van respectievelijk 50 en 70 eieren per dag (Michaelides et al 2018). Opvallend was dat het aantal larven dat per dag gegeten wordt een stuk lager ligt, waarschijnlijk omdat het de wantsen meer moeite kosten de prooi te vinden en door het blad heen aan te prikken.…”

Effecten van omnivore roofwantsen op plagen in gerbera, tomaat en roos en de risico's op bloem-en vruchtschade Omnivorous predators of the Miridae family feed both on plant and prey. This ability is a huge advantage for establishment into crops when pests are absent or scarce, but at the same time a risk when through plant feeding fruit and flowers get damaged. In this project we evaluated the potential for pest control with mirid predators in gerbera, rose and tomato crops. Pest control was assessed for whiteflies (gerbera and tomato), Echinothrips (gerbera and rose), Tuta absoluta (tomato), The Tomato Looper (gerbera and tomato) andNesidiocoris tenuis (tomato). In gerbera and tomato, not only pest control, but also the level of crop damage these mirids can cause was assessed. Finally, methods to enhance establishment were evaluated. AbstractOmnivore roofwantsen van de familie Miridae hebben de bijzondere eigenschap dat ze zowel van plantmateriaal als van prooien kunnen leven. Dit brede voedselmenu heeft enorme voordelen voor de biologische bestrijding, omdat ze daardoor verschillende plaagsoorten kunnen bestrijden en tegelijkertijd preventief ingezet kunnen worden doordat ze zich voeden met plantsappen en/of alternatief voedsel. Dit voordeel van plantenvoeding is tegelijkertijd een nadeel, omdat de wantsen ook schade kunnen geven aan bloemen en vruchten. In dit project is de potentie voor plaagbestrijding met een aantal soorten omnivore roofwantsen onderzocht in gerbera, roos en tomaat. De plaagbestrijding was gericht op wittevlieg (gerbera en tomaat), Echinothrips (roos en gerbera), Tuta absoluta (tomaat), Turkse mot (gerbera en tomaat) en Nesidiocoris tenuis (tomaat). Daarnaast hebben we gekeken naar de schade die ze kunnen veroorzaken in gerbera en tomaat en is gekeken naar methoden om vestiging te verbeteren.Stichting Wageningen Research.
