Interactions in arthropod biological control communities

It is clear that the way we live in general, and agriculture in particular, needs to become more sustainable. Therefore, our research focuses increasingly on biological control of plant-inhabiting arthropod pests as an alternative to chemical pest control. This encompasses research on potential biological control agents (Nomikou et al., 2001, 2002; van Maanen et al., 2010; da Silva et al., 2016; Rodríguez-Cruz et al., 2017), but because increased applications of biological control leads to a multiplication of the interactions among pest and natural enemy species, we also investigate the effects of such interactions. In particular, we study how biological control is affected by interactions among plants, herbivores, omnivores and natural enemies of herbivores. Here is a list.

 

1. Apparent competition between plant pests

Populations of different pest species that are attacked by the same population of natural enemies are involved in apparent competition (Holt, 1977). The consequences of apparent competition for biological control can be either positive or negative at a short time scale, but are predominantly positive at a longer time scale. This means that natural enemies that attack more than one pest species can be carefully selected to improve pest control. The advantage is that natural enemies that attack several pest species are less dependent on the presence of either of the pests and can reach higher densities because there is more food available. An excellent example of this is based on the pioneering research from our group: the use of the predatory mite Amblyseius swirskii for the control of thrips plus whiteflies (Nomikou et al., 2001; Messelink et al., 2008). This species is now commonly used for biological control. Several predator species actually perform better on a diet of mixed prey species (Messelink et al., 2008; Muñoz-Cárdenas et al., 2014; Marques et al., 2015), which results in further increases of predator populations and better pest control.

 

2. Alternative food

A topic closely related to apparent competition is the supply of alternative food to boost populations of natural enemies. Although research on this goes back several decades (Ramakers, 1980), it has become practice in European greenhouses only recently. We are particularly interested in the short-term and long-term dynamics of pests and natural enemies in the presence of alternative food supplied on the crop plants (Nomikou et al., 2002; van Rijn et al., 2002; van Maanen et al., 2010; Duarte et al., 2015), or elsewhere in the cropping system (Muñoz-Cárdenas et al., 2017). Many plant species produce pollen and nectar, which are important food sources for natural enemies of herbivores (see Interactions through the host plant below). Such plants can be associated with crops to supply alternative food, thus increasing pest control (Rezende et al., 2014; Fonseca et al., 2017).

 

3. Intraguild predation among natural enemies

This is the killing and consuming of potential competitors (Polis & Holt, 1992), which occurs frequently among predators used for biological control (Cakmak et al., 2006). For example, two predatory bugs are used for biological control of aphids and thrips, both feed on nectar and pollen in the flowers of sweet pepper and one of the predators attacks and kills the other (Messelink & Janssen, 2014). Theory predicts that intraguild predation will often have negative effects on biological control, but experiments and observations suggest that this is often not the case (Janssen et al., 2006). Using biological control systems, we investigate causes for this discrepancy between theory and reality. Often, the stage structure or size structure of the populations of predators are important for intraguild predation, with older stages of one species feeding on younger, smaller stages of the other species (Montserrat et al., 2008), and it is common that adults of pairs of species attack each other's juveniles. This so-called reciprocal intraguild predation can easily result in exclusion of one of the predator species (Montserrat et al., 2012), and it is still very much an open question how and why populations of species interact in this way are still found to coexist.

 

4. Role reversals in predator-prey systems

Species are often ascribed one ecological role: they are predators or prey. Reality is more complex: for example, thrips larvae are considered a plant pest and prey, but they attack the eggs of their predators (Faraji et al., 2002; Janssen, Faraji, et al., 2002; Magalhães et al., 2005; de Almeida & Janssen, 2013). Predators involved in reciprocal intraguild predation start their lives as prey and develop into predators while maturing. We suspect that such ontogenetic role reversals are quite common, and are currently investigating this.

 

5. Behaviour and learning

Prey avoid predators and predators try to find prey. This dynamic game of hide and seek occurs both in natural ecosystems as in the ecosystems occurring in crops in which biological control is applied. We investigate these behaviours and their effects on predator-prey interactions (Pallini et al., 1998; Venzon et al., 2000; Magalhães et al., 2002; Meng et al., 2006; Lemos et al., 2015; Choh et al., 2017). We also investigate how experience with predation risk changes behaviour of prey (pests) (Nomikou et al., 2003), and how experience with prey-associated cues changes the searching behaviour of predators (Janssen et al., 2014). Ontogenetic role reversals (see Role reversals in predator-prey systems) has interesting behavioural consequences; whereas young individuals need to avoid the other species, they can attack them when adult. Experience of an individual with an adult predator early in life results in increased predation on the juveniles of this predator species later in life (Choh et al., 2012, 2014).

 

6. Plant-mediated interactions

Plants are not just the substrate on which all interactions occur, but they have an active role (Sabelis et al., 1999; Kant et al., 2015). They can defend themselves through the production of compounds that have negative effects on herbivore performance (direct plant defences). Often, these defences are only activated upon herbivore attack (induced defences). Plants can also involve the natural enemies of their herbivores in their defence (indirect plant defences). They can do this by supplying the natural enemies with alternative food such as pollen and nectar (see Alternative food above), or by offering protective structures to the predators (Matos et al., 2006; Ferreira et al., 2011). Plants attacked by herbivores also produce volatiles that attract natural enemies (so-called herbivore-induced plant volatiles). In response to these induced direct and indirect plant defences, several herbivore species are found not to induce such defences, or even suppress them (Sarmento et al., 2011; de Oliveira et al., 2016; Godinho et al., 2016). Furthermore, omnivores that are used as biological control agents also feed on plants and induce such plant defences (Zhang et al., 2018). We study the effects of these plant defences on the arthropod communities on plants, as well as their effects on biological control.

 

7. Further scientific “hobbies”…

Several topics on which I have worked in the past do not occur in this list because we temporarily do not work on them. This is not because of lack of interest, but because of shortage of projects and time. These topics include the interaction of organisms with pathogens (Elliot et al., 2000; Belliure et al., 2005; van Munster et al., 2005), behavioural manipulation of hosts by parasites (Grosman et al., 2008) and work on parasitoids in general (Janssen et al., 1995), adaptation in herbivores (Groot et al., 2005; Magalhães et al., 2007), metapopulation dynamics (Ellner et al., 2001) and the evolution of indirect plant defences (Janssen et al., 2002). Fortunately, the last two topics have been picked up again recently through a collaboration with Josinaldo Menezes and Kateřina Staňková. I hope the same will happen with the other topics.

 

Acknowledgements

Perhaps you think I exaggerated the number of citations of own work in the text above, for which I apologize. However, they show the people with which I have been fortunate enough to collaborate and I want to express my gratitude by citing our joint publications. This also saves me the effort of having to mention all of them here. I am sure that some are missing, for which I also apologize. Without exception, they all showed a truly inspirational passion for research, and I am happy that several of them have become close friends. I need to mention one person by name though, which is Maurice Sabelis, who sadly passed away much too early. Those who knew him need no explanation; for those who did not, words fail me.

A spider mite that manipulates plant defence

When herbivores such as spider mites attack a plant, complex plant defence mechanisms are activated.In collaboration with colleagues from the Federal Universities of Viçosa and Tocantins, Brazil, we discovered that certain spider mites are able to disrupt these mechanisms, effectively disarming the plant.

Phytopathogens and herbivores induce plant defences. There is evidence that some pathogens suppress these defences by interfering with signaling pathways involved in the defence, but such evidence is scarce for herbivores. We found that the invasive spider mite Tetranychus evansi suppresses the induction of signaling routes involved in induced plant defences in tomato. As a result, the mites performed much better on previously attacked plants than on non-attacked plants. These findings provide a new perspective on plant-herbivore interactions, plant protection and plant resistance to invasive species.
Another mite species, the closely related T. urticae can also profit from the suppression of induction of defence by T. evansi . However, the latter protects leaf area with down-regulated plant defence by covering it with a dense web that is difficult to penetrate by T. urticae .

Parasitoid turns its host into a bodyguard

Parasites can induce dramatic changes of behaviour in their host species. This behaviour is thought to be detrimental to the host, but beneficial to the parasite. In a joint publication, researchers from the University of Amsterdam and University of Viçosa ( Brazil ) show evidence of spectacular behavioural changes induced by a parasitic wasp in the caterpillar of a moth species.

After the wasp ( Glyptapanteles sp.) has oviposited eggs in the body of a caterpillar ( Thyrinteina leucocerae ), these develop into larvae that live on the body fluids of the caterpillar. After the wasp larvae crawl out of the caterpillar to pupate, the caterpillar acts as a bodyguard to defend them from predator attacks. This results in a twofold reduction of predation of the wasp pupae in the field.

After several days, the adult wasps emerge from their pupae and the caterpillar dies.
