Insect Biology

Bacterial endosymbionts are common among arthropods including many important pest and beneficial insect species These symbionts provide either an obligate function performing essential reproductive or nutritive roles or are facultative influencing the ecology and evolution of their hosts in ways that are likely to impact biological control This includes resistance against parasitoids and modification to parasitoid fecundity Recent research has shown that endosymbionts are associated with exotic weevil pests found in New Zealand pasture including the clover root weevil Sitona obsoletus (S lepidus) The role of endosymbionts in insect biology and impacts on biological control is reviewed For New Zealand plant protection scientists endosymbiont research capability will provide important insights into interactions among insect pests plant hosts and biological control agents which may provide management opportunities for existing and future pest incursions in New Zealand

Chemical Stimuli

Plants under herbivore attack emit mixtures of volatiles that can attract the natural enemies of the herbivores. Entomopathogenic nematodes (EPNs) are organisms that can be used in the biological control of insect pests. Recent studies have shown that the movement of EPNs is associated with the detection of chemical stimuli from the environment. To date, several compounds that are responsible for the mediation in below ground multitrophic interactions have been identified. In the review, we discuss the use of EPNs in agriculture, the role of belowground volatiles and their use in plant protection programmes.

Microctonus Aethiopoides

Several candidate biological control agents of Sitona lepidus have been identified since a search commenced in 1997 Interestingly Microctonus aethiopoides from Europe is a much more effective parasitoid of S lepidus than the M aethiopoides ecotype already established in New Zealand To assess further the suitability of the European M aethiopoides for biological control of S lepidus 1599 infected S lepidus were shipped to New Zealand quarantine during late 2000 These yielded 267 parasitoid pupae from which 204 adult parasitoids were reared This material was obtained from a wide geographical range in Europe and has been used to establish cultures in New Zealand quarantine based on genetic material from France England Norway Finland Romania Ireland Scotland Italy and Wales This contribution presents an overview of the work associated with the importation of the parasitoids and the effort now being made to maintain genetic diversity Planned research is also discussed

The Impact

This essay contains personal observations and interpretations by the author on the persistence of pastures in the northern North Island. Key pasture stress factors are identified as the increase of farming intensity over the past two decades, the impact of pasture renewal techniques and the role of pasture species on insect pest (particularly black beetle and clover root weevil) interactions. Keywords: insect pests, soil fertility, pasture renewal, cultivars, endophyte

Listronotus Bonariensis

Although the role of the endophytic fungus Acremonium lolii in protecting the host plant from attack by insect pests, particularly Argentine stem weevil (Listronotus bonariensis), is often described in terms of plant resistance, it is a case of classical biological control. Endophytes in commercially available perennial ryegrass cultivars are acting as biological control agents against at least four pest species in New Zealand. Generally, endophyte adversely affects insect stages that feed on the above-ground parts of the plant, particularly those stages that feed near the base of the plant. It is apparent from insect feeding tests that there is no one universal anti-insect metabolite that will adversely affect all pest populations. It is therefore likely that an endophytelgrass combination that produces a cocktail of metabolites at low concentrations may be more useful than a combination that produces a very narrow suite of metabolites.
