Approximately 30 exotic ant species have been introduced into New Zealand, including the Argentine ant Linepithema humile (Mayr). Many of these ant species are known to affect horticulture worldwide by tending hemipteran insects. These ants may protect these hemiptera from their natural enemies, resulting in higher pest densities and potential economic loss. Our aim in this work was to survey the ant species associated with the various horticultural crops in the North Island. Our focus was on L. humile, but we also collected other ants and associated hemipteran species. Linepithema humile appeared to be an opportunistic species and was found on fifteen of eighteen common horticultural crops that we surveyed, as well as on a variety of other plants. It was observed tending 15 different species of hemipteran insects. Linepithema humile has been previously observed tending some of these hemipteran insects overseas, such as the black scale Saissetia oleae (Olivier). Other observed L. humile-hemipteran-plant associations reported here have not previously been recorded, such as with the spirea aphid Aphis spiraecola Patch on plum trees. Eleven other species of ants were found on horticultural crops. Paratrechina vaga (Forel) was common and also tended hemipteran insects on apple, citrus, and tamarillo. Other common ants were Tetramorium grassii Emery, Monomorium antarcticum (Smith), Pheidole rugosula Forel and Ph. vigilans (Smith). Another adventive ant, Ph. megacephala (Fab.), was only sampled in Auckland despite having been in New Zealand for over 50 years. Many of these invasive ants thus do not appear threatening to horticultural crops, though L. humile appears likely to be a significant economic pest for a variety of crops.
