摘要:

Two species of the cranefly genusTrimicraare recorded from the main islands of New Zealand in the latest catalogue (Oosterbroek 1989). One of these,T. pilipesFabr., is regarded as a highly variable cosmopolitan species with several subspecies. Evidence is presented here that New Zealand specimens previously considered to bepilipesactually represent at least three rather variable species (A, B, C), all of which occur sympatrically in the Manawatu region. Constant morphological features have been identified which distinguish the three forms. Species A is apparently conspecific with Europeanpilipes. Species B, which is widespread in New Zealand, has not yet been identified with any named species. Species C is identified withinconstansAlexander, a form which had been relegated to sub-specific status. The results of a mating preference study conducted with freshly captured, active specimens of all three forms suggest that interbreeding is unlikely.

摘要:

Stream invertebrates were collected from 24 sites surrounded by a mixture of native forest and pasture in the Mangaotama catchment near Hamilton, Waikato, between 1992 and 1999. Sampling methods used included Surber sampling for benthic invertebrates, pump sampling, freeze coring and colonisation baskets for hyporheic invertebrates, and light, sticky and Malaise trapping for winged adults.A total of 188 stream invertebrate taxa were identified during the course of this work, the greatest number reported for any catchment in New Zealand. Of these, 85% were insects comprising largely Trichoptera (68 taxa or 36%), followed by Diptera (40 taxa, 21%) and then Ephemeroptera (23 taxa, 12%). Light-trapping in summer on four occasions coupled with benthic sampling once in summer yielded 81% of total recorded taxa. Streams that drained catchments entirely in pasture or native forest had similar percentages of total invertebrate taxa, and of the Coleoptera, Diptera and Ephemeroptera faunas. However, native forest sites had lower percentages of Mollusca and “other” taxa, and more Trichoptera, Plecoptera and Crustacea taxa than pasture sites. Stream invertebrate distributional patterns in the Mangaotama catchment suggest changes in community composition and loss of some species adapted to forest cover in catchments converted entirely to pasture.

摘要:

The synonymy and usage of the various names that have been applied to the New Zealand colydiine beetleRytinotus squamulosusBroun are discussed. It is shown that most recent useage is based on a plethora of invalid names.The current and former distribution of the species and its probable biology are noted. A replacement name for the homonymEdalusBroun, 1893 (Tenebrionidae) is proposed.

摘要:

The symbiotic Hymenoptera associated with the Australian banyan figsFicus macrophyllaandF. rubiginosaand established in New Zealand are listed and keyed.Pseudidarnes minerva(Girault),Sycoscapter australis(Froggatt) andMegastigmussp. are new records for the N.Z. fauna.Pseudidarnes minervawas found to contain dimorphic males, and an uncommon apterous morph is described.

摘要:

Artona (Balataea) martiniEfetov 1997, a zygaenid moth recorded from Japan, China, Taiwan and Vietnam, was collected from seven locations, on bamboo, within the Whangarei district from March 1996 to April 1998. The moth has spread from the original site and is now found at distances of up to 10 km away. High numbers of the larvae may be present on host plants,Bambusa multiplex(Lour.),Shibataea kumasasa(Zoll.) Makino,Pleiobastus viridistriatus,Phyllostachys nigra(Lodd.) Munro, andMiscanthus sinensisAndersson. The larvae have not yet been recorded fromBambusa oldhamiiMunro, the most common bamboo species that is used as shelter in the local area. Urticating hairs on the larvae have produced skin irritation in some humans on contact. Adult moths have been observed mating on bamboo. Heavy infestations of the caterpillars at several sites in Whangarei during February 1999 indicate the species is now established in New Zealand.

摘要:

Primary types of 67 New Zealand species of Heteroptera (Enicocephalomorpha, Dipsocoromorpha and Cimicomorpha) described before the year 2000 and deposited in the New Zealand Arthropod Collection (Landcare Research, Auckland, New Zealand), are listed. Full label information and complete bibliographic references are given for each. A map indicating type localities and a list of types localities is given.

摘要:

A female lectotype is designated forDactylopius nipaeMaskell, which is presently placed in the genusNipaecoccusSulc. Other specimens from Maskell's type material ofD. nipaeare designated paralectotypes. Specimens studied are deposited in the New Zealand Arthropod Collection, Landcare Research, Auckland, New Zealand. Specimens from the type lot ofD. nipaethat are presently housed in institutions outside New Zealand were not examined in this study.

Three species ofParlatoriaare found in New Zealand:Parlatoria desolatorMcKenzie,P. fulleriMorrison and P. pittospori Maskell. Previous records ofP. pergandiiComstock andP. virescensMaskell from New Zealand are based on misidentifications ofP. desolator. The sole record ofP. ziziphi(Lucas) is based on a dubious quarantine record.

摘要:

The prey of the German wasp (Vespula germanica) were investigated by examining the loads carried by foragers caught in entrance traps as they returned to nests. A total of 3709 wasps were caught and 760 loads were examined from traps at four nests. Representatives of nine different orders made up 79% of those loads, showing thatV. germanicais a generalist predator in NW Patagonia. Spiders (Araneae), wasps and bees (Hymenoptera), caterpillars (Lepidoptera), beetles (Coleoptera) and flies (Diptera) were the most common prey items in the diet. The prey ofV. germanicain our study were broadly similar to those described for New Zealand and Chile. Arthropod prey consumption increased through the season whereas wood pulp consumption decreased. This fact reflects seasonal colony behaviour.

摘要:

Ladybird populations were assessed on citrus orchards in Northland, New Zealand, from January 1991 to February 1994. Ten-minute visual counts were made during all months and compared with manual searches of trees on three occasions.Halmus chalybeus(steelblue ladybird) comprised 97-99% of the ladybirds found by both types of assessment and was present throughout the year. Over 95% of the ladybirds recorded in visual counts were adults, whose numbers peaked in February-March. The most larvae and pupae were recorded in December-January.A manual search for ladybirds at an orchard near Kerikeri, Northland, in November 1991 recorded 153 ladybirds/tree with 91% comprising egg batches, larvae and pupae. Searches at a nearby orchard in December 1992 found 22 ladybirds/tree (71% immature) and 59/tree in February 1993 (5% immature). Visual counts of ladybirds recorded approximately 4-5% of the number of adult ladybirds found by manual searches, but only 0-3% of egg batches, larvae and pupae.Visual counting was a suitable method for estimating numbers of adult ladybirds on citrus orchards, but not immature stages.
