Groups of artificial nest tubes were deployed in the field for colonization by the accidentallyimported wasp, Ancistrocerus gazella (Panzer), a reported important predator of lepidopterous larvae, especially pest tortricids. There were 3-4 nest sites in each of seven study areas, and four tube lengths (75, 100, 125, 150 mm) were compared. Nests were dissected at various stages after occupancy to determine the prey composition and nest structure, and the numbers and sex of adults produced. The… 
Evaluation of the predatory wasp, Ancistrocerus gazella, for biological control of leafrollers in Otago fruit crops. II. Wasp phenology and seasonal changes in prey composition
TLDR
It was concluded that management of A. gazella for leafroller control would be uneconomic but it provides a useful component of the natural enemy complex of pest leafroller species.
Nesting behavior of Podium denticulatum Smith (Hymenoptera: Sphecidae).
TLDR
The nesting behavior of Podium denticulatum Smith was studied on the campus of Ribeirão Preto of the Universidade de São Paulo, SP, Brazil, from September 2003 to August 2005, producing at least five generations per year.
Trap-nesting Ancistrocerus sikhimensis (Hymenoptera: Eumenidae) IN NEPAL: nest structure and associates (Hymenoptera: Chrysididae; Acarina: Saproglyphidae)
TLDR
The contents of 21 trap-nests located in Sagarmatha National Park, Nepal, in 2002 and 2003 revealed interesting aspects of the biology of Ancistrocerus sikhimensis Bingham, and it is suspected that this species is bivoltine, with a highly shifted sex ratio between the two generations.
Aculeate Hymenoptera (Hymenoptera, Aculeata) Inhabiting Trap Nests in Crimea
TLDR
A strong correlation between the rate of colonization of trap nests and the amount of rains fallen at the beginning of the corresponding season in the given locality was observed.
Mutual and Opposing Responses of Carabid Beetles and Predatory Wasps to Local and Landscape Factors in Vineyards
TLDR
The results suggest that organic viticulture alone is insufficient to assist the studied insect groups, and that other local and landscape management options are needed for their protection.
Rain forest promotes trophic interactions and diversity of trap-nesting Hymenoptera in adjacent agroforestry.
TLDR
Diversity and parasitism are enhanced by (i) improved connectivity of agroecosystems with natural habitats such as agroforestry adjacent to rain forest and (ii) management practices to increase light availability in agroForestry, which also enhances richness of flowering plants in the understorey.
Artificial covering on trap nests improves the colonization of trap‐nesting wasps
TLDR
It is suggested that the covering technique could provide more opportunities for some wasp species to colonize trap nests because of the potential for increased parasitism between covered and uncovered traps.
The effects of cavity length on nest size, sex ratio and mortality of Centris (Heterocentris) analis (Hymenoptera, Apidae, Centridini)
TLDR
This study showed that an increase in the production of C. analis females can be achieved by increasing trap-nest length, and influenced the sex ratio of offspring, with male-biased sex ratios decreasing as the length of the trap-Nest increased.
Ecosystem services provided by aculeate wasps
TLDR
A first comprehensive review of how aculeate wasps contribute to the four main areas of ecosystem services: regulatory, provisioning, supporting and cultural services and a research roadmap identifying the key areas of research required to capitalise better on the services provided by these important insects.

TLDR
Ancistrocerus gazella (Panzer 1798) was found to prey almost exclusively on caterpillars of the lepidopterous family Tortricidae, which includes New Zealand's most damaging pests of fruit crops.
