Anopheles maculipennis has been found infested with a species of 

 Hydrachnid (water mite), which was not present on A. bifurcatus, 

 Ciilex pipiens or Theobaldia annulata. The incidence of the mites is 

 evidently seasonal, the largest number occurring during September.

 Introduction of Nasonia brevicomis. — N. Z. J I. Agric. Wellington

A large consignment of Nasonia brevicomis, the parasite of sheep 

 maggot-flies, has been introduced into New Zealand for the purpose 

 of reducing the numbers of blow-flies, of which the chief are Pollenia 

 stygia and Lucilia sericata, and, in somewhat less numbers, Calliphora 

 erythrocephala, Chrysomyia {Pycnosoma) riififacies and Mtisca domestica. 

 An account is given of the hfe-history and habits of A^. brevicomis, 

 taken from the work of previous authors \R.A.E. B iii 15- vii'

A brief account is given of the results of mosquito investigations 

 of Herms and Freeborn in 1920 [R.A.E., B, ix, 66]. 



Observations indicate that the females of Anopheles quadrimacnlatits 

 occidental is hibernate approximately from mid-November to mid- 

 February ; no males are found during this time. The importance of 

 late autumn anti-mosquito measures is therefore evident. Owing to 

 the activities of local workers under the Mosquito Abatement Districts 

 Act of 1915 malaria has been reduced to a negligible factor in at least 

 one district. Mosquito surveys have been held, and the data tabulated. 



An mvestigation into the abundance of flies in and about poultry 

 farms has resulted in the installation of fly-tight bins and the periodic 

 collection of manure and garbage.
