The effect of the activities of these insects on the maize plants is 

 discussed. 



The greater part of the loss may be avoided at comparatively little 

 cost by the use of a poisoned bait consisting of 1 lb. sodium arsenite 

 or Paris green, 8 lb. crude sugar or 2 lb. molasses, to 10 gals, water. 

 A quantity of green vegetation should be chopped up finely, dipped in 

 the hquid, drained and distributed broadcast over the soil, particularly 

 towards evening, as most of the insects feed at night. The larvae of 

 wireworms are not, however, attracted by this bait, but the adult beetles 

 have been poisoned by it under favourable conditions. The bait should 

 be applied just before the appearance of the crop above ground, though 

 the weather must be taken into consideration, a favourable time being 

 an interlude after the first heavy showers have fallen. There is also 

 some benefit from baits laid any time between December and the 

 beginning of March, though the beetles at this time are sheltering 

 within the plants. It must not be expected that a single application 

 of bait will rid the land of these pests, and it must be remembered 

 that it is no remedy for such enemies as Busseola fusca or Heteronychus 

 mashunus (maize beetle).

A list is given of the commoner insect pests of 1918. Grasshoppers 

 were less numerous than in the previous year, and were kept in check 

 to a great extent by parasitic flies, Sarcophaga spp., and the energetic 

 efforts of the farmers. Those recorded include Camnula pellucida, 

 Scud., Melanoplus bivittatus, Say (two-striped locust) and Aulocara 

 elliotti, Thom. (big-headed grasshopper). 



Cutworms were very abundant during the year, especially Euxoa 

 ochrogaster, Gn., a species that cuts the plants off below the surface. 



Extensive damage was caused to the stems of young winter wheat 

 by a maggot found in May and subsequently identified as Hylemyia 

 cerealis, Gillette. 



Loxosiege sticticalis, L. (sugar-beet web-worm) caused great anxiety 

 owing to its presence in vast numbers, but no great damage was 

 done in spite of the fact that it is a very general feeder. 



The bug, Nysius ericae, Schill., was mainly injurious to garden plants. 



Details are given of the quarantine measures in force with regard to 

 Hypera variabilis {Phytonomus posticus) (alfalfa weevil).
