[Economic insects in Hawaii], H. P. Agee (Hawaii. Sugar Planters' Assoc. 

 Rpt. Expt. Sta. Committee, 1918, pp. 19-21).— This report includes a discussion 

 by Swezey of data relating to the efficiency of the introduced egg parasites of 

 the leaf hopper and by Swezey and Muir of foreign entomological work. 



It appears that when the H 109 variety of cane is affected by eye-spot 

 disease the leaf hoppers may have an increased preference for it, and the com- 

 bined attack of disease and insect is apt to be very severe. The Formosan egg 

 parasite Ootetrastlchns, introduced by Muir in 1916, greatly increased in 

 abundance during the year and gives promise of becoming a very valuable 

 introduction. A species of Entomophthora is reported to be quite beneficial 

 in checking the spread of leaf hoppers at Pepeekeo, as many as 19 hoppers 

 killed by this fungus having been found in a single leaf. The Anomala beetle 

 has become so well checked by Scotia manila, which was introduced from the 

 Philippines in I91f>-16, that no places are known where the cane is being 

 badly injured. This parasite is now found to be abundant in all the regions 

 occupied by the Anomala grubs and has even spread beyond the infested areas. 

 Brief mention is made of other parasites of the Anomala beetle, Dolichunu 

 siantoni which parasitizes the cockroaches Phyllodromia hicroglyphica and 

 Loboptera extranen, and of foreign work by the entomologists.
