EssiG (E. 0.). The Ontario Mealy Bug {Pseudococcus sp.) — Mthh/. 

 Bull. State Comm. Hortic, Sacramento, iv, no. 7, July 1915, pp. 343- 

 344, 1 fig. 



The mealy bug infesting the citrus orchards at Uplands and generally 

 known as the " Ontario mealy bug " was first believed to be Pseudo- 

 coccus bal'eri, Essig, and was reported as such by the author in January 

 in the report to the Mealy Bug Convention at Ontario, California. 

 Since then he has formed the opinion that it is either a new species 

 or an imported species from some other country. In April, an infesta- 

 tion was discovered on Lauras nobilis (bay) from Holland in a Japanese 

 nursery in Oakland and this would also indicate that the insect was 

 imported from Holland, inasmuch as none of the plants from Japan 

 were observed to be infested.

A Melolonthid, Phobetus comatus, Lee, has been reported as 

 seriously injuring the foliage of cherry, plum and peach trees during 

 the past month. A Dipterous maggot, probably the larva of 

 ChortojjJiila (Phorbia) fusciceps, Zett., was reported frequently in the 

 spring of 1915, attacking green onions near San Francisco. Pohjcaon 

 confertus, Lee (olive twig borer) has been abundant in Sacrameuto 

 county and has injured avocados and young citrus trees in Ventura 

 county where a species of Serica is reported as doing much damage to, 

 Ahuacate trees. The larvae of Atherigona sp., a fruit and vegetable 

 infesting Anthomyid, has been intercepted iii quarantine from Florida. 

 Trichogramma minutum, Riley {preliosa, Riley), has been reared from the 

 eggs of the codling moth during the past month. Adults of the 

 Galerucid, Luperodes bivittatus, Lee, have been riddling the leaves of the 

 young peach trees in Sacramento county. Serica alternata, Lee, has 

 been common in Ventura county and has damaged the foliage of fruit 

 trees to some extent. Limonius californicus, Mann. (California wire 

 worm), is damaging truck crops near Sacramento. The cutworm, Agrotis 

 ypsilon, Rott., was so destructive to garden crops in Sacramento in 

 the spring of 1915 that in many cases replanting was necessary. 

 Gastroidea cyanea, Melsh. (green dock beetle), was very common on 

 dock. Extensive measures have been carried out in Stockton against 

 Gossyparia spuria, Mod. {ulmi, L.). Rosebuds are suffering much 

 damage from the attack of Rhgnchites bicolor, F. (rose snout-beetle). 

 Hoplia pubicollis, Lee, was collected in great quantities in Placer 

 county. About one hundred pounds weight of Hippodamia convergens, 

 Gu^r., was collected in the high Sierras during mid- June.
