Oxycarenus spp . s Rutherglen bugs 
Jarvis (46) in 1931 reported that Katakilla, 5 pounds per l r, 
imperial gallons of water, hilled 7C.2 percent of both adults and

Liridae 
Calocoris fulvomaculatus (Deg.) 
Calocori. norveg icus Gmel., a two-spotted green bug 
Van der Laan (55) in 1956 reported these species to be sensitive to 
derris dust. 
Pear trees infested T/ith C. fulvomaculatus yielded more fruit vh en 
dusted with derris (rotenone 1 or 2 percent) than when sprayed with 0.1 
percent of nicotine. --DeBussy et al. (6) in 1936. 
Dicyphus min imus uhl., the suckfly 
Excellent control '."."as obtained by dusting with derris-sulfur 
(0,5 percent rotenone) at the rate of 50 ocunds per acre, — Fentcn (26) 
in 1936. 
H alticus c itri (Ashm.), the garden flea hopper 
Chamberlin (ll) reported that during the 1933 growing season at 
Quincy, Fla. , a snail field of tobacco, very heavily infested with the

greater part of the growing season. I\o appreciable control could be 
observed. 
Helop el tis sp. 
Van der Scheer (75) in 1935 reported that a rctenone-benzene 
emulsion in water at s concentration of 1:5,000 rotenone gave good control. 
This species on tea r.av, perhaps, be controlled by ousts containing 
about 0.5 percent of rotenone. — Van der Vccht ('90 ) in 1935. 
He terocordylus malinus Rout., a dark apple redbug
