extrrctable metabolites tentatively identified were: 1-naphthol; l-hydroxy-5, 

 6-dihydro-5, 6-dihydroxy-naphthalene; 5, 6-dihydro-5, 6-dihydroxy-l-naphthyl 

 N-methylcarbamate; and 1-naphthyl N-hydroxymethylcarbamate, Unknown meta- 

 bolites of a water-soluble nature were predominant in both insect species.

 tial parasite of the boll weevil. Indian J. Entomol. 26: 447-452. 



Bracon greeni Ashmead is an important parasite of certain pod-boring Lepidop- 

 tera in the Indian sub-continent, but attempts to introduce it into the 

 United States between 1952-1937 as a natural control of the pink bollworm, 

 Pectinophora gossypiella (Saunders), failed, possibly because of the diffi- 

 culty encountered in breeding the parasite under laboratory conditions. As 

 a result of evidence obtained in India that the parasite would accept a 

 coleopterous host, tests were conducted at Moorestown, New Jersey, to 

 determine whether the parasite would accept the boll weevil, Anthonomus 

 grandis Boheman, as a host. These tests were successful. When last stage 

 boll weevil larvae were used, some healthy F2 adult B^. greeni were obtaiiied. 

 Larvae of 5 other insects, also tested as hosts at Moorestown, were ignored 

 by B^. greeni .

 lations of malathion and azinphosmethyl applied by airplane. J. Econ. 

 Entomol. 61: 1015-1020. 



Deposits of undiluted technical formulations and water-diluted emulsifiable 

 concentrates of malathion and azinphosmethyl applied by airplane were analyzed 

 by chemical methods and by bioassay. The insecticides were detected under 

 adverst: conditions as far as 800 m (1/2 mile) downwind from the line of 

 *" application. Estimated recoveries from the treated swaths and from the 

 adjacent area into which the spray drifted ranged from 18 to 96% of the
