Abstract: A device and a method for locating and counting insects in agricultural commodities has been developed. Acoustic sensors pick up sounds emanating from adult and or larval insects. The electrical outputs of the sensors are amplified and analyzed to determine (1) the first sensor to detect the sound, (2) the second sensor to detect the sound and (3) the time difference between the first and second detection. These determinations are used to calculate the locations and numbers of insects in the agricultural commodity samples.

Abstract: A serotype 2 Marek's disease vaccine comprising a cloned strain designated as 301B/1 has been derived from a field isolate. This strain is characterized by superior levels of replicative ability and protectivity in chickens as compared to existing commercial serotype 2 strains, and it is virtually nonpathogenic. 301B/1 is particularly useful in the formulation of highly efficacious bivalent and polyvalent vaccines.

Abstract: A Marek's disease vaccine comprising either a revertant virus derived by backpassaging an attenuated serotype 1 Md11 virus or an antigenic component of the virus is characterized by increased levels of replicative ability and protectivity in chickens as compared to the original attenuated strain. Revertants of the invention are exemplified by a clone identified as Md11/75C/R2 and can be formulated into monovalent and polyvalent vaccines.

Abstract: The oral administration of boron compounds such as sodium borate and boric acid increases the amounts of hydroxylated steroids in human plasma. This will help prevent or alleviate pathology, such as osteoporosis, caused by suboptimal circulating hydroxylated steroids such as 17.beta.-estradiol and testosterone.
