Development of Non-chemical Alternative Treatments for Horticultural Pests of Quarantine Significance (Methyl Bromide Alternatives)Entry ID: USDA0523
Abstract: "Development of Non-chemical Alternative Treatments for
Horticultural Pests of Quarantine Significance (Methyl Bromide
Alternatives)" contains research data with the purpose of
developing effective non-chemical quarantine treatments for
subtropical fruits, vegetables, and ornamental flowers infested
or attacked by fruit flies, sweet potato weevils, or other pests
of quarantine importance.
... Collection Organization: USDA Agricultural Research Service
Collection Methodology: Alternative quarantine treatments for
methyl bromide fumigation are being tested to disinfest
commodities of pests. Gamma radiation with 150 gray from a
cobalt 60 source provides quarantine security against eggs and
larvae of sweet potato weevils in sweet potato roots. Doses at
150 gray and 180 gray sexually sterilize males and females,
respectively. A dose between 250-400 gray will provide
quarantine security and prevent development of blueberry
maggots. Preliminary results suggested it might be possible to
sterilize all plum curculio life stages with 160 Gy. Ohmic
heating of fruits showed that the interior of a fruit could be
heated to a higher temperature than the surface. The combination
of coating plus 300 ppm dimethoate gave 93-98% less survivors
than either coating or dimethoate alone.
