New Acaricide for Citrus Mites

ChlorobenziIate--ethyl p, p’dichlorobenzilate-offers certain advantages in citrus pest control: it has a very low toxicity to warm-blooded animals which places it in the same category as Ovotran and Aramite; its application does not seriously affect insect parasites and predators or bees. Chlorobenzilate has a low order of toxicity to insects, therefore applications do not control populations o...

evaluation of some acaricide agents against hard ticks

two hundred and ninty four engorged female ticks were collected from 4 different geographical regions for assessment of tick resistance against acaricide compounds.the 15-21 day- old larvae have been tested in accordance with fao recommended larvae packet test .resistant factor for each region was calculated by lc50 and lc99. minimum lc50 (0.008)and, maximum lc50 (0.024) for amitraz were seen i...

Acaricide Residues in Beeswax and Honey

We studied the contamination level of the acaricides Folbex VA (bromopropylate, BP), Perizin (coumaphos, CM) Apistan (fluvalinate, FV) and Bayvarol (flumethrine, FM) in brood combs, sugar feed, honey and in new beeswax. All samples were analysed by gas chromatography with ECD detection. After one normal acaricide treatment, in autumn, the brood comb wax was contaminated by all these acaraicides...

An Empirical Evaluation of the 1986 Semiconductor Trade Arrangement

This paper aims to empirically evaluate the extent to which the 1986 Semiconductor Trade Arrangement (STA) affected the Japanese producers’ behavior and thus the evolution of the markets for the 256K and the 1M Dynamic Random Access Memory (DRAM) chips. We find that overall the STA facilitated the collusive behavior of the Japanese producers even beyond the myopic optimization: during the STA p...
