9. VERDANKUNGEN 



Prof. Dr. W. Sauter sei fur seine selbstlose Hilfsbereitschaft und konstruktive 

 Kritik vielmals gedankt, sowie Prof. Dr. P. Bovey fur die Uberlassung des 



' Dissertationsthemas und fur die Vermittlung bei verschiedenen Behôrden und 

 Prof. Dr. G. Benz fur dessen Ratschlàge bei den physiologischen Problemen. 



^ Dr. W. Buttiker bin ich fiir seine unermiidliche Unterstiitzung — speziell vvàhrend 

 meines Slidostasienaufenthaltes. der sonst kaum Fruchte getragen hâtte — 

 besonders dankbar. Der Thailândischen Regierung und der ETH danke ich fiir 

 jdie finanzielle Unterstiitzung durch Stipendien, dem Ministry of Education, 

 dem Ministry of Agriculture und dem Ministry of Public Health, Thailand. 

 fur ihren Beistand. Ferner bin ich zu dank verpflichtet : Prof. Dr. T. A. Freyvogel 

 (Vorschlag der Klistiermethode), Prof. Dr. H. Heusser und Dr. J. Nicolet 

 (veterinarische, bzw. mikrobiologische Problème). Dr. D. S. Fletcher (Bestimmung 

 der Lepidopteren) und ail jenen unzahligen thailândischen Bauern, die mir so 

 geduldig beistanden. 



SUMMARY 



1. Three groups of adult lachryphagous Lepidoptera are distinguished: i) those 

 which feed exclusiveh upon lachrymal sécrétion (eulachryphagous). ii) those 

 which feed often upon it (hemilachryphagous) and iii) those which feed only 

 occasionally upon it (oligolachryphagous). The latter groups also imbibe 

 fluids such as skin sécrétions (perspiration, sébum), blood (from open wounds 

 or as anal exudate of mosquitoes), the decomposed mixture of sodden earth 

 with urine and dung, and nectar, either directly on the host or indirectly 

 from the végétation where they have been left by the hosts. 



2. Faunistics. 20 Geometrids, 14 Pyralids, 2 Noctuids and I Notodontid were 

 found to be lachryphagous species; 26 of the above were not known as such. 

 25 further species are suspected to be lachryphagous, whereas a large number 

 of species associated with lachryphagous moths do not suck lachrymal fluid 

 but the mentioned skin sécrétions, excrétions and/or blood. 



3. Fn the area of study lachryphagous moths were found only near or within 

 forests and are distributed mainly in tropical monsoon régions and less in 

 the permanently humid régions. Lohocraspis griseifusa (eulachryphagous) 

 may be found during any season while non-eulachryphagous moths are 

 scarce during the dry season.
