FINAL SESSION 



In the final session of the symposium the following resolution was accepted: 



RESOLUTION 



The Symposium on the ontogenetic development of insects organized 

 in Prague from September 3 — 7, 1959, was attented by 208 scientific workers, 

 out of them 98 from abroad and 1 10 from the Czechoslovakia. 



The Symposium dealt with the following thematical groups: morphology 

 and anatomy of insect development, physiology of insect development, 

 seasonal periodicity of the development and influence of biotic and abiotic 

 factors on the development of insects. 



Totally 80 papers were read. Discussions took place at the end of each 

 report, in special discussion meetings as well as in many personal conversations. 



The scientific communications reflected the great progress achieved in all 

 special branches. In the work of the congress new problems emerged demand- 

 ing immediate solution, i. e. the questions concerning the functions of endocrine 

 organs (e. g. corpora allata) and their significance for the insect metabolism, 

 the manifestations and factors of diapause, biocoenoses of cultural plants, 

 population dynamics, fertihty etc. In future it will be necessary to pay more 

 attention to general disciplines of entomology, such as morphology, ecology 

 and physiology of insects. Important discoveries of the insect development 

 are of general biological interest and at the same time form the basis for the 

 entomological investigation aiming at practical solutions which were also 

 discussed at the symposium. 



The experience shows once more how important it is to meet specialists 

 from various countries and discuss with them current problems. It луоиИ 

 be very profitable for our work if these meetings could be organized regularly 

 in future. This proposal will be submitted to the International entomological 

 congress in Vienna for consideration; the symposia would thus become a regular 

 international institution .
