it can be easily understood that the tasks alloted to entomology will be increas- 

 ed and will force the development of working places employed in the research 

 of these problems. 



The solving of practical tasks must be, of course, based upon a fundamental 

 theoretical research. Therefore, the perspective plan of the Czechoslovak 

 Academy of Sciences foresees the construction of an Entomological institute 

 A\ath about 40 scientific workers, to be completed between 1964—1966. It will 

 include the Entomological laboratory with all its present work teams and have 

 thus the following departments: developmental morphology, ecology, biocoeno- 

 logy, physiology and toxicology. The department of insect pathology will be 

 part of the future institute. The study of systematics and faunistic will be 

 concentrated in the enlarged entomological department of the National Museum. 

 Outside these institutions the basic entomological research will be contained 

 also in the programme of Universities and Polytechnical School laboratories. 



The present greatest problem is the absolute lack of the laboratory space 

 caused by a rapid growth of the institutes, especially in the Academy which 

 of course cannot be immediately supplied with new buildings. As for ento- 

 mology we shall be given a new building in the complex of the future Biolo- 

 gical Institutes in Praha-Krc the construction of which has been started 

 this year. 



The development of a scientific branch is not of course dependent exclusi- 

 vely on the staff and building. Most important are the quality and results 

 of work. In this respect we hope the development of entomology will proceed 

 according to the following principles: 



Entomology will develop intensively in all its branches, all the important 

 departments will grow proportionally. This will enable us to solve in complex 

 the different problems and facilitate the synthesis of the knowledge achieved. 

 Accordingly, beside the present traditional disciplines the development of ge- 

 neral entomology will be stimulated, such as ecology, biocoenology, develop- 

 mental morphology, physiology and toxicology. Special care wiU be paid 

 to the methodics. In theoretical research we intend to concentrate our forces 

 on the central theme: Study of the population dynamics of insects and of the 

 influencing biotic and abiotic factors. This is certainly one of the most import- 

 ant problems of theoretical entomology being in direct relation with question» 

 of practice. 



The problem will be solved from several points of view: ecology (influencing 

 the development, life time, fertility, seasonal periodicity by biotic and abio- 

 tic factors), biocoenology (study of the insect component of the biocoenoses 

 of cultivated areas, possibility of exterior influence), developmental morphology 

 (development and function of genital organs in relation to the fat body), 

 physiology (physiology of the insect development, diapause, metabolism etc.)
