The number of <i>Septoria lycopersici</i> pycnospores necessary for inducing tomato infection was reported. In addition to this, the influence of inoculum concentration and site of tomato infection as well as the influence of air humidity and temperature on diseasee expression have been researched. Studies upon the character of <i>S. lycopersici</i> penetration and host-plant parasite interaction were made with the susceptible Bounty tomato under greenhouse conditions. The results of observations concerning the appearance and development of septoria leaf spot in the fields of central Poland were also described.

Dendrophthoe pentandra is a plant parasite that can be detrimental to the host plant and attacks various types of trees, such as acacia. The purpose of this study was to examine the effects and determine the concentration of acacia parasite filtrate on bagworms. This research was an experimental study which used 0%, 20%, 40%, 60%, 80%, and 100% parasite filtrate concentrations. The study employed the Completely Randomized Design method with ANOVA as the method of analysis. Based on the results of phytochemical tests, the parasite filtrate contained alkaloids, flavonoids, saponins, triterpenoids, phenolics, and tannins. The ANOVA test results showed that the concentration of acacia parasite filtrate affected the mortality of the bagworms. Furthermore, based on Duncan's test, the most effective concentrations to be applied were 80%, 60%, and 100%.

The new species, Bruchophagus ayadi sp.n., is reared from seed pods of Melilotus officinalis (L.) Desr. (Fabaceae) in Iran (Lorestan). The new species is close to B. platypterus (Walk.), but differs by roundish abdomen and very gibbous, almost globular (in lateral view) mesosoma. These species can be also differentiated by some biological features. The host plant of B. platypterus is Lotus corniculatus L., whereas the new species is reared from Melilotus officinalis (L.) Desr. Holotype of Bruchophagus ayadi sp.n. is deposited in the collection of I.I. Schmalhausen Institute of Zoology of National Academy of Sciences of Ukraine (Kyiv).
