The nesting of Passaloecus pictus Ribaut, 1952 was observed in Kowalewo Pomorskie (northern Poland). The nests were built in trap nests that were placed on a windowsill facing southwest. The females used resin from Picea pungens Engelm., located 5 m away, to build the cell walls. The tunnel consisted of 1–7 cells. The females provided provisions fo...

Honeydew extracted by aphids serves as nutrient for the development of sooty moulds. Hypothetically, population dynamics of aphids should therefore have an effect on the airborne levels of the spores of fungi colonizing honeydew. In this study, the effects of seven aphid taxa on Alternaria and Cladosporium spore seasons (both pathogenic and allerge...

The main aim of the study was to become acquainted with the daily and seasonal dynamics of flights of ten economically important aphid species in Johnson’s suction trap in Winna Góra in 2018–2020. In the 2018 a total of 3.584 winged aphid specimens were caught, in 2019 – 5.049, and in 2020 – 9.411. Five aphid species were noticed as the most numero...

The aim of the research was to determine the influence of acetamiprid and deltamethrin on the mortality and behaviour of honeybees of the same variety, coming from the same source and estimated to be in good condition by a professional beekeeper, but in different years and under different weather conditions. Results of research conducted in field i...

Od dnia 1 stycznia 2014 r. na mocy Dyrektywy Parlamentu Europejskiego i Rady 2009/128/WE z dnia 21 października 2009 r. ustanawiającej ramy wspólnotowego działania na rzecz zrównoważonego stosowania pestycydów, na terenie Rzeczpospolitej Polskiej, obowiązuje przestrzeganie zasad integrowanej ochrony roślin przez wszystkich profesjonalnych użytkowni...

The temperature, photoperiod and nutritional quality of hostplants are the main factors affecting the emergence of sexual forms of aphids. Under certain conditions they can induce changes in the biology of aphids, which so far exhibited holocyclic development, for instance the peach-potato aphid (Myzus persicae Sulzer, 1776). Among the economically...

A compendium of knowledge about pests of agricultural plants

In 1973–2011 in Poznań, aphid catches were carried out using Johnson's suction trap. Since then the suction trap located at the Institute of Plant Protection – National Research Institute in Poznań has continuously recorded the daily and seasonal dynamics of aphid flights. The collected results has been used to establish one of the largest database...

Lupin plants are frequently damaged by various herbivorous invertebrates. Significant among these are slugs and aphids, which sometimes attack the same plants. Relationships between aphids, slugs and food plant are very interesting. Grazing by these pests on young plants can lead to significant yield losses. There is evidence that the alkaloids pre...

Bird cherry-oat aphid (Rhopalosiphum padi L.) is the most abundant aphid species on cereals in Poland. It represents approximately 80% of all cereal aphids. Its anholocyclic forms are the most important vectors of Barley yellow dwarf virus (BYDV). These forms are new among the Polish population of R. padi. Their changes in development are the resul...

So far in Poland 7 aphid species developing only holocyclically have been observed on maize. Observations which were carried out in the Wielkopolska region in 2004–2012 revealed an occurrence of 5 aphid species. For the first time, in 2012, anholocyclic development of all the observed aphid species was recorded. Among them, new host races of Rhopal...

The aim of the study was to assess the dynamics of number of the pea aphid on selected varieties of pea and faba bean. The experiment was conducted in a climate chamber in the Institute of Plant Protection – National Research Institute in Poznań, under controlled conditions (constant temperature, humidity and photoperiod), with ten replications. Fi...

The dynamics of the occurrence of pea leaf weevil (Sitona lineatus L.) on pea and faba bean crops on selected localities in Wielkopolska Dynamika występowania oprzędzika pręgowanego (Sitona lineatus L.) na uprawach grochu siewnego i bobiku na wybranych stanowiskach w Wielkopolsce Przemysław Strażyński Summary The aim of the study was to assess the...

Evaluation of selected varieties of yellow lupine and narrow-leaf lupine for colonization by aphids Ocena podatności wybranych odmian łubinu żółtego i wąskolistnego na zasiedlanie przez mszyce Summary The field experiments were conducted at the Experimental Station of Variety Evaluation at Głodowo that belongs to Research Centre for Cultivar Testin...

Rhopalosiphum padi L. aphids on cereals show extensive changeability, in terms of an increased presence, diversity of forms and species as well as times of occurrence. A significant increase in the area of maize crops in Poland along with temporarily higher temperatures have significantly affects aphid ecology on all cereals. Large cereal crop area...

Viteus vitifoliae (Fitch, 1885) a new species of aphid in Poland (Hemiptera: Aphidomorpha: Phylloxeridae) The grape phylloxera [ Viteus vitifoliae (Fitch, 1855)] is reported in the Polish fauna for the first time. Adult females and galls are described, and information on its biology and distribution is summarized and commented on.

Evaluation of The Autumn Infection of Winter Barley with Barley Yellow Dwarf Viruses Transmitted by Anholocyclic forms of Bird Cherry-Oat Aphid Rhopalosiphum Padi L. in Poland Research was carried out to determine the extent of anholocyclic forms of bird cherry-oat aphid, Rhopalosiphum padi on winter barley, and to estimate the level of infection o...

Johnson’s suction trap located at the Institute of Plant Protection–National Research Institute in Poznan is used for aphid monitoring since 1973. Daily catches of insects allowed to keep trace of the intensity of and time each species flights. This is particularly important for precise determining threat, primarily by aphids – viruses vectors, and...

The development of aphids is largely dependent on the temperature range. Temperature influences aphids both directly and indirectly through host plants. An example of a direct influence of temperature on aphid development is an increasing Rhopalosiphum padi L. population. An indirect influence of temperature on aphids is presented on the example of...

Trixagus atticus REITT. (Coleoptera: Throscidae) is reported as new to the Polish fauna. One male of this species was caught in Poznań. A checklist for Throscidae of central Europe and Poland is given.

The bird cherry-oat aphid (Rhopalosiphum padi L.) development on primary host (Prunus padus L.) was studied in Poznan in 2007–2008. First fundatrices of R. padi were observed already on the bird cherry in March in both years. The largest condensation of population was observed in May. At the second decade of May numerous winged morphs were formed a...

Rhopalosiphum padi (Linnaeus, 1758) is a dominating species in the population of all cereal aphids in Poland, and its anholocyclic forms are major cereal virus vectors, especially BYDV. Global warming which stimulates the development of aphids-virus vectors is highly important in the spreading of anholocyclic forms of R. padi and cereal viruses. BY...

The BYDV infection is a new problem in cereal protection in Poland. This disease is exclusively transmitted by aphids and the most important vectors are anholocyclic forms of Rhopalosiphum padi L. The forms are new in the Polish population of this species and they develop as an effect of global warming. The important factors in prophylactic in cere...

Wszystkie gatunki mszyc szkodzą roślinie bezpośrednio wysysając soki, wskutek czego zakłócona zostaje fizjologia rośliny, a powstałe podczas uszkodzenia mogą stać się powodem wtórnych infekcji grzybowych lub bakteryjnych. Jednak o wiele groźniejsza jest szkodliwość pośrednia mszyc – zdolność do przenoszenia wirusów. Dlatego bardzo ważną rolę w ochr...
