Host-Plant Selection and Predation Risk for Offspring of the Parent Bug

1995

Herbivores, especially specialists, must adapt to characteristics of their host to survive and reproduce successfully (Hardin and Tallamy1992). If offspring survival among different hosts varies, natural selection should lead females to choose egg-laying sites where performance of the progeny will be highest. This is especially true when newly hatched larvae cannot move to another host (Singer 1986), or when searching for new hosts would cause heavy mortality (Singer and Mandracchia 1982). A number of studies have shown that females that search for oviposition sites respond to plant characteristics that are correlated with the nutritional quality of plants for their offspring (e.g., Myers 1…

Pierwsze stanowisko Aradus brevicollis FALLÉN, 1807 oraz drugie Aneurus avenius (DUFOUR, 1833) (Heteroptera: Aradidae) w Beskidach Wschodnich

Nowe stanowiska korowcowatych (Hemiptera: Heteroptera: Aradidae) w Polsce

2016

New faunistic data on the occurrence of flat-bugs Aradidae in Poland are presented. Data concerning a total of 13 species of flat-bugs are presented, including five species very rarely collected in Poland: Aradus bimaculatus, A. brevicollis, A. erosus, A. truncatus and Mezira tremulae. The distributional data relating to rarely collected species and information about their biology is reviewed.

Contrasting reproductive traits of competing parasitoids facilitate coexistence on a shared host pest in a biological control perspective

2022

BACKGROUND: Interspecific competition in insect parasitoids is an important ecological phenomenon that has relevant implications for biological pest control. To date, interspecific intrinsic (=larval) competition has been intensively studied, while investigations on extrinsic (=adult) competition have often lagged behind. In this study we examined the role played by parasitoid reproductive traits and host clutch size on the outcome of extrinsic competition between Trissolcus basalis (Wollaston) and Ooencyrtus telenomicida (Vassiliev), two egg parasitoids of the pest Nezara viridula (L). Laboratory experiments were conducted by allowing both parasitoid species to exploit an egg mass made of …

Pierwsze stwierdzenie długoskrzydłego okazu Prostemma aeneicolle Stein, 1857 (Hemiptera: Heteroptera: Nabidae) na Dolnym Śląsku

2021

[The first discovery of the long-winged Prostemma aeneicolle Stein, 1857 (Hemiptera: Heteroptera: Nabidae) specimen in Lower Silesia]. Prostemma aeneicolle occurs most often as a short-winged specimen, and long-winged individuals are infre-quent. Such a specimen was found for the second time in Poland and for the first time in Lower Silesia. The first occurrence of this species in Opole was also reported.

Plant surfaces of vegetable crops mediate interactions between chemical footprints of true bugs and their egg parasitoids.

2009

During the host location process, egg parasitoids can eavesdrop on chemical cues released from immature and adult hosts. These indirect host-related cues are highly detectable, but of low reliability because they lead egg parasitoid females to an area where oviposition is likely to occur rather then providing wasps with direct information on the presence of eggs and their location. In the host-parasitoid associations between true bugs and their scelionid egg parasitoids, female wasps perceive the chemical residues left by host adults walking on substrates as contact kairomones, displaying a characteristic arrestment posture. In this study, we demonstrated that epicuticular waxes of leaves o…

Two new genera and species of the Fulviini (Hemiptera, Heteroptera, Miridae, Cylapinae) from Madagascar, with a checklist of Madagascan cylapines

2022

Two new genera, each represented by a single new species, Cassisotropis aciformis Taszakowski et al. gen. et sp. nov. and Infernotropis madagascariensis Taszakowski et al. gen. et sp. nov. are described from Madagascar. Photographs and SEM micrographs of the male and female habitus, genital structures and selected morphological structures are presented. The first record of Fulvius anthocoroides (Reuter, 1875) in Madagascar and the checklist of Madagascan cylapines are also provided.
