The impacts of weather on the damages caused by the lucerne seed chalcid (Bruchophagus roddi Guss.), the lucerne seed weevil (Tychius flavus Beck.), as well as by mirids (mainly Adelphocoris lineolatus Goeze, Lygus rugulipennis Popp., Polymerus vulneratus Panz.) and nutritional deficiencies manifested in shrivelled seeds were studied in Hungary. Data for the study were provided by examination of pod samples collected from 183 fields in 1964, regular collection of insects by sweep netting and… 

Geographic incidence and damage levels of alfalfa seed chalcid, Bruchophagus roddi (Hymenoptera, Eurytomidae), in Saskatchewan, and its relationship to weather and agronomic variables and production practices

Alfalfa seed chalcid infestation level was correlated most closely with the temperature and rainfall in July and August of both years, and the proportion of damaged seed was highest the year following warm, dry summers.

Attraction of Lygus rugulipennis and Adelphocoris lineolatus to synthetic floral odour compounds in field experiments in Hungary

By attracting both sexes of both species, these new attractants may prove to be useful and provide the basis for further development of new lures for agricultural use.

Investigation of Long-Range Female Sex Pheromone of the European Tarnished Plant Bug, Lygus rugulipennis: Chemical, Electrophysiological, and Field Studies

EAG dose–response studies showed that both males and females responded to these chemicals with minimal differences in sensitivity between the sexes or to the three components, except that males were more responsive than females to (E)-4-oxo-2-hexenal at the two highest doses tested.

Percussion signals of Lygus rugulipennis Poppius (Heteroptera: Miridae)

This is the first study on vibratory communication of the European tarnished plant bug and it is believed these findings may contribute considerably to the better understanding of the mating behavior of this important pest species.

The Use of Olfactory and Visual Cues in Host Choice by the Capsid Bugs Lygus rugulipennis Poppius and Liocoris tripustulatus Fabricius

Behaviour assessments conclude that the generalist L. rugulipennis has the ability to use remote olfactory cues for host choice whereas the specialist L. tripustulatus relies mainly on contact chemosensory and gustatory cues.

The Canadian Entomologist

A new species, Oeneis excubitor, is described that has male valvae similar to those of OeneIS melissa and Oenes jutta but the wing pattern is roughly similar to that of Oenes chryxus.



Dominance conditions and population dynamics of Lygus (Het., Miridae) species in Hungarian maize stands (1976–1985), as functions of climatic conditions

Population conditions and dynamics of three heteropteran species in Hungarian maize stands were studied by considering Selyaninov's hydrothermic quotient and as functions of the average temperatures of the given year.

Laboratory studies of the biology of the alfalfa seed chalcid, Bruchophagus roddi Guss. (Hymenoptera: Eurytomidae)

The alfalfa seed chalcid, Bruchophagus roddi Guss., a small jet-black wasp which infests Medicago, has caused alfalfa seed losses of up to 83 per cent in the western United States. Experiments

Field Infestation and Alfalfa Seed Chalcid (Hymenoptera: Eurytomidae) Development in Different Medicago Clones

Larval diapause appears to be induced in the female parent of the alfalfa seed chalcid and is probably dependent on factors affecting oviposition, and temperature, daylength, and resource competition affected field infestation levels and were associated with diapsause.

Alfalfa Crop Micrometeorology and Its Relation to Insect Pest Biology and Control

Micrometeorology of summer alfalfa in Phoenix, Ariz., and its relation to resident insect pests, particularly the beet armyworm, Spodoptera exigua (Hubner), is discussed. Solar and net radiation, air

Ecology: The Experimental Analysis of Distribution and Abundance

This book discusses ecosystem dynamics under Changing Climates, which includes community dynamics at the community level, and factors that limit Distributions, which limit the amount of variation in population size.

Action conjuguée des Hétéroptères Miridae et du déficit hydrique dans la malformation des graines de luzerne

On a étudié, dans les conditions of the pratique agricole and dans des parcelles expérimentales, l’action des punaises Miridae and du déficit hydrique sur the malformation des graines de luzerne sur la malformation oficiales de Lygus rugulipennis Popp.
