The tarnished plant bug, Lygus lineolaris (P. de B.), is the dominant mirid in crops grown in eastern North America (Strong 1968; Bariola 1969). Lygus lineolaris is an ubiquitous species found on a wide range of wild plants and cultivated crops (Knight 1941).All previously known egg parasitoids of Lygus spp. were mymarids in the genera Anaphes, Erythmelus, and Polynema (CIBC 1979). The mymarid Anaphes iole Girault is the principal egg parasitoid of Lygus spp. in the United States (Debolt 1987). It has been reported from British Columbia, Alberta, Ontario, Quebec, and the Northwest Territories(Huber and Rajakulendran 1988).

AbstractThe seasonal occurrence of four species of egg parasitoids of the tarnished plant bug (Lygus lineolaris) was determined in three different habitais: fields of mixed weeds. alfalfa (Medicago sativa L.). and crown vetch (Coronilla varia L.) in southwestern Quebec in 1991 and 1992. Parasitoids studied were the mymarids Anaphes iole Girault, Polynema pratensiphagum (Walley), and Erythmelus miridiphagus Dozier and a scelionid, Telenomus sp. Adult populations of these parasitoids showed three or four population peaks in all habitats throughout the season. Adult parasitoid activity started during the first egg-laying period of L. lineolaris at a temperature accumulation of 73 degree-days (DD). The overwintering period began in mid-October at 1277 and 1058 DD for 1991 and 1992, respectively. All the parasitoids had a strong synchrony with L. lineolaris populations; specifically, marked peaks in the adult population of all species were in synchrony with the egg-laying periods of L. lineolaris.

Anaphes iole Girault is a native, solitary egg parasitoid of Lygus bugs in North America. Ongoing research is considering factors that may lead to efficient mass rearing of A. iole for augmentative biological control. This study examined the effects of A. iole female density and arena size on progeny production. Production increased by a factor of 2.1 as parasitoid density increased from 5 to 10 and from 10 to 20 females per 8 Larena (rearing cage) with a host patch containing from 1,500 to 2,000 eggs of Lygus hesperus Knight (Heteroptera: Miridae). Sex ratios of mature progeny did not differ significantly between parasitoid densities of 10 versus 20 females. Arena size (≈1, 2, 4, or 8 L cages) had no effect on progeny production when 20 females were confined to the same cage. This research suggests that little or no measurable interference will occur between ovipositing A. iole females on shared host patches and cage size can be varied to increase rearing capacity.

First Time

Acroclisoides sinicus (Hymenoptera: Pteromalidae) was described in 1988 from China, but recent findings in Europe and North America within the framework of Halyomorpha halys (Hemiptera: Pentatomidae) biological control indicate a Holarctic distribution. The few records and fragmented information on A. sinicus are derived from generic observations of other species belonging to the same genus, and its biological and ethological traits are still completely unexplored. It was suspected to be a facultative or obligate hyperparasitoid of many egg parasitoid species (e.g., Scelionidae and Eupelmidae), especially those parasitizing Pentatomidae eggs. Laboratory colonies of A. sinicus were established from specimens collected in the field in Europe and the USA, which allowed us to investigate for the first time the life traits of this somewhat enigmatic species. Our studies confirmed the obligate hyperparasitoid hypothesis for species of Scelionidae but not of Eupelmidae. Laboratory studies revealed that A. sinicus is extremely selective in its host recognition as only the pupal stage of its host species is exploited for parasitization. Taking into consideration its hyperparasitoid habit, the adventive A. sinicus populations in Europe and North America may potentially be severe threats to pentatomid natural control as new components in the trophic chain of pentatomids and their parasitoid guilds.
