In support of a biological control program in California, USA, against the bagrada bug, Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae), an invasive pest of Asian origin, colonies of two species of Ooencyrtus Ashmead (Hymenoptera, Encyrtidae) are maintained using B. hilaris eggs as host. One of them, Ooencyrtus mirus Triapitsyn & Power, sp. nov., is of Pakistani origin. It displays natural preference for bagrada bug eggs and is being evaluated in quarantine as a candidate for classical… 
Preferential Parasitism of Ooencyrtus mirus (Hymenoptera: Encyrtidae) on Bagrada hilaris (Hemiptera: Pentatomidae) Regardless of Rearing Host
Results show that O. mirus prefers eggs of its primary host, B. hilaris, for oviposition over the alternate hosts tested regardless of whether the parasitoids were reared on the primary or alternate hosts.
Adventive Gryon aetherium Talamas (Hymenoptera, Scelionidae) associated with eggs of Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae) in the USA
This report marks the first known record of G. aetherium in the USA, and further work should be conducted to assess the potential of this parasitoid for biological control of B. hilaris.
Evaluation of the Physiological Host Range for the Parasitoid Ooencyrtus mirus, a Potential Biocontrol Agent of Bagrada hilaris
The results show O. mirus to be a generalist parasitoid species with a preference for B. hilaris, and there is a linear relationship between the mean body length of O.mirus females and the mean host egg weight.
Native and Non-Native Egg Parasitoids Associated with Brown Marmorated Stink Bug (Halyomorpha halys [Stål, 1855]; Hemiptera: Pentatomidae) in Western Slovenia
Overall parasitism rates of naturally laid eggs by the parasitoid species complex in 2019 and 2020 was 3.0 and 14.4%, respectively, which are very encouraging results, which need to be followed and verified in future research.
Effects of Parasitoid Age, Host Egg Age, and Host Egg Freezing on Reproductive Success of Ooencyrtus mirus (Hymenoptera: Encyrtidae) on Bagrada hilaris (Hemiptera: Pentatomidae) Eggs
A factorial design to evaluate all combinations of host egg ages 0–5 d and parasitoid age, and reproductive success showed that the best combinations are 0- to 1-d-old host eggs with 3- to 10-D-old parasitoids.
A novel approach for the biological control of invasive Bagrada bugs with entomopathogenic nematodes
In a semifield study, a single application of this EPN with an adjuvant achieved approximately 60% mortality of the bugs after 480 h on rocket plants, and the damage to leaves was significantly lower (29%) than thedamage to leaves of control plants (54.3%).
Effect of Temperature on the Survival and Developmental Rate of Immature Ooencyrtus mirus (Hymenoptera: Encyrtidae)
Results show 36°C to be the best temperature for rearing O. mirus, and that Ooencyrtus mirus-parasitized eggs can be stored at 14°C for months without losing viability, crucial data to consider when mass rearing this biological control agent.
Preempting the Arrival of the Brown Marmorated Stink Bug, Halyomorpha halys: Biological Control Options for Australia
Biological control is one of the few control options for this species and will be important for managing H. halys should it become established in Australia, and prioritizes potential biological control agents that could be suitable for use in Australia.
Life History Evaluation of Ooencyrtus lucidus, a Newly Described Egg Parasitoid of Bagrada hilaris
Ooencyrtus lucidus has sufficient life history traits to make it a promising egg parasitoid for the biological control of B. hilaris, and providing females with host eggs in addition to honey, reduced their longevity by 24% in mated and 28% in non-mated individuals.
First report and integrated analysis of two native Trissolcus species utilizing Bagrada hilaris eggs in California
Molecular and morphological analysis of sentinel eggs of Bagrada hilaris retrieved two parasitoids that were not previously known to be associated with this stink bug, and an updated couplet is provided to separate T. utahensis from a morphologically similar species, T. cosmopeplae.


Diversity of Ooencyrtus spp. (Hymenoptera: Encyrtidae) parasitizing the eggs of Stenozygum coloratum (Klug) (Hemiptera: Pentatomidae) with description of two new species
Ooencyrtus spp. (Hymenoptera, Chalcidoidea, Encyrtidae) are important natural enemies of agricultural and forest insect pests, and are distributed worldwide. Their reduced dimensions, highly variable
Trissolcus hyalinipennis Rajmohana & Narendran (Hymenoptera, Scelionidae), a parasitoid of Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae), emerges in North America
A survey of resident egg parasitoids using fresh sentinel B. hilaris eggs in Riverside, California, revealed that T. hyalinipennis is present in the wild, and it is presumed that the introduction to this area was accidental.
First Report of the Invasive Stink Bug Bagrada hilaris (Burmeister) (Heteroptera: Pentatomidae) from New Mexico, with Notes on its Biology
The current distribution of B. hilaris in New Mexico and notes on its hosts and biology are presented.
On the origin of Anagyrus callidus (Hymenoptera: Encyrtidae), a parasitoid of pink hibiscus mealybug Maconellicoccus hirsutus (Hemiptera: Pseudococcidae).
The origin of A. callidus is shown to be from Taiwan, based on differences in the morphology and molecular sequences of voucher specimens of an earlier colony of the misidentified A. kamali from Puerto Rico, and specimens that originated in southern Taiwan.
Ooencyrtus (Hymenoptera: Encyrtidae), egg parasitoids of the pistachio green stink bugs (Hemiptera: Pentatomidae) in Iran.
Three species of Ooencyrtus Ashmead obtained from eggs of the green stink bug, Brachynema germarii (Kolenati) infesting pistachio plants in Iran are dealt with.
Egg parasitoids from Pakistan as possible classical biological control agents of the invasive pest Bagrada hilaris (Heteroptera: Pentatomidae).
A classical biological control project was initiated in 2014 to discover and import key natural enemies within the area of origin of B. hilaris for quarantine evaluation in the United States, and this is a report on initial results.
Expanding the Anagyrus pseudococci species complex (Hymenoptera: Encyrtidae): a new species emerges from Trabutina serpentina (Hemiptera: Pseudococcidae) on tamarisk on the Dead Sea shore
