“…Hayat (2009) firstly described this species as Aenasius bambawalei Hayat and A. bambawalei was determined a junior synonym of A. arizonensis by Fallazadeh et al (2014). This solitary nymphal-adult endoparasitoid (Rathee et al, 2015) was also first reported in Turkey in 2018 (Çalışkan-Keçe et al, 2018). Some of the biological characteristics and parasitism potential of A. arizonensis have been studied by foreign researchers (Vijaya, 2011;Rathee and Ram, 2014;Rathee et al, 2015;Vijaya and Singh, 2018).…”

Aenasius arizonensis (Girault) (Hymenoptera: Encyrtidae) is the primary parasitoid of Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae). Some biological parameters of this parasitoid have not been fully understood. Therefore, this study was conducted to determine biological parameters of A.arizonensis at 25 °C, 65% R.H, 16 : 8 L : D with Age-stage Two-sex life table and effectiveness of this parasitoid in field conditions in Turkey. The results showed that pre-oviposition, oviposition and post-oviposition periods of A. arizonensis were calculated as 1.5, 26, and 3.1days, respectively. In addition, total mean longevity was determined as 31 days for female, and 18 days for male individuals. Moreover, total mean fecundity and daily mean fecundity were also found as 83 mealybugs/female, and 4.1 mealybugs/female/day, respectively. The intrinsic rate of increase (r), net reproduction rate (R 0 ), finite rate of increase (λ), gross reproductive rate (GRR), and mean generation time (T) were found 2 0.135, 41.25, 1.144, 60.90, and 27.57, respectively. Field studies have been conducted to determine the efficacy of this parasitoid in 2018 in Adana and Mersin / Turkey. The parasitism rate was risen to 78 -80% in September, both in Adana and Mersin provinces, attributed to early releases in August, 2018. In conclusion, higher parasitism rates showed that this parasitoid can be successfully used against cotton mealybug as an effective biological control agent.

“…Traditionally, most studies related to insect storage at low temperature have been focused on biocontrol agents (parasitoids and predators), especially Hymenoptera (Jayanth & Nagarkatti, 1985;Jalali & Singh, 1992;Bernardo et al, 2008;Rathee & Ram, 2014) and, less frequently, Diptera (Easwaramoorthy et al, 2000;Benelli et al, 2017;Rathee & Ram, 2018). Few studies have paid attention to the cold storage of pollinators, most of them focused on the overwintering of Hymenoptera species (Undurraga & Stephen, 1980;Bennett et al, 2013;Rinehart et al, 2013).…”

Eristalinus aeneus (Scopoli) and Eristalis tenax (L.) (Diptera: Syrphidae, Eristalini) are important pollinator species that can be artificially reared and commercialised. To achieve better control over the pupal development time and adult emergence, cold storage techniques are suitable tools. Insects were reared under controlled conditions: 25 AE 1 °C, 50% r.h., and L12:D12 photoperiod. Pupae of both species were stored at 5 °C at the beginning (early treatments) or at the end (late treatments) of their development for various periods of time (5, 10, 15, 20, or 30 days). Development stopped completely at 5 °C in both treatments, but in general, pupae stored at the beginning of the pupal stage provided better results in terms of survival (adult emergence) and quality of the adults (general morphology). The cold tolerance of E. tenax was lower than that of E. aeneus, with their pupal developmental time successfully extended up to 18 and 23 days, respectively, without compromising survival and morphology. The number and types of morphological alterations due to cold storage were recorded.

“…Even so, the sublethal effects still needed to be closely monitored when make a comprehensive evaluation of a storage technique. Speci cally, the sublethal effects generally include delayed oviposition, lower fecundity and fertility and lower voracity 4 or parasitism 5 . Until now, these effects were mostly conducted on parasitoids and rarely quanti ed in predators 4 .…”

Indoor-reared natural enemy with high quality after long-term cold storage is crucial for sustainable pest management. However, besides survivals, the sublethal effects were not widely been reported. In this study, Harmonia axyridis (Pallas), an important biological control agent in Asia, was reared with β-carotene-amended artificial diet (Ha-Car) before storing at 6°C. After 30, 60, 90 and 120 days of storage, a series of biological parameters were measured to evaluate the fitness of H. axyridis. We found that: (1) Survivals significantly decreased with prolonged storage, and more Ha-Car individuals survived at day 120 compared to Ha-CK (control); (2) The contents of glycogen and trehalose dramatically decreased following storage, and the weight losses gradually increased; (3) The average egg production and hatch rates within 15 days were not significantly different among treatments Ha-Car and Ha-CK following long-term storage (90 and 120 days), while the daily hatch rates gradually decreased from relatively high to zero at day 14 and 15; (4) The number of micropyles deposited on eggs also gradually decreased along with oviposition period. After re-mating with a new non-stored partner, the egg viability gradually increased again, while low egg viability was still detected in F1 generation. Moreover, reduced number of micropyles were detected on their eggs. In summary, Ha-Car can be cold stored for about 120 days with relatively high survivals and fecundity, but long-term storage produced remarkable intra- and trans-generational negative effects on fertility. Even though, the cold-stored H. axyridis had great potential being used in biological control program with inevitable promiscuity with field individuals.
