“…Cryopreservation in liquid nitrogen is an emerging method for preserving Trichogramma species for mass rearing (Paixão et al, 2018). The storage of Mythimna sequax eggs in liquid nitrogen is an effective method for mass-producing Trichogramma species, with high performance and fecundity reported in storage periods of up to 106 days (Krechemer & Foerster, 2016). T. pretiosum females can parasitize 10 eggs without increasing density, and their performance did not differ from that of non-stored eggs for three generations, indicating the high efficiency of this storage strategy (Paixão et al, 2018).…”

“…T. pretiosum females can parasitize 10 eggs without increasing density, and their performance did not differ from that of non-stored eggs for three generations, indicating the high efficiency of this storage strategy (Paixão et al, 2018). Further investigation is required to prolong the storage duration of Trichogramma species while preserving their reproductive capacity, which is vital before their deployment in the field (Krechemer & Foerster, 2016).…”

The fall armyworm (FAW), Spodoptera frugiperda, causes harm to over 360 plants by eating both the vegetative and reproductive components. While synthetic insecticides have been widely used to manage this pest, they pose a significant ecological risk to beneficial insects. The Trichogramma genus, comprising over 240 parasitoid species, presents a promising alternative to insecticides. They utilize the chemical signals emitted by host eggs to locate and lay their eggs inside, ultimately leading to the host’s death. This review aims to provide comprehensive insights into the potential of Trichogramma species as biocontrol agents of S. frugiperda, highlighting both their potential and challenges in augmentative biocontrol alongside chemical control. penetrative ability, cost of mass-rearing, frequency, and release-timing of the parasitoid, influence its application and effectiveness in managing S. frugiperda in agroecosystems. The typical problem of Trichogramma’s low penetrative ability of scaled S. frugiperda egg mass can be resolved by integrating other parasitoids that can easily penetrate the egg barriers. Also, certain pesticides registered for controlling S. frugiperda require re-evaluation to learn about their effects on Trichogramma species, inform conservation strategies, and promote sustainable pest management.

“…Generally cold storage is followed to meet the demand of farmers as and when required and to reduce wastage in biological material, Trichogramma mass rearing and host eggs storage (Spinola et al, 2014;Colinet and Boivin, 2011;Huang et al, 2017;Peverieri et al, 2015). However, cryopreservation of parasitoid focus in most the studies while storage of host eggs in cold temperature is rarely investigated (Krechemer and Foerster, 2016;Tezze and Botto, 2004;Colinet and Boivin, 2011;Özder, 2004 Eco.

The eggs of Corcyra cephalonica were stored at four different cold storage temperature viz. 4±1°C, 8±1°C, 10±1°C and 12±1°C for storage duration 15, 25, 35 and 45 days in refrigerator and BOD incubators. The parasitization efficiency on stored Corcyra egg by mother culture of Trichogramma chilonis were studied under standard laboratory condition. The parasitization is found to be maximum (92.30%) when Corcyra egg stored at 4±1°C upto 15 days. The per cent parasitization gradually decreased with the increase in duration. After 25, 35 and 45 days of storage the parasitization were reduced to 75.20%, 73.50% and 40.50% respectively at 4±1°C followed by 8±1°C with 82.60%, 75.30% and 25.60% respectively. The parasitization 86.00% was found to be highest at 10±1°C for 15 days of storage followed by 8±1°C (85.70%). The parasitization rate gradually decreasing with increase in storage duration and reached to 52.55% at 10±1°C upto 45 days of storage. The 4±1°C is best temperature for storage of Corcyra cephalonica egg followed by 10±1 °C upto 45 days of storage. The higher temperature 12±1°C were found unsuitable for storage of Corcyra cephalonica egg.

“…have mentioned cold storage of host eggs and its possible effect on Anastatus fitness, but the most effective methods for host egg storage have not been reported [7,9,11,12]. Parasitoids reared on refrigerated eggs may have reduced fitness, because long-term cold storage of host eggs can decrease their quality [10,[12][13][14][15]. A decrease in the female ratio of Anastatus spp.…”

Chinese silkworm (Antheraea pernyi) eggs are used as factitious hosts of Anastatus fulloi, and refrigeration of these eggs is essential for large-scale rearing of A. fulloi. We studied the effects of cold storage of A. pernyi eggs on egg quality and the fitness of A. fulloi reared on the eggs. Four cold storage treatments and two cold storage periods were assessed. The 0–3 °C refrigerator treatment was unsuitable for long-term (>70 days) storage. Cold storage at −5 °C and −18 °C increased the loss rate of A. pernyi eggs, but there was no significant difference between the control and 0–3 °C water bath treatment. The parasitism rate of A. fulloi was reduced when A. pernyi eggs were refrigerated for 6 or 12 months. There were no obvious differences in eclosion rate and percentage of females between control and eggs subjected to 6-month storage in 0–3 °C, −5 °C, and −18 °C water bath treatments. However, the eclosion rate and percentage of females decreased sharply when the storage period was 12 months. The overall eclosion rate of A. fulloi was reduced at the prolonged refrigeration time. Cold storage reduced host egg quality and their fitness suitability for A. fulloi. To minimize losses in the large-scale rearing of A. fulloi, A. pernyi eggs should be refrigerated in a 0–3 °C or −5 °C water bath treatment, and the storage period should not exceed 6 months.
