“…As the last development stage of nymphs were used for irradiation experiments here, potentially we are observing that newly emerged adults might be more sensitive to radiation than fully mature nymphs. Welsh et al (2017) reported that the longevity of female insects was negatively affected by its irradiated male partner at doses above 32Gy [20]. We did not observe the effect in our study (p=0.6849, Table 1).…”

“…Normally, the insects should be irradiated at the early stage when the sperm cells are not well developed to get high effectiveness [17]. In the case of BMSB which is an incomplete metamorphic insect species, our results suggest that the SIT can be applied for BMSB management when irradiating nymphal stage insects at doses from 16-64Gy, complementary to previous research conducted by Welsh et al (2017) and Suckling et al (2019) [20,21].…”

“…However, its background has only been well developed and applied for controlling a small range of pest species of primarily Diptera and Lepidoptera [18,30]. Few studies have been done for investigation of the irradiation biology of Hemiptera including the brown marmorated stink bug [19][20][21]. More research is still required in order to gain more insight into the irradiation biology of BMSB and Hemiptera more widely, before applying the SIT against BMSB in the field.…”

“…The sterilization of egg induced by irradiation is thought to be due to the breaking of the chromosome fragmentation of gonial cells, leading to genetically unbalanced gametes and subsequently inhibits the mitosis process, resulting in the death of fertilized eggs or embryos [26,31,32]. Welsh et al (2017) reported that the mortality of F1 egg of BMSB increased in response to irradiation doses absorbed by parental males, and eggs were completely sterile at doses above 32Gy [20]. In our experiment, the dose of 32Gy was not investigated but we observed a similar reduction in the hatching rate of eggs as the dose or radiation increased (p<0.001, Table 2).…”

The irradiation biology of the brown marmorated stink bug (BMSB, Halyomorpha halys Stål) treated at the nymphal stage was investigated to determine its application for sterile insect technique (SIT). Fifth instar males of BMSB were exposed to gamma-radiation 60 Co at different doses of 12, 16, 20, 24 and 64 Gy. Irradiated males were mated with non-irradiated virgin females to assess the longevity of both sexes, female fecundity and fertility of their offspring until the egg stage of the F2 generation. The mortality of each of the developmental stages of the F1 and eggs of the F2 generation was observed to determine whether negative effects from exposure to radiation was inherited. The data indicated that irradiation significantly reduced the lifespan of male insects at doses above 20Gy. Irradiated males did not affect the longevity and fecundity of their female partners, nor either sex of their resulting progeny, but it did reduce the hatch rate of the eggs at all doses tested. The sterility rates of F1 eggs were 55.6%, 73.3%, 74.1% and 74.1% at doses of 12Gy, 16Gy, 20Gy and 24Gy respectively. Eggs were completely sterile (100%) at a dose of 64Gy with no egg hatch recorded. A low hatch rate of F2 eggs illustrated that negative effects from radiation was inherited by the subsequent generation. The results support the potential for the use of SIT for BMSB management by irradiating the fifth instar male nymphs at 16-64Gy.

“…Host range testing was conducted on several non-target pentatomid bugs [17]. New Zealand has an official government goal of harnessing 4.7 million pairs of eyes for biosecurity [18], and has a long and successful track record of unwanted arthropod eradications [19], as well as a desire to avoid non-target impacts from new parasitoids where possible [20], leading to our search for possible alternative eradication technologies, such as the sterile insect technique [21].…”

Improvements to current brown marmorated stink bug (BMSB), Halyomorpha halys, surveillance and killing systems are needed to improve detection sensitivity and to reduce pesticide use. Detection of BMSB in New Zealand with traps is reliant on sticky panels with aggregation pheromone, which are low cost but inefficient compared with beating foliage. Trapping for BMSB adults and nymphs was conducted daily with lethal traps consisting of an aggregation pheromone-baited-coat hanger covered with dark-colored long-lasting insecticide-treated mesh, we termed “The Nazgȗl”, based on its sinister appearance. A deep tray lined with white plastic was attached centrally at the base for collecting the dead BMSB. The lethal traps killed and caught up to 3.5-fold more nymphs and adult BMSB than identically-baited sticky panels in the 3 weeks of deployment, and provided a snapshot of phenology by instar. We expect that lure-and-kill stations could contribute to the suppression of a delimited population and could be included as part of a semiochemical-based eradication program. Attracting and killing females and nymphs, thus removing future offspring, could contribute to population suppression during an eradication.

Behaviour and fitness impacts of irradiation-induced sterility in an egg parasitoid and potential implications for their use for insect eradication

et al. 2023

As the increasing globalisation of trade generates an escalating spread of arthropod pests, eradication has gained traction as a viable approach to avoiding the growing long-term management costs. The Sterile Insect Technique (SIT) involves releasing sexually sterile insects into the wild population and has been employed for environmentally friendly eradication. Alternatively, classical biological control (CBC) comprises the importation and release of natural enemies. Although generally used for long-term management, evidence suggests a synergistic impact could be exerted on pest populations when combined with SIT, potentially improving eradication outcomes. It is possible that sterile parasitoids, which would not bear the risk of irreversible non-target impacts associated with conventional CBC releases, could be accepted by regulatory agencies as a safe option to be used as a synergistic component of eradication. We investigated the post-irradiation behaviour and fitness of the egg parasitoid Trissolcus basalis to determine whether irradiation-induced sterility may reduce its efficacy. In comparing sterile and non-sterile parasitoids, there were no observable differences in searching behaviour, no significant differences in the number of egg masses found and parasitised, nor longevity. It is possible that sterile parasitoid release could contribute to an eradication programme without detrimental effects.
