Food shortages severely reduce the prospects of insect survival in natural settings, including in the case of herbivorous insects. However, the early starvation experience of some insects has positive effects throughout their entire lifespan. It is important to discuss the effects of refeeding and host plants on the capacity of herbivorous insects to adapt to starvation and low temperatures, considering that starvation resistance is expected to show some degree of adaptive phenotypic plasticity. We tested the relationship between host plant, starvation, and the supercooling capacity of the invasive pest Corythucha marmorata. In particular, we highlighted how early starvation affects the refeeding and recovery phases. Among the various range of hosts, the chrysanthemum lace bug has the fastest growth rate on Helianthus annuus, and the strongest supercooling capacity on Symphyotrichum novi-belgii. Especially, starvation for 2 days increases the rates of survival, development, and number of eggs upon refeeding, in comparison to no starvation. A 3-day starvation period in the nymphal stage significantly increased the supercooling capacity of 5th instar nymphs and adults, as observed in our study.

“…When the female died before the end of the seventh day, a notable decrease in parasitization was observed, with many failing to parasitize a single larva the day prior to their death. The same has been seen in other Ichneumonidae, with productivity gradually declining around the halfway point of their lives until they stopped reproducing shortly before their deaths [55,56]. The transition from pupa to emerged adult was a second critical period in the rearing; the first being the initial parasitization on the first day.…”

The Parasitoid Hyposoter didymator Can Transmit a Broad Host Range Baculovirus in a Two Host System

Hyposoter didymator (Thunberg) (Hymenoptera: Ichneumonidae) and baculovirus (BV) might be used jointly to provide effective control of the Spodoptera genus. The literature has mostly covered the safe compatibility between natural enemies and BV-based insecticides, but research on the potential dispersal of BV by natural enemies is lacking. Thus, the goal of this manuscript was to ascertain if H. didymator was able to disperse the broad host range of Autographa californica nucleopolyhedrovirus (AcMNPV) to Spodoptera littoralis and Spodoptera exigua in choice and non-choice conditions and whether the preference of the parasitoid by one of these noctuids could mediate this dispersion. It was previously needed to improve the rearing of the parasitoid in the laboratory, concerning the optimal host age and length of parasitization, parasitoid competition, and influence of parasitization on the longevity of females. The best rearing conditions for S. littoralis are collective parasitization of mature L3 larvae for 24 h, after at least one day of copulation. Hyposoter didymator transmits AcMNPV to both lepidopterans, but its efficiency is mediated by host preference and the pathogenicity of the BV in each host. In this particular case, H. didymator as well as AcMNPV showed a clear preference towards S. exigua.

“…The post-oviposition period refers to the time when a parasitoid ceased to parasitize hosts until the death of the parasitoid. Two fecundity parameters were calculated, realized fecundity as the number of parasitized larvae that developed in a cocoon (whether it developed into an adult parasitoid or not) over the life-span of the parasitoid, and fertility as the number of adult parasitoids that emerged from cocoons (Murillo et al ., 2012).…”

The temperature-dependent development of Apanteles hemara (Nixon), a larval endoparasitoid of the devastating amaranth pest Spoladea recurvalis (F.) was studied in the laboratory at six constant temperatures (10, 15, 20, 25, 30 and 35 °C), a photoperiod of 12L:12D and a relative humidity of 60–70%. Developmental time decreased significantly with increasing temperature within the range of 15–30 °C. The parasitoid's pupal mortality, successful parasitism rate, adult emergence rate and longevity, sex ratio and fecundity were affected by temperature. The population of A. hemara failed to develop at 10 and 35 °C. The development threshold (Tmin) and the thermal constant (K) were calculated by the linear model while the lethal temperature (Tmax) was determined by the Lactin-1 model. The estimated values of Tmin, Tmax and K by the two models were 10.3 °C, 35.0 °C and 185.18 DD respectively for the total immature development. The estimated value of the optimum temperature using the Taylor model was 30.8 °C. This is the first study to report on the effect of temperature on the developmental parameters of A. hemara giving an insight into its biology. The implications of these findings for the use of A. hemara in biological control are discussed.
