“…The results provided here on the key reproductive traits of the species, their synovigenic strategy and long lifespan, together with the high parasitism levels previously reported (Manzano et al, 2021) are key for breeding and pest management programmes and support evidence for C. annulicornis as a promising biocontrol agent for the sharpshooter T. rubromarginata.…”

“…Each exposed leaf carrying host eggs was removed from the experimental arena after 24 h and kept inside Petri dishes with a plaster base moistened with distilled water and covered with plastic film to prevent parasitoids from escaping. The number of parasitized eggs was recorded by counting host eggs that had undergone a change of coloration from yellowish to dark brown (Manzano et al, 2021). To confirm parasitism, emergence of the adults was observed (only one adult emerged per host egg) and the remaining host eggs with no clear evidence of parasitism or parasitoid emergence were dissected in order to detect parasitoid larvae or pupae inside the eggs.…”

“…Cosmocomoidea annulicornis (Ogloblin) (Hymenoptera: Mymaridae) is a solitary egg parasitoid of Proconiini sharpshooters including Tapajosa rubromarginata (Signoret) (Hemiptera: Cicadellidae) (Triapitsyn et al, 2010;Manzano et al, 2021), a polyphagous sharpshooter present in citrus agroecosystems and vector of the bacterium Xylella fastidiosa Wells et al (Xanthomonadaceae), causal agent of citrus variegated chlorosis (Dellapé et al, 2016). The mymarids are among the most important natural enemies of insect pests (Peña et al, 2009), and members of this family are biological control agents of sharpshooters (Grandgirard et al, 2007(Grandgirard et al, , 2008Banks et al, 2019).…”

“…Previous field reports showed that C. annulicornis is a widely distributed (Triapitsyn et al, 2010) and abundant species, and some biological features, including parasitism, functional response and developmental rate have been evaluated in the laboratory (Manzano et al, 2021). However, aspects of the reproductive biology of the species are still unknown.…”

The reproductive traits of the mymarid wasp Cosmocomoidea annulicornis (Ogloblin) (Hymenoptera: Mymaridae) attacking eggs of the sharpshooter Tapajosa rubromarginata (Signoret) (Hemiptera: Cicadellidae) were evaluated under laboratory conditions. Bioassays were carried out to estimate the realized fecundity and egg load of females. The ovigeny index was calculated and different biological traits, such as body size, oöcyte length, gaster length and wing length, were analysed to assess significant associations between these traits and the species fitness. In addition, the effect of host availability and feeding on longevity and potential fecundity throughout life and the effect of female age on egg maturation dynamics were assessed. The results showed that C. annulicornis is a strongly synovigenic species. A positive correlation was found between fecundity and longevity of the females and between body size and oöcyte length. Contrary to expected, body size was not related to fecundity and longevity. Females lived significantly longer in the presence of hosts and honey than when they were host-deprived and honey-fed or both host and honey deprived. Host availability had a significant effect on the amount of eggs laid by C. annulicornis females. Female age was negatively associated with oöcyte length. Furthermore, females were able to mature additional eggs as they aged, nevertheless, when host-deprived, senescent females presented significantly less mature eggs than younger ones, suggesting a possible egg oosorption. These results might contribute to a better understanding of the reproductive potential of this species as a biocontrol agent.

“…The lowest egg load observed is when the females are 1 and 12 hours old and the highest when females are 4, 5, and 8 hours old. [69]. On the other hand, in the egg parasitoid Anagrus virlai Triapitsyn (Mymaridae), the number of parasitized eggs decreases as females age, and wasps experience a double egg maturation process [30].…”

Functional response describes the number of hosts attacked by a parasitoid in relation to host densities and plays an important role by connecting behavioral-level processes with community-level processes. Most functional response studies were carried out using simple experimental designs where the insects were confined to a plain and small arena with different host densities during a fixed period of time. With these designs, other factors that might affect the functional response of parasitoids were not analyzed, such as fecundity, age, and experience. We proposed a series of latent-variables Markovian models that comprised an integrated approach of functional response and egg production models to estimate the realized lifetime reproductive success of adult parasitoids. As a case study, we used the parasitoids Anagyrus cachamai and A. lapachosus (Hymenoptera: Encyrtidae), two candidate agents for neoclassical biocontrol of the Puerto Rican cactus pest mealybug, Hypogeococcus sp. (Hemiptera: Pseudococcidae). Anagyrus cachamai and A. lapachosus presented a type III functional response. However, the two parasitoids behaved differently: for A. cachamai, the number of parasitized hosts decreased with female age and depended on the number of mature eggs that were available for oviposition, whereas A. lapachosus host parasitism increased with female age and was modulated by its daily egg load and previous experience. The tested species were assessed according to their physiology and prior experience. We estimated the number of mature eggs after emergence, egg production on the first day, egg production rate, proportion of eggs resorbed, egg resorption threshold, and egg storage capacity. The methodology presented may have large applicability in pest control, invasive species management, and conservation biology, as it has the potential to increase our understanding of the reproductive biology of a wide variety of species, ultimately leading to improved management strategies.
