Here, we provide a timely review on the current distribution, damage, management, and research in China. A standard survey form was designed and 30 answered surveys from 25 provinces have been received. The data showed that the damage has been witnessed in most of the regions despite that the severities vary among the regions. The management is chemical-control biased, and more efforts are needed to increase the adoption of non-chemical alternatives in the Integrated Pest Management packages. An Integrated Pest Management (IPM) package called “CAMEFA” was developed and demonstrated in Yunnan and Xinjiang, the two earliest regions for the invasion. Yet, the adoption by local growers is still limited. Besides T. absoluta, we suggest a multi-pest approach by combing IPM tactics coping with other major insect pests sharing the crop. Lastly, international projects are deemed to serve as a key lever for promoting IPM of T. absoluta and other invasive insect pests.","PeriodicalId":11728,"journal":{"name":"Entomologia Generalis","volume":"27 1","pages":""},"PeriodicalIF":6.9,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141060135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The biopesticide spinosad is widely used for controlling T. absoluta. This study aimed to investigate the spinosad-induced intergenerational sublethal effects on T. absoluta. Results showed that spinosad exhibited high toxicity against 3rd instar T. absoluta with the LC50 of 0.04 mg L-1 after 72 h exposure. The LC10 and LC30 of spinosad significantly decreased the durations of various developmental stages and some reproductive parameters of parental (F0) T. absoluta compared to control. The developmental durations, survival rate, reproduction and life table parameters (intrinsic rate of increase, r; finite rate of increase, λ; net reproductive rate, R 0; and oviposition days, Od ) were significantly decreased in the progeny generations (F1 and F2) following F0 exposure to the LC10 and LC30 of spinosad as compared to the control group. Additionally, the mRNA expression levels of development and reproduction related genes such as Vg, VgR, and JHBP were down-regulated in parental and progeny generations at both spinosad treatments as compared to control treatment. The resistance related cytochrome P450 genes CYP321C40 and CYP6AW1, followed by CYP4M116, CYP9A307v2, CYP15C1, CYP339A1, and CYP6AB327 were up-regulated at spinosad-treated groups in the parental and progeny generations of T. absoluta as compared to control.

In the last fifteen years, it has invaded and rapidly expanded across most European and African countries. This poses increasing threats to key tomato-growing regions worldwide. Despite the global significance of crop damages caused by T. absoluta, existing models have primarily focused on the developmental growth at the individual level, with limited consideration for population and community-level interactions, especially the plant-pest relationship. Here we introduce and discuss an ecological, process-based, mathematical model that accounts for the interdependent dynamics between a population of the herbivorous insect and the tomato plants it feeds on. The model explicitly integrates the impacts of water and nutrients availability, as well as temperature, on the growth of both insect and plant populations. After calibrating the model using empirical data, we find that its simulations can replicate different observed patterns. Leveraging the mechanistic nature of our approach, we analyze the combined effects of various temperature, fertilization/irrigation (fertigation) and biocontrol scenarios on (i) crop growth and (ii) the overall health of the production system. This enables us to identify knowledge gaps and to discuss the effectiveness and trade-offs associated with different management policies.","PeriodicalId":11728,"journal":{"name":"Entomologia Generalis","volume":"28 1","pages":""},"PeriodicalIF":6.9,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140833967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because the male individuals have six stages while the female individuals have only five stages, a new method was developed for a correct description of life stages and life table analysis. In general, the developmental durations of individually-reared insects were significantly longer than those of group-reared insects. Although the mean fecundity (F = 167.84 eggs/female) and the net reproductive rate (R0 = 62.10 offspring) of the individually-reared cohort were significantly higher than those of group-reared cohort (F = 66.5 eggs/female and R0 = 18.62 offspring), there were no significant differences in the population growth rates, i.e., intrinsic rate of increase r and finite rate of increase λ. Because the age variable x is an exponent in the Euler-Lotka equation, the first reproductive age and total preoviposition period are important factors in the determining the value of population growth rates. The life table data were used to simulate the population growth and timing of the control. Our results demonstrated that for group-lived insects like papaya mealybug, life table data collected using group-reared cohort is a better option for simulating pest population growth and management than data from individually-reared cohort.","PeriodicalId":11728,"journal":{"name":"Entomologia Generalis","volume":"17 1","pages":""},"PeriodicalIF":6.9,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140886960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pest has also been found to be damaging potato, but little is known about the performance on potato. To evaluate the adaptability of T. absoluta on potato and screen the resistant cultivars, the performance of T. absoluta was determined on four widely-grown potato cultivars (Qingshu No. 9 [QN9], Lishu No. 6 [LN6], Hezuo No. 88 [HN88] and Mila [MI]) in China using the age-stage two-sex life table, compared with tomato cultivar (Shouhe) as a control. The activity of several enzymes in the larvae were also determined. We found that T. absoluta could complete life cycles on the leaves and tubers of four potato cultivars, but was less harmful to tubers. The intrinsic rate of increase was the least on leaves of HN88, higher on leaves of QN9, LN6 and MI, and highest on tomato leaves. The lowest and highest fecundity of T. absoluta was recorded on the cultivar HN88 tubers and MI leaves, respectively. Moreover, the lowest pupal weight of T. absoluta was observed on the cultivar of QN9 leaves. The enzyme activities of the larvae feeding on difference cultivars did not show a clear pattern. In conclusion, T. absoluta showed high damage potential to potato, with the highest and lowest fitness to the potato cultivar MI and HN88, respectively.

However, research on the repellent plants of T. absoluta is missing. In this study, we assessed the potential of nine commonly reported repellent plants. Rosmarinus officinalis was found to exhibit a significant repellent effect against T. absoluta. We quantified the volatile organic compounds (VOCs) in R. officinalis, and further determined the repellent effects of the specific VOCs. The plant R. officinalis and the VOC eucalyptol delayed the developmental period of T. absoluta and decreased the egg-hatching rate. By running cage and greenhouse experiments, we confirmed that R. officinalis and eucalyptol reduced the damage caused by T. absoluta via antixenosis (i.e. reduced number of eggs laid).

Historically, insecticides have been used extensively to control T. absoluta, but resistant populations have been frequently detected. Biological control represents a sustainable and effective method with which to prevent and control T. absoluta. Egg parasitoids from the family of Trichogrammatidae (Hymenoptera) have been identified as potential biological option for controlling of T. absoluta. In the present study, we aimed to identify local dominant Trichogramma species that exhibited the best biological control ability against T. absoluta in China. To accomplish this, we compared the selectivity and number of offspring of three Trichogramma species to T. absoluta by performing host preference experiments in the laboratory. We also evaluated the fitness of Trichogramma against T. absoluta by assessing the parasitic ability and behavior of their offspring on different hosts. Compared with Trichogramma chilonis and Trichogramma dendrolimi, Trichogramma ostriniae exhibited a significantly greater preference to T. absoluta eggs and produced a higher number of offspring. The emergence rate and proportion of female T. ostriniae parasitizing the eggs of T. absoluta was higher than that of the other two Trichogramma species, the rate of T. ostriniae offspring deformity was only 3.00%. In addition, T. ostriniae has shortest immature stage and the longest adult stage among the three species.

Our results showed that both strains can parasitize, feed and directly kill 1st to 3rd instar T. absoluta larvae. In contrast, in 4th instar larvae, both strains only kill larvae by host-stinging. When the 1st instar host was constantly provided, the TH strain showed significantly greater biocontrol potential than the AR strain.
