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. Considering bottom-up effects as a key driver in integrated pest management (IPM), the cultivars HN88 and QN9 could be preferably used in the IPM.","PeriodicalId":11728,"journal":{"name":"Entomologia Generalis","volume":null,"pages":null},"PeriodicalIF":6.9,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140614304","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}

Adverse effects associated with the overuse of chemical insecticides have prompted researchers to seek ecologically-based management options, such as using secondary plants. 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). Our results showed the important function of R. officinalis and its VOCs in controlling T. absoluta, guiding the use of repellent plants as a key component of Integrated Pest Management packages.","PeriodicalId":11728,"journal":{"name":"Entomologia Generalis","volume":null,"pages":null},"PeriodicalIF":6.9,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140614307","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}

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. In conclusion T. ostriniae can be a promising native biological control agent against T. absoluta in China.","PeriodicalId":11728,"journal":{"name":"Entomologia Generalis","volume":null,"pages":null},"PeriodicalIF":6.9,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140614352","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}

Applying integrated pest management (IPM) approaches using combinations of biocontrol agents with agronomic practices such as the modulation of fertilisation offers opportunities toward more efficient pest control, all the more so since the underlying bottom-up and top-down regulations are interdependent. We investigated the relative influence of the bottom-up effects of reduced fertilisation (by 47%) and the use of the mirid predators Dyciphus errans or Macrolophus pygmaeus in combination with Nesidiocoris tenuis on the control of B. tabaci and T. absoluta. Densities of B. tabaci and T. absoluta population decreased more rapidly when fertilisation was reduced. The presence of D. errans caused reduction in N. tenuis densities and in the number of necrotic rings caused by N. tenuis. The negative effects of bottom-up forces triggered by reduced fertilisation on B. tabaci, T. absoluta and N. tenuis populations and damage were greater in the presence of D. errans. Our study shows that interactions between predators and fertilisation management are important in agro-ecosystems and should be considered in the development of sustainable IPM strategies.","PeriodicalId":11728,"journal":{"name":"Entomologia Generalis","volume":null,"pages":null},"PeriodicalIF":6.9,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140585085","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}

Neochrysocharis formosa, a host-feeding parasitoid wasp, has thelytokous (TH) and arrhenotokous (AR) strains with sympatric distributions in many regions of China. To clarify the biocontrol potential of the two strains, we evaluated the host-killing behaviors on different instar larvae of T. absoluta and the life history traits of the two strains reared on T. absoluta. 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. The former had higher fecundity (2.10-fold), killed more larval hosts (1.57-fold), survived longer (1.37-fold), and had more offspring (2.07-fold) that successfully emerged. In summary, the TH strain of N. formosa is a better candidate for biological control than the AR strain of T. absoluta.
