The species has expanded its range to the Pacific Rim since 2000s and Japan has faced its multiple introductions since 2017. While colony-level control methods are urgently needed, testing living colonies of the unestablished species is challenging especially due to various restrictions under the COVID-19 pandemic. Here, we proposed alternative long-term toxicity assays using artificial colonies of Tetramorium tsushimae Emery (Hymenoptera: Formicidae), a Japanese native species belonging to the same subfamily (Myrmicinae) as S. invicta. We conducted an acute toxicity test to determine if T. tsushimae is a suitable substitute for S. invicta using fipronil and found the LD50 value in T. tsushimae was close to that in S. invicta. Then, we conducted the long-term toxicity test with fipronil and two insect growth regulators (pyriproxyfen and etoxazole) using artificial colonies of T. tsushimae. All workers and larvae in the fipronil-treated colonies died within 3 days of treatment initiation. Emergence of new workers was observed after 18 days in the etoxazole-treated and control colonies, but not in the pyriproxyfen-treated colonies. We concluded that fipronil was the most promising insecticide for post-establishment control, and pyriproxyfen was effective as a toxic-bait agent for colony-level control.</div>","PeriodicalId":8551,"journal":{"name":"Applied Entomology and Zoology","volume":"58 1","pages":"25 - 33"},"PeriodicalIF":1.3,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13355-022-00800-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10517069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To understand the mechanism underlying their coexistence, we investigated their habitat-use pattern, seasonal occurrence, and the frequency at which they were collected together in Sugadaira Montane (Nagano Prefecture), where grasslands, young forests, and mature forests are present. Slight differences in habitat-use pattern and seasonal occurrence were found between D. biauraria and D. triauraria. However, both species were sometimes collected together. Especially, D. triauraria females were collected together with heterospecific males, suggesting that D. triauraria females may be at risk of reproductive interference and hybridization.

The ability of released males to compete successfully against wild males is key to the success of the SIT. Artificial selection acting under mass-rearing conditions may alter male behavior in ways that decrease acceptance by wild females. A pupal-color sexing strain of melon fly (termed T1) was developed in Hawaii, and males of this strain appear equal to wild males in mating competition. In the present study, trials conducted in both laboratory and field cages showed that T1 and wild females mate indiscriminately among T1 and wild males. Trials conducted in field cages also assessed the impact of two elements—overflooding ratio (i.e., ratio of mass-reared to wild males) and use of male-only vs. bisexual releases—on the mating success of T1 males.

We compared the proportions of the ground surface wetted by spray droplets among four ground cover conditions. Also, we set up four treatments (with and without ground cover mowing and insecticide spraying) and compared the numbers of spiders trapped by pitfall traps. As a result, with unmown ground cover, the proportion of ground surface wetted by the spray droplets was small. Also, the number of spiders in the traps under unmown ground cover was not decreased by insecticide spraying, whereas spraying significantly decreased the number under mown ground cover.

In this study, we evaluated the bean bug Riptortus pedestris (F.) (Hemiptera: Alydidae), which enters adult (reproductive) diapause in response to short days. A gene encoding the insulin-like peptide ILP1, which is expressed in the pars intercerebralis in the brain, was upregulated and involved in fecundity under long days. Ilp1 appeared to function independently of the photoperiodic response controlled by juvenile hormone signaling. Cyp15, which encodes an epoxidase crucial for juvenile hormone biosynthesis, was upregulated and involved in ovarian development under long days. RNA interference targeted against the circadian clock gene per canceled the Ilp1 and Cyp15 suppression and allowed females to be reproductive even under diapause-inducing short days.
