However, interactions among mycorrhizal fungi, wheat plants, and aphids like the English grain aphid Sitobion avenae (Hemiptera: Aphididae) under water-deficit stress are still not well understood. Here, we examined the colonization of the fungus Claroideoglomus etunicatum (Glomerales: Claroideoglomeraceae) on wheat, and its effects on development and behavior of S. avenae under different water regimes. The symbiosis between C. etunicatum and wheat tended to increase the total developmental times of S. avenae nymphs under water deficit, but decreased adult lifespans. Irrespective of water conditions or wheat cultivars (Xinong-979 and Chang-6794), this symbiosis tended to cause higher adult weights and fecundities of S. avenae. These findings suggested that inoculation of this fungus could induce some life history trait trade-offs for S. avenae. Inoculation of C. etunicatum caused significant increases in contents of total amino acids in Xinong-979, and contents of some individual amino acids (e.g., glutamine) in both cultivars. This aphid preferred settling on symbiotic plants, with alate individuals attracted to well-watered Xinong-979 from 4 and Chang-6794 from 24 h postrelease. Increased phloem feeding and reduced pathway phase time for S. avenae were found in symbiotic plants. The fungus C. etunicatum also significantly enhanced wheat growth, especially under water deficit, and increased contents of nonessential and essential amino acids in Xinong-979. Our results highlight complex interactions among fungus symbiosis, wheat cultivars, and water conditions, emphasizing the potential to boost wheat crop resilience in the context of global climate change.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"203-218"},"PeriodicalIF":0.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142886578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the objectives of this study were (i) to determine ethanol release rates from these baits under constant and variable temperatures and (ii) to compare relative adult Xylosandrus spp. captures using these baits in ornamental nurseries. When 3-d difference (3-d difference) bait weights were recorded under constant 15.6, 21.1, 26.7, and 32.2 °C, an increase in release rates was recorded with an increase in temperature from 15.6 to 32.2 °C for LR bait. At 32.2 °C, no increase or reduction in the 3-d-difference weights was found for the HR and Trécé baits, respectively, compared to LR bait. The 3-d-difference weights were steady with all 3 baits when temperatures gradually increased and decreased in variable sequence for 30 d. In 2022, 2023, and 2024, although all 3 baits captured adult X. crassiusculus and X. germanus, LR bait captured significantly more numbers of X. crassiusculus than the other 2 baits in 2022 and 2023, and in 2024, X. crassiusculus captures were greater in traps with the Trécé bait than the other 2 baits.

In Taiwan, invasion of A. gracilipes has been associated with the declining of land crab populations in several hotspots. While liquid baiting program has been implemented in those areas, the operation is costly and labor-intensive since it typically requires the use and maintenance of bait stations. The goal of the current study was to evaluate the potential and effectiveness of hydrogel baits laced with borax as an alternative tool to control A. gracilipes. Laboratory studies demonstrated that hydrogel baits containing 3% borax achieved higher A. gracilipes mortality than those containing 2% and 1% borax. Specifically, hydrogel baits containing 3% borax resulted in >90% worker mortality within 21 d post-treatment (LT50 = 5.1 d), along with significant reduction in brood weight (>90%) and substantial queen death (>80% of colony fragments). Furthermore, field experiment indicated that A. gracilipes workers preferentially retrieved small-size hydrogel beads (3.1 mm OD; proportion removed = 1.00 ± 0.00) compared to the larger ones (6.2 mm OD; proportion removed = 0.03 ± 0.03), which will facilitate efficient transfer of toxicant within the colony and may minimize nontarget impact. In conclusion, alginate hydrogel baits with 3% borax appear to be a promising tool against A. gracilipes, although their field efficacy against large supercolonial populations remains to be investigated.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143384426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2017, damaging populations of P. perseae were discovered in commercial Hass avocado groves in San Diego and Riverside Counties. The unexpected and rapid spread of P. perseae raised the question of whether this range expansion was an extension of the original incursion or the result of a second invasion event. Using sequences of the mitochondrial COI gene, we found strong evidence that P. perseae populations in southern San Diego County are comprised almost entirely of the single haplotype (A) that was detected in 2004. In contrast, newly established (2017 onwards) populations of P. perseae infesting commercial orchards consisted exclusively of a second mitochondrial haplotype (G). This haplotype is found in Florida and the Caribbean and is conclusive evidence that California has been invaded a second time. Molecular analyses also confirmed that invasive P. perseae populations in Hawai'i are haplotype G, indicating that California and Hawai'i populations may have originated from the same source area (possibly Florida), or that California may have acted as an invasion bridgehead for the invasion of Hawai'i. Reproductive compatibility of the primary (haplotype A) and secondary (haplotype G) invasive populations in California was confirmed via a series of reciprocal laboratory crosses and results suggest that fertility of hybrid eggs is increased. The potential consequences of this second invasion into California by P. perseae are discussed.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143384458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the performance of mass-reared adult Ceratitis capitata Wiedemann (Diptera: Tephritidae) under constant (24 °C) and oscillating (mean 24 °C with 4 and 10 °C range) temperature regimes. Insect survivorship, flight ability, and female fecundity were assessed across the temperature regimes. Additionally, we compared adult C. capitata performance under environmental chamber and outdoor conditions to determine if temperature and humidity as simulated in the chambers resulted in similar performance outcomes for the insects as being outdoors. Male C. capitata under the 10 °C range treatment had higher survival probability at 55 d postemergence compared to the constant temperature regime, while females showed no significant differences in survivorship among temperature regimes. Flight ability and fecundity were not significantly affected by temperature regimes, though the 10 °C range group showed the highest fecundity. Comparisons between environmental chamber and outdoor conditions revealed minimal differences in performance metrics.

Similarly, the addition of supplemental nutrients resulted in a reduction in the mean generation time (T) and an enhancement of the net reproductive rate (R0), intrinsic rate of increase (r), and finite rate of increase (λ) compared to the control group.

Our findings indicate that both the green peach aphid Myzus persicae (Sulzer) (Hemiptera: Aphididae) and the English grain aphid Sitobion avenae (Fabricius) (Hemiptera: Aphididae) avoided settling on an artificial diet containing lactisole or on host plants treated with lactisole. In addition, these aphid species showed reduced weights when feeding on the artificial diet containing lactisole or on seedlings root drenched by lactisole. Furthermore, data from the electrical penetration graph revealed that S. avenae exhibited a greater number of phloem probes but significantly shorter mean and total phloem ingestion durations when feeding on wheat plants root-drenched by lactisole. It is worth noting, however, that root drenched by lactisole had a significant inhibitory effect on plant growth.

Effective earwig monitoring and trapping are critical for understanding their biological control potential in orchards. Traps made of rolled, corrugated cardboard have long been used for earwig monitoring; however, no standardized studies have investigated improvements to them. In a series of trials, we explore options to improve traps by testing different trap materials, sizes, positioning on the tree, and time in the field, in addition to the lures and baits. We found that cardboard traps had higher earwig catch than black or translucent plastic traps. There were diminishing returns in earwig capture for increased trap length, plateauing at ~30 cm. Traps placed on the main trunk captured more earwigs than traps on the base or near the end of branches. Lures and baits mostly did not increase trap efficacy, except fish sauce which inconsistently increased earwig captures. The use of plastic bottles to contain the cardboard traps greatly reduced trap catch. Finally, we found evidence that traps left in the field for longer periods of time can increase earwig capture, possibly due to the accumulation of earwig aggregation pheromone. Overall, the standard unbaited corrugated cardboard trap was the most effective and practical earwig monitoring trap.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143367112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In temperate tree fruit crops, the European earwig, Forficula auricularia (L.) has only recently become appreciated as an important predator of economic pests, particularly woolly aphids and pear psylla. Therefore, the non-target effects of orchard pesticides on earwigs are largely understudied. This is particularly true for herbicides, which earwigs are likely to be exposed to due to their foraging behavior moving between the canopy and the ground cover. We tested residues of formulated pesticides (8 insecticides and 7 herbicides) commonly used in tree fruit crops for lethal and sublethal (movement, predation rate) effects on adult female earwigs. Two herbicides, paraquat and glufosinate, and one insecticide, spinetoram, were acutely toxic to earwigs within 72 h. No tested pesticides altered earwigs' movement or resting behavior compared to the control. The insecticides spinosad and cyantraniliprole and the herbicides 2,4-D, glufosinate, halosulfuron, rimsulfuron, and oxyfluorfen reduced earwig predation on green peach aphids. Therefore, these pesticides may reduce earwig predation on pests in orchards. Our results suggest that some pesticides are of greater risk, and thus, should be carefully considered or better timed when used in tree fruit orchards where earwigs are considered for conservation or augmentative biological control.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143191566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
