“…The two Bactrocera species are similar in many biological attributes such as mating duration, oviposition preference, and offspring performance as well as sharing a common origin. However, the geographical distribution of B. dorsalis is now much wider than that of B. correcta both in China and elsewhere in the invasive range, which B. dorsalis has invaded including Hawaii, Kenya, and Tahiti and gradually displaced pre-established Ceratitis species in recent years (Figure 1; Hu, Chen, & Li, 2014;Liu et al, 2014;Liu, Jin, & Ye, 2013;Lux, Copeland, White, Manrakhan, & Billah, 2003;Reitz & Trumble, 2002). Thus far, there are no records of B. dorsalis being displaced by other tephritid fly species (Liu et al, 2017).…”

Many insects have the capacity to increase their resistance to high temperatures by undergoing heat hardening at nonlethal temperatures. Although this response is well established, its molecular underpinnings have only been investigated in a few species where it seems to relate at least partly to the expression of heat shock protein (Hsp) genes. Here, we studied the mechanism of hardening and associated transcription responses in larvae of two invasive fruit fly species in China, Bactrocera dorsalis and Bactrocera correcta. Both species showed hardening which increased resistance to 45°C, although the more widespread B. dorsalis hardened better at higher temperatures compared to B. correcta which hardened better at lower temperatures. Transcriptional analyses highlighted expression changes in a number of genes representing different biochemical pathways, but these changes and pathways were inconsistent between the two species. Overall B. dorsalis showed expression changes in more genes than B. correcta. Hsp genes tended to be upregulated at a hardening temperature of 38°C in both species, while at 35°C many Hsp genes tended to be upregulated in B. correcta but not B. dorsalis. One candidate gene (the small heat shock protein gene, Hsp23) with a particularly high level of upregulation was investigated functionally using RNA interference (RNAi). We found that RNAi may be more efficient in B. dorsalis, in which suppression of the expression of this gene removed the hardening response, whereas in B. correcta RNAi did not decrease the hardening response. The different patterns of gene expression in these two species at the two hardening temperatures highlight the diverse mechanisms underlying hardening even in closely related species. These results may provide target genes for future control efforts against such pest species.

“…The use of chemicals for pest control is worrisome not because of higher monetary investment but adverse environmental impact associated with their use. Amongst the 33.3-66.7% damage caused by fruit y infestation, B. dorsalis (Tephritidae) is a major pest of guava causing documented losses of up to 100%, worldwide (Dejen and Hassen, 2018;Liu et al, 2014;Sarwar et al, 2014). Hence, this fruit y species has been included in quarantine list of pest species according to the International Standards for Phytosanitary Measures (ISPM Measures 2018).…”

Bactrocera dorsalis (DIPTERA: TEPHRITIDAE), the primary pest of guava (Psidium guajava), damages numerous horticulture fruits in tropical and subtropical regions. Use of insecticides adversely affects agro-ecosystem and has environmental consequences.The repellent activity of Salix alba (Willow) bark extract and a Guava oil-based formulation was investigated to protect guava fruit from infestation by the Fruit Fly, B. dorsalis. In laboratory and semi-eld experiments, the e cacy of these natural repellents was assessed. B. dorsalis signi cantly deterred guava fruit treated with S. alba formulation as compared to the extract alone, which exhibited signi cant anti-feeding activity, and caused a decline in fecundity rate by 60% and larval mortality rate by 90%. When females were allowed to oviposit on guava fruits in laboratory and eld after mating, these ies preferred fruits for oviposition that were not sprayed with S. alba-guava oil formulation. GC-MS analysis showed esters and terpenes as the main components for exhibiting repellent property in S. alba-based formulation. Hence, guava oil formulation of S. alba showed a complete protection of guava fruits against B. dorsalis in the laboratory and semi-eld conditions to control infestation by B. dorsalis. Further research and eld trials are warranted to optimize the application methods and assess the long-term effects on crop yield and overall fruit quality.
