“…Dried fruit beetle, Carpophilus hemipterus (Linnaeus, 1758) (Coleoptera: Nitidulidae), is a serious pest of ripened fresh fruit in the orchard and dried fruit in postprocessing storage. It is a major problem with dried figs (Burks & Brandl, 2005;Galán et al, 2023;Smilanick, 1979) and dates (Bartelt et al, 1994a(Bartelt et al, , 1994bBurks et al, 2015;Emekci & Moore, 2015) in California. Carpophilus hemipterus, along with other species of the tribe Carpophlinae (Bartelt et al, 1994a(Bartelt et al, , 1994bPowell et al, 2020;Smilanick, 1979), often infest the maturing fruit.…”

“…The use of insecticides is the primary method to manage this pest in the field; however, adult beetles do not move into trees until the fruit begins to ripen, thus rendering the early preventative sprays ineffective. To enhance timing accuracy, the use of pheromone or food‐based traps for monitoring can be helpful (Bartelt et al, 1990; Bartelt, 1997; Emekci & Moore, 2015). However, despite these efforts, achieving effective control through insecticides remains complicated (Perry, 2021).…”

Dried fruit beetle, Carpophilus hemipterus (Linnaeus, 1758) (Coleoptera: Nitidulidae), is a serious pest of ripened fresh fruit in the orchard and dried fruit in postprocessing storage. Despite the economic impact and widespread distribution of C. hemipterus, there is a lack of functional genomics research seeking to elucidate features of molecular physiology for improved pest management. Here, we report the characterization of the gene named Vermilion in C. hemipterus (ChVer) that encodes for tryptophan 2,3‐dioxygenase. The Vermilion is frequently used as a visual marker for genomics approaches as tryptophan 2,3‐dioxygenase is involved in the biosynthesis of eye coloration pigments in insects. We identified 1628 bp long full‐length transcript of ChVer from transcriptomic database of C. hemipterus. The expression analysis among adult body parts revealed peak ChVer expression in head compared to thorax and abdomen, which is consistent with its role. Among the C. hemipterus developmental stages, peak ChVer expression was observed in first instar larva, second instar larva, and adult male stages, whereas the lowest levels of expression were seen in third instar larva, prepupa, and pupa. The nanoinjection of ChVer double‐stranded RNA in larval C. hemipterus resulted in a significant reduction in ChVer transcript levels as well as caused a loss of eye color, that is, the white‐eyed phenotype in adults. Characterization of visually traceable marker gene and robust RNA interference response seen in this study will enable genomics research is this important pest.

“…Like other fruits, dates are susceptible to attack by several pests, such as fungi, mites, and insects, either during growth and ripening in the field [3,4] or during postharvest operations and storage [5,6]. Among the insect pests that infest and damage dates, sap beetles (Coleoptera, Nitidulidae) are economically important since they can attack fruits both in the field and during storage [7]. The most common sap beetle that infests dates in almost all producing countries is Carpophilus hemipterus (Linnaeus, 1758), a species with worldwide distribution that can also feed on a variety of rotten fruits, and is considered a key pest of stone fruits in Australia [7].…”

The dried fruit beetle (Carpophilus hemipterus) is considered a key pest of dates, infesting fruits both in the field and during storage. Control measures against the species rely on the use of chemicals or heat treatments based on sunlight, hot air or radio frequency (RF) applications. Previous investigations that have aimed to define control procedures for a total disinfestation using RF treatments with different exposure durations have shown the typical behavior of adults in some trials, which, under the influence of temperature increases, started to escape from infested fruits. We focused on the application of different RF voltage-time combinations to induce the emigration of C. hemipterus adults from dates in order to produce a complete disinfestation. The results showed that the application of 2500 V RF for 8–10 min to infested dates resulted in nearly 100% of adults escaping from fruits, thereby cleaning the commodity with low or no mortality inside and outside the dates. These achievements provide a new strategy for controlling key insect pests of dates that could be applied at an industrial scale, allowing for the quick disinfestation of fruits without affecting the fruit with harmful substances, such as residues from chemical treatments, and without unwanted side effects on date quality.

Establishing the distribution of Carpophilus truncatus in Australia using an integrative approach for an emerging global pest

The nitidulid beetle Carpophilus truncatus is rapidly becoming a major pest of nut crops around the world. This insect first infested Australian almonds in 2013 and has since escalated to be the preeminent insect pest for the industry. Data pertaining to C. truncatus distribution are scant, but without awareness of its origin, distribution, and ecological factors that influence distribution, efforts to understand and manage the insect as a pest are stymied. Here, we employ an integrative approach to gain a multifaceted understanding of the distribution of C. truncatus in Australia. Methods employed were (1) reviewing historical records in insect collections to establish the presence of C. truncatus prior to commercial almond horticulture, (2) field trapping of insects to establish presence in regions of interest, (3) laboratory trials to determine the thermal limits of the organism, and (4) correlative species distribution modelling to describe its current distribution. We find that C. truncatus is more widespread across Australia than was previously known, with historical records preceding commercial almond production in Australia by a century. The methods developed in this study can be applied elsewhere in the world where C. truncatus is an emerging pest, or to novel pest species as they arise with increasing frequency in a globalised and warming world.
