“…The beetles were identified as Conotelus luteicornis Erichson (Coleoptera: Nitidulidae) (Figure 1) based on the comparison with the holotype specimens. The adult measures approximately 4.0 mm in length with an elongated dark-colored body (Potin et al, 2016).

“…Young flowers and fruits can be aborted in high infestations of these nitidulids in the culture and the fruits that do not fall are blackened and deformed. Besides, injuries caused by these insects fed on passion flowers can serve as a gateway for opportunistic pathogens (Potin et al, 2016).…”

Record of Conotelus luteicornis Erichson (Coleoptera: Nitidulidae) in passion fruit vine in Acre state, Brazil

2021

The first record of Conotelus luteicornis Erichson (Coleoptera: Nitidulidae) was made in a commercial passion fruit vine planting in the municipality of Senador Guiomard, Acre state, Brazil. The insects were found inside the flowers where larvae and adults feed, causing early abortion and, consequently, losses in production. Therefore, the first record of this species is made in the Brazilian Amazon. Researches related to damage level, population dynamics, prospecting for natural enemies, and control methods are strongly recommended since this nitidulid is an insect with high harmful potential to the passion fruit vine culture in the Amazon region.

“…One species identified as Conotelus mexicanus has been introduced to Hawaii in the 20th century, where it occurs primarily in morning glory flowers (Convolvulaceae) but also in other flowers, including those of passionfruit (Nishida, ). There were no reports of any significant damage caused by Conotelus species until Potin, Andrade, Pereira, and Kassab () reported infestations of cultivated passionfruit flowers in the Rondônia region of the Amazon biome, which resulted in economic losses. In that ecosystem, adult beetles damage many parts of the flowers, and the larvae can injure the developing fruits.…”

Species of the nitidulid beetle Conotelus found in flowers of Convolvulaceae and other plants across the New World and in Hawaii consistently harbour a yeast community dominated by one or more large‐spored Metschnikowia species. We investigated the yeasts found in beetles and flowers of cultivated passionfruit in Rondônia state, in the Amazon biome of Brazil, where a Conotelus species damages the flowers and hinders fruit production. A sample of 46 beetles and 49 flowers yielded 86 and 83 yeast isolates, respectively. Whereas the flower community was dominated by Kodamaea ohmeri and Kurtzmaniella quercitrusa, the major yeasts recovered from beetles were Wickerhamiella occidentalis, which is commonly isolated from this community, and a novel species of large‐spored Metschnikowia in the arizonensis subclade, which we describe here as Metschnikowia amazonensis sp. nov. Phylogenetic analyses based on barcode sequences (ITS‐D1/D2) and a multigene alignment of 11,917 positions (genes ura2, msh6, and pmt2) agreed to place the new species as a sister to Metschnikowia arizonensis, a rare species known only from one locality in Arizona. The two form sterile asci when mated, which is typical of related members of the clade. The α pheromone of the new species is unique but typical of the subclade. The type of M. amazonensis sp. nov. is UFMG‐CM‐Y6309T (ex‐type CBS 16156T, mating type a), and the designated allotype (mating type α) is UFMG‐CM‐Y6307A (CBS 16155A). MycoBank MB 833560.

Conotelus sp. (Coleoptera: Nitidulidae) is a substantial pest of passion fruit production in the Zona da Mata region of Rondônia, Brazil, making this agricultural activity unviable. This study evaluated the toxicity of registered and unregistered chemical insecticides for passion fruit cultivation against Conotelus sp. under laboratory conditions. Eight insecticides were evaluated at recommended field application concentrations. Passion fruit flowers sepals were immersed in insecticide solutions, and five larvae measuring 2 to 3 mm were placed on these sepals. Additionally, LC50 and LC90 values were determined for the insecticides fenpropathrin and chlorpyrifos. The results showed that chlorpyrifos, fenpropathrin, spinetoram, imidacloprid, chlorfenapyr, and thiamethoxam were effective in controlling Conotelus sp. larvae, demonstrating their potential for managing this insect pest. The LC50 values of chlorpyrifos and fenpropathrin for Conotelus sp. were 3.19 g a.i./100 L and 22.09 g a.i./100 L, respectively, showing the higher toxicity of chlorpyrifos. The estimated LC90 values for chlorpyrifos and fenpropathrin are 8.36 g a.i./100 L and 79.04 g a.i./100 L, respectively. These findings strengthen the scientific basis for selection and implementation of management measures to control Conotelus sp. in passion fruit plantations.
