Productivity and resistance of okra (Abelmoschus spp.) to the cotton aphid Aphis gossypii glover (Hemiptera: Aphididae) under tropical conditions

Aphis gossypii Glover (Hemiptera: Aphididae) is among major arthropods causing significant damage to okra in the tropics. Resistant varieties could reduce aphid infestation and increase productivity. This study was carried out to identify aphid-resistant and high yielding okra accessions for management of the pest. Eleven farmers’ varieties and four aphid-resistant accessions from AVRDC were evaluated at its Nkolbisson station in Yaounde, Cameroon. Field screening was done to determine resistance to aphids, days to 50% anthesis and days to 50% commercial maturity. Aphid data was expressed as the area under infestation pressure curve and subjected to statistical analysis based on mean (m) and standard deviation (S.D.). Crop cycle and yield data were subjected to analysis of variance. Accession ‘VI033824’ was the most resistant to aphids (474 ± 41.9 per leaf) with yield 0.76 ± 0.26 t/ ha whereas the yield of the highly susceptible Babungo (1519.8 ± 0.0 aphids) was 1.33 ± 0.07 t/ha, 75.5% higher that the yield of the only resistant variety. Abelmoschus esculatus was less attacked (601.4 ± 60.0 aphids) by aphids than Abelmoschus caillei (826.0 ± 71.6 aphids; df = 1, 41; Pr {>Chi} = 0.037). The yield of A. caillei species were higher (1.26 ± 0.14 t/ha) than A. esculentus species (0.43 ± 0.08 t/ha; df = 1, 41; Pr {>Chi} = 0.0002). Hence, varieties with resistance, tolerance to aphids and earliness could be incorporated into integrated pest management of aphids and enhance productivity of okra

Black-bellied pangolin Phataginus tetradactyla documented in Deng Deng National Park, Cameroon, using camera traps

Information on pangolin life history and ecology is becoming increasingly available in African countries through community based surveys and camera-trapping. However, there is a paucity of information on the largely arboreal black-bellied pangolin Phataginus tetradactyla, which is categorized as Vulnerable on the IUCN Red List. By targeting fallen trees or logs with camera traps we recorded the black-bellied pangolin opportunistically in Deng Deng National Park (East Region, Cameroon), a locality within the presumed distribution of the species within Cameroon. We obtained a low trapping rate of 0.063 events per 100 trap days and the capture probability was one event recorded over 1571 trap-days (0.0006 captures per day). Deploying camera traps that focus on fallen trees or logs could be explored as a method for detecting black-bellied pangolins

Using local ecological knowledge to improve the effectiveness of detecting white-bellied pangolins (Phataginus tricuspis) using camera traps: A case study from Deng-Deng National Park, Cameroon

First paragraph: Pangolins (Order: Pholidota) remain one of the most challenging groups of mammals to detect and study. Yet, locating and documenting pangolin presence is essential to provide data on their distribution and population, which help to build effective conservation strategies. Pangolins are considered to be elusive and many of their ecological traits, such as low population density, largely nocturnal and solitary lifestyle, and use of burrows and cavities make it difficult to gather relevant information from commonly used monitoring approaches that are effective for other mammals (Ingram, Willcox, & Challender, 2019; Nash, Wong, & Turvey, 2016; Willcox et al., 2019). The white-bellied pangolin, Phataginus tricuspis, is a semi-arboreal species that feeds exclusively on ants and termites (Akpona, Djagoun, & Sinsin, 2008; Kingdon et al., 2013). They typically inhabit dense forest though also occur in forest–savannah–crop mosaics at times(Pietersen et al., 2019). The ecology of this species is poorly known due in part, to the challenges of studying pangolins and a lack of standardised research methods. (Willcox et al., 2019). Here, we evaluate the utility of local ecological knowledge (LEK) in tailoring camera-trap surveys, a detection method increasingly used for pangolins, to improve detection efficiency for occurrence and ecological studies for the white-bellied pangolin

Brachytrupes Serville 1838

Bioacoustics of <i>Brachytrupes</i> <p> The calling song of <i>Brachytrupes bapaensis</i> <b>sp. nov.</b> consisted of a loud continuous trill, which was heard and recorded several minutes without interruption (Fig. 6). The carrier frequency band of the song has its peak near 4.3 kHz, and the syllable period is about 8.6 ms corresponding to a SRR of 115 Hz. In both parameters the song is thus similar to that known from other <i>Brachytrupes</i> species (Table 3). The asiatic counterpart <i>Tarbinskiellus portentosus,</i> has also a similar song, but a lower SRR (Table 3). The stridulatory file of this species carries much more teeth (81–85) (Ahmad & Khan 2013) which are more densely packed (20 teeth/mm) (Ahmad & Khan 2013; but density 9.4 teeth/mm in the middle of the file [Godthi <i>et al.</i> 2022]) than in <i>B. bapanensis</i> <b>sp. nov.</b>. The calling song of <i>Brachytrupes tropicus</i> consisted of a loud, low-pitched continuous trill, which is emitted during several minutes without interruption. Pulse and interpulse durations are quite constant. The frequency band of the song ranged from 4.8 to 6.4 kHz with the peak near 5.7 kHz and a SRR of 118 Hz (Table 3, Desutter-Grandcolas 1998).</p>Published as part of <i>Simeu-Noutchom, Alain, Heller, Klaus-Gerhard, Nyobe, Philene Corinne Aude Um & Kekeunou, Sevilor, 2023, Taxonomy review of the genus Brachytrupes (Orthoptera: Gryllidae) with the description of a new species and key to the species, pp. 373-388 in Zootaxa 5336 (3)</i> on page 383, DOI: 10.11646/zootaxa.5336.3.4, <a href="http://zenodo.org/record/8281577">http://zenodo.org/record/8281577</a&gt
