“…The negative effect of accumulated precipitation on the population abundance of winged aphids corroborates the results obtained previously (Rebonatto et al, 2015;Chamuene et al, 2018;Soares et al, 2020). Precipitation affects the population of aphids, increasing mortality, both by drowning and by the increase in air relative humidity, providing favorable environment for entomopathogenic fungi (Soares et al, 2020). Although the current study investigated the population dynamics of aphids and related parasitoids, the availability and quality of host plants are yet to be studied.…”

“…The increase in air temperature caused an increase in the development rate, resulting in massive growth and greater development of winged morphotypes (Auad et al ., 2009).

In different parts of the world, aphid populations and their natural enemies are influenced by landscapes and climate. In the Neotropical region, few long-term studies have been conducted, maintaining a gap for comprehension of the effect of meteorological variables on aphid population patterns and their parasitoids in field conditions. This study describes the general patterns of oscillation in cereal winged aphids and their parasitoids, selecting meteorological variables and evaluating their effects on these insects. Aphids exhibit two annual peaks, one in summer–fall transition and the other in winter-spring transition. For parasitoids, the highest annual peak takes place during winter and a second peak occurs in winter–spring transition. Temperature was the principal meteorological regulator of population fluctuation in winged aphids and parasitoids during the year. The favorable temperature range is not the same for aphids and parasitoids. For aphids, temperature increase resulted in population growth, with maximum positive effect at 25°C. Temperature also positively influenced parasitoid populations, but the growth was asymptotic around 20°C. Although rainfall showed no regulatory function on aphid seasonality, it influenced the final number of insects over the year. The response of aphids and parasitoids to temperature has implications for trophic compatibility and regulation of their populations. Such functions should be taken into account in predictive models.

“…These factors can cause direct or indirect changes to aphids' fertility, mortality and migration rates (Fidelis et al, 2019 ). In addition, abiotic factors such as rainfall, temperature, and relative humidity, and biotic factors such as the incidence of natural enemies and host plants, all affect the rates at which aphid populations increase and the eventual density of aphids on their hosts (Bale et al, 2002 ; Nietschke, Magarey, Borchert, Calvin, & Jones, 2007 ; Soares et al, 2020 ).…”

The aphids Lipaphis erysimi pseudobrassicae (Davis) and Myzus persicae (Sulzer) pose serious threats to the production of cruciferous crops in the tropics. Understanding their population dynamics is important for developing integrated pest management programmes to minimize their damage to crops. This study investigated the effects of climatic factors, natural enemies and plant age on the population dynamics of these pests. The population density of aphids and their natural enemies in 20 cabbage plants, and weather conditions were monitored for five cropping seasons from 2019 to 2021 in two agroecological zones of Ghana (Coastal Savannah and Deciduous Forest zones). The highest population density of L. e pseudobrassicae was recorded in January (dry season) in both agroecological zones, while the highest population density for M. persicae occurred in September (minor rainy season) and August (dry spell) in the Coastal Savannah and Deciduous Forest zones, respectively. The highest aphid densities were noted to occur during periods with low relative humidity and low rainfall. The population density of L. e. pseudobrassicae was significantly negatively related to plant age, air temperature and relative humidity, and positively related to syrphids (Paragus borbonicus) and spiders in the Coastal Savannah zone, while in the Deciduous Forest zone, it was significantly positively related to coccinellids. On the other hand, M. persicae population density was significantly positively related to syrphids and coccinellids in the Deciduous Forest zone. Rainfall negatively affected syrphids in the Coastal Savannah zone, while air temperature positively affected syrphids and negatively affected spiders in the Deciduous Forest zone. Coccinellids had a significant positive relationship with relative humidity in the Deciduous Forest zone. This study provides important insights into the key factors that regulate aphid population densities on cabbage and will support development of timely interventions to manage these pests.

“…While changes to its taxonomy and inferred evolutionary relationships have been recently accomplished (Metz & Thompson 2001;Thompson & Thompson 2006;Mengual et al 2008Mengual et al , 2012Borges & Couri 2009;Mengual 2011;Thompson 2016), the life history and larval biology of few species have been documented. In common with most tropical Syrphinae species, the larval stages of most Toxomerus species are unstudied, but the species with described larval life histories are either pollen-feeders (Reemer & Rotheray 2009;Nunes-Silva et al 2010;Jordaens et al 2015;Dumbardon-Martial 2016) or predaceous on a wide-range of soft-bodied arthropods including aphids, caterpillars, beetle larvae, planthoppers, gall midges, thrips, mealybugs, whiteflies, mites, or insect eggs (Sampson et al 2002;Rojo et al 2003;Hopper et al 2011;Fok et al 2014;Sturza et al 2014;Torres et al 2014;Campos et al 2017;Jirón-Pablo et al 2018;Soares et al 2020).…”

Attracted to feed, not to be fed upon – on the biology of Toxomerus basalis (Walker, 1836), the kleptoparasitic ‘sundew flower fly’ (Diptera: Syrphidae)

The complete life history of the kleptoparasitic ‘sundew flower fly’, Toxomerus basalis, is presented and illustrated. Adults of this species are photographed alive for the first time, including video recordings of larval and adult behaviour. Adult flies of both sexes visit Drosera (sundews) and show territorial behaviour around the plants, avoiding the dangerous sticky traps and demonstrating recognition of their larval host plant. Females lay eggs directly on non-sticky parts of the Drosera host plants, such as on the lower surface of the leaves and flower stalks, but apparently also on other plants growing in close proximity with the sundews.
