Abstract:

First report of Hippodamia variegata (Goeze 1777) (Coleoptera: Coccinellidae) in Peru. The first record of Hippodamia variegata (Goeze 1777) (Coleoptera: Coccinellidae) in Peru is reported, which also constitutes the highest record of the species. This introduced species is already established in the rest of the continent, but its presence in Peru is confirmed in this contribution. A distribution map and a key to distinguish the two species of this genus present in Peru are presented.

Abstract:

Mating involves the transfer of sperm to females. Female reproductive investment is based on gamete numbers as well as gamete size. Females are more selective than males and this selection is based on numerous factors, like a male’s age, sexual status and familiarity. Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae) is an important natural enemy of many insect pests such as aphids, psyllids, whiteflies and mealybugs in many countries. We investigated female mate choice in Hippodamia variegate caging females with: (i) a young and a middle-aged male, (ii) a virgin and mated male and (iii

Abstract:

Intraguild predation among arthropod predators in agricultural ecosystems may have a negative impact on biological control. At present, there are few direct reports on trophic relationships among participants of predation in field groups. In this study, we measured the feeding choices of Hippodamia variegata (Goeze) towards mummies with different densities of Aphis gossypii Glover. The dynamics of the occurrence of mummies in the cotton field were investigated over 2017–2019. Singleplex PCR and multiplex PCR were used to detect the predation of 2090 H. variegata individuals on aphids and mummi

Abstract:

Natural enemies use odors to find prey in nature. The use of plant volatiles to attract natural enemy insects and promote their feeding on pests has great potential for practical application in integrated pest management. Of the 28 materials tested, ethyl benzoate, octyl formate, methyl jasmonate, and methyl dihydrojasmonate were significantly attractive to H. variegata. We tested the ladybeetle’s behavioral responses to three concentrations of the compounds (100, 10, and 1 µg/µL) and found that high and medium levels were both attractive to H. variegata.

An inventory of ladybirds was carried out in cereal fields in Zaghouan over three years to evaluate their seasonal apparition and their efficiency in decreasing aphid populations. Only two species, Coccinella algerica and Hippodamia variegata were identified. The delegation of Mograne was the most populated by ladybirds (64%). As the main result of the correlation analysis, the relationship between ladybirds and temperature was strong, especially during 2018 and 2019. The frequencies of morphs differed among years and seasons, and the number of individuals was more considerable with the aphids

Hippodamia variegata (Goeze), the variegated ladybug, is a predator of many insect pests, especially aphids. Sulfoxaflor is a chemical insecticide that can be used to control many sap-feeding insect pests, for instance, plant bugs and aphids, as an alternative to neonicotinoids in different crops. To improve the combination of the H. variegata and sulfoxaflor in an IPM (integrated pest management) program, we studied the ecological toxicity of the insecticide to the coccinellid predator at sublethal and lethal doses. We examined the influence of sulfoxaflor on larvae of H. variegata using expo

Melon aphids were reared on either Storm or Khasib cucumber cultivars to determine whether there would be a difference in their development and reproduction.

A survey of predatory and mycophagous Coccinellid beetles (Coleoptera: Coccinellidae) was conducted at four sites, representing four different ecosystems and altitudes ranging between 210 to 305 m within the Haridwar district, India, over a period of two years (July 2005 to June 2007). A total of 3502 adult Coccinellid specimens were collected and identified to 31 species, of which 19 species were recorded for the first time from within the Haridwar. These 19 newly recorded species belonged to 16 genera of four tribes and three subfamilies. The following 16 species belonged to the sub family C

Abstract:

Alfalfa is known to be an important reservoir harboring natural enemies. The reduction in insecticide sprayings in recent years has allowed us to study the coccinellid species complex in this crop and the relationship between these predators and aphids. Alfalfa was sampled by sweep-netting throughout its productive period in several commercial stands each year between 2010 and 2021. The numbers and species of aphids and coccinellids were recorded. Sixteen coccinellid species were found. Coccinella septempunctata and Hippodamia variegata were, by far, the most prevalent species, with the former

The adult preovipositional period and the total preovipositional period of female H. variegata were reduced as the prey density increased.

Four species viz., Leucinodes orbonalis (Guenee), Aphis gossypii (Glover), Henosepilachna vigintioctopunctata (Fabricius) and Macrosiphum euphorbiae (Thomas) were found to be major pests whereas Altica himensis (Shukla), Myzus persicae (Sulzer), Amrasca biguttula biguttula (Ishida) and Bemisia tabaci (Gennadius) were recorded as minor pests. The brinjal shoot and fruit borer emerged as the most prominent pest among all these. Among natural enemies four species viz., Coccin

Abstract Two important lady beetle species commonly found in alfalfa fields in Iran are the variegated lady beetle Hippodamia variegata Goeze and the seven spotted lady beetle Coccinella septempunctata (Linnaeus, 1758) (Coleoptera: Coccinellidae). These two species attack many aphid species including the pea aphid, Acyrthosiphon pisum (Harris) (Hemiptera: Aphididae). In this study, the seasonal population changes of A. pisum, H. variegata, C. septempunctata and the parasitoid, Dinocampus coccinellae (Schrank) (Hymenoptera: Braconidae) were studied in alfalfa fields in the 2012 and 2013 seasona

The aphid, Aphis gossypii Glover, is identified as a significant pest that causes severe damage to goji berries in China. To analyze the ladybird consumption of aphids, the functional responses of three ladybird species, Harmonia axyridis, Coccinella septempunctata, and Hippodamia variegata, and intraspecific competition among ladybird individuals were evaluated under laboratory conditions. Moreover, the practical impact of ladybirds on aphid population reduction was investigated in semi-field conditions. We found that all adult ladybirds of the three species exhibited a type II functional res

AbstractThe influence of natural enemies on the population growth of Diuraphis noxia (Mordvilko) in wheat fields in eastern South Africa was investigated. Since the natural enemies were not present in the initial stages, the apparent mortality observed must have been due to other causes. During the logarithmic phase of aphid population growth, predators, in particular the coccinellid Hippodamia variegata (Goeze), had a slight inhibitory effect on growth. During the decline phase of the aphid population, the potential population size was reduced by as much as 52% by predation. The most abundant
