The results indicate that optimum temperature for rearing H. dimidiata was 24 ±1 °C. The predatory ladybird beetle can be utilized as a part of integrated pest management program for the management aphid pests. Keywords: Harmonia dimidiata, Rhopalosiphum padi, temperature, biology, predatory potential Introduction Lady bird beetles are considered as the most important natural enemies of aphids and have been effectively utilized for the integrated control of several aphid pests. Ladybird beetles are [1] generalist predators that fed on a diverse range of insects . Aphids are the principal prey of ladybirds, whereas coccids, mites, honeydew, pollen, nectar and mildew are considered as secondary foods [2]. There are about 4400 predatory Coccinellid beetles in the world and their potential as bio control agents for different pests is quite promising. The sub-tropical ladybird beetle H. dimidiata (Fab.), commonly known as fifteen spotted lady bird occurs in China, Vietnam, India, Nepal, Pakistan and other countries of South-East Asia. In Pakistan it was [3] reported from Malakand, Swat, Murree, Peshawar, Islamabad and Rawlakot . Both larvae and adult ladybird beetle’ preys on different aphid species such as Myzus persicae, Schizaphis graminum, Aphis gossypii, Aphis fabae and Acyrthosiphon pisum [4]. H. dimidiate is highly voracious predator of aphids and has the ability to survive even at low [4] temperatures . These attributes make it a useful natural enemy for the purpose of biological control program against aphid pests of economically importance in sub-tropical regions of Pakistan. [14]. Among abiotic factors, temperature is the most important ecological aspect that strongly influences the rate of growth in insects and thereby affecting their seasonal population [5]. To evaluate the prospective of an insect as bio control agent, it is imperative to recognize its temperature necessities in relation to prey, such as low and high temperature thresholds as well as optimal temperature calculated for major life characteristics of insect. Increase in temperature usually increase the metabolic demand, as a result, predation and insect development rate tend to increase exponentially [6]. The effect of temperature is usually determined as a specific function of temperature and its effect on survival, fecundity, Correspondence demographic parameters, growth rate and development, which is then used for predicting [7] Javed Khan interaction among bio control agents and their host insects . Temperature driven models are PARC, Institute of advance often used to estimate the seasonal population dynamics of pests and natural enemies in field studies in agricultural science, situations [8].

Biodiversity Data Journal 4: e8030. doi: 10.3897/BDJ.4.e8030 Abstract Background Harmonia dunlopi (Crotch), a rare lady beetle species, was originally described from 'India' by Crotch (1874). But information on subsequent sightings of this species is absent and it has not been reported by anyone from India and its neighbouring countries ever since its original description. Because of this, Indian records of H. dunlopi were suspected to be probably misidentifications of H. dimidiata (F.), a species common in northern and northeastern India and also widely distributed in the Oriental region. New information A single male specimen of a species collected in recent surveys from Arunachal Pradesh, India, was suspected to be H. dunlopi. Comparison of this specimen with the collections at the Natural History Museum, London, confirmed that it belonged to Harmonia manillana (Mulsant), hitherto known from Malaysia, Indonesia and the Philippines. Harmonia manillana is a highly polymorphic species with many synonyms and based on examination of the type material, the following nomenclatural changes are proposed.

A substantial influence of prey density on the rate of larval growth and development was observed. Increased prey density reduced the developmental period. The study also revealed that larval development could be completed at the lowest prey density of 25 prey aphids. The analysis revealed a positive correlation between survival of developmental stages and density of prey provided. A relative increase in weight was observed with increasing density of aphid prey, but only up to a prey density of 100. The functional response exhibited by fourth instar larva exemplified type II predatory response with optimum response at a prey density of 100.

Forschler Received: 14 December 2016; Accepted: 20 March 2017; Published: 28 March 2017 Abstract: As part of my research on the mass production and augmentative release of ladybirds, I reviewed the primary research literature to test the prediction that ladybirds are effective aphid predators in greenhouses. Aphid population reduction exceeded 50% in most studies and ladybird release rates usually did not correlate with aphid reduction. The ratio of aphid reduction/release rate was slightly less for larvae than adults in some studies, suggesting that larvae were less effective (than adults) in suppressing aphids. Some adult releases were inside cages, thereby limiting adult dispersion from plants. Overall, the ratio of aphid reduction/release rate was greatest for ladybird adults of the normal strain (several species combined), but least for adults of a flightless Harmonia axyridis strain. The combined action of ladybirds and hymenopteran parasitoids could have a net positive effect on aphid population suppression and, consequently, on host (crop) plants. However, ladybird encounters with aphid-tending or foraging ants must be reduced. Deploying ladybirds to help manage aphids in greenhouses and similar protective structures is encouraged. Keywords: Aphididae; biological control; Coccinellidae; organic agriculture; pest management; predation 1. Introduction Culturing plants in greenhouses, glasshouses, or hothouses has existed in Europe and Asia since the early 19th century, with expansion into North America and other regions of the world in recent years [1–3].

Ovipositing females from invasive (Krasnodar Territory of Russia) and native (Far East of Russia) populations of Har- monia axyridis were fed one of a set of diets ranging from 50 Myzus persicae aphids every day to 1 aphid every 10 days and all were also provided with a 10% sugar solution. The experiment was conducted at 20°C under short (12 h) and long (18 h) day conditions. Most of the females from the native population that consumed 50 or 10 aphids per day continued to oviposit under both long and short day conditions. Females that consumed 1 aphid per day or every 2 days practically stopped laying eggs but under long day conditions their ovaries were still active, whereas under short day conditions ca 50% of them were reproductively inactive (only germaria present) and had a well-developed fat body. Further reduction in diet resulted in an increase in the propor- tion of reproductively inactive females.

Abstract Tenuisvalvae notata preys upon several mealybug species (Hemiptera: Pseudococcidae), a group of worldwide pests including Planococcus citri and Ferrisia dasyrilii. Although the consequences of variation in temperature for the development and reproduction of insects are generally appreciated, the consequences of potential interactions between temperature and prey for predatory insects are not. Thermal requirements and predation rates were determined for T. notata atdifferentconstanttemperatureswithbothpreyspecies.T. notata larvae developed to adults in experimental conditions > 18 to <38 °C. The upper thermal limit for egg hatch was 34 °C and for pupation was 33 °C. Adults reared at ≥32 °C did not lay eggs and survived less than 1 week. Prey species did not affect lower temperature thresholds or thermal constants for development from egg to adult. Furthermore, prey did not affect a number of reproductive traits, but the interaction between temperature and prey affected changes in developmental times and oviposition rate with age. Predation rate of T. notata increased as a function of temperature, and T. notata adults generally consumed more nymphs of P. citri than F. dasyrilii.Thesefindings indicate that T. notata is well adapted to the tropical and sub-tropical temperatures and may prove useful for the biological control of some native and non-native mealybugs.
