“…On host plants other than citrus, several studies have analysed the dispersion pattern of WFT populations, which change with the host plant considered. As in our results, when comparing immature and adult stages on the same host plant, populations of immature thrips are always more clumped than populations of adults (Steiner, 1990; Salguero‐Navas et al., 1994; Wang & Shipp, 2001; Park et al., 2009). The b value of WFT in citrus flowers found in our study is considerably lower than the b value observed for the same thrips species in tomato and cucumber flowers by other authors.…”

Pezothrips kellyanus (Bagnall) (Thysanoptera: Thripidae) has recently emerged as an international pest of citrus. It causes severe scarring of the fruit surface and commercial downgrading of fresh fruit production. The goals of this paper were to determine the aggregation patterns of P. kellyanus on citrus, to establish an efficient sampling plan to assess their population density, and to develop an environmental economic injury level. The study was

“…The WFT abundance was more important compared to onion thrips (T. tabaci) and was predominant on all melon cultivars while T. tabaci was observed on Mimosa cultivar only. F. occidentalis was dominant on french bean in Kenya (Kasina et al, 2009), cucumber in Korea (Park et al, 2009), on cucumber and pepper crops at Bejaia (east coast of Algeria) (Oudjiane et al, 2018) and on tomato and pepper/ chili pepper at Biskra (Laamari & Houamel, 2015). Five thrips species were found in coastal and sub-coastal part of Algiers, including F. occidentalis, O. loti (Benmessaoud-Boukhalfa et al, 2010).…”

Globally, thrips pest of agro-ecosystems are well studied. Nevertheless, in Algeria this insect group remains poorly known. The research was conducted to determine thrips composition and population changes of F. occidentalis on three melon cultivar. The study highlighted six thrips species on three melon cultivars (Star plus, DRM and Mimosa), including two of economic importance pests, namely Frankliniella occidentalis and Thrips tabaci. The remaining species are: Odontothrips loti, Aeolothrips intermedius, T. minutissimus and Melanthrips fuscus. The western flowers thrips (WFT) F. occidentalis was eudominant species, while T. tabaci was subrecedent. Blue sticky traps allow detecting thrips early for monitoring and from crop development starting. A positive and significant relationship was observed between thrips abundance in traps and WFT recovered from flowers and leaves on all cultivars. The highest numbers of WFT were recorded on DRM flowers and Star plus leaves while the least numbers were noticed on Mimosa flowers and leaves. F. occidentalis flight activity was observed early in the growing season. Similar trend of thrips population changes was recorded during crop season. Nevertheless, one to two peaks of F. occidentalis population were registered on flowers and leaves on all cultivars. They were mainly observed in April when temperatures were high and humidity low, their numbers were not considerable. No fruits damage was observed in situ on all cultivars. This work allowed to improve knowledge about thrips linked to some melon cultivars the most used in greenhouse in the region of Biskra. The presence of these pests can be a source of concern for farmers. Extending monitoring to other crops and localities to know their status and distribution remains a priority due to direct damage caused and virus transmission hazard.

“…Some semaphoronts are simply ignored or discarded both at the time of collecting or sorting (Yeo et al., 2018), which leads to the very pertinent statement of Yeo and colleagues that, regarding insects, “the commonness‐of‐rarity problem is partially caused by not assessing diversity based on all life‐history stages” (Yeo et al., 2018:679). Estimates of the abundance of species, even in most applied contexts (e.g., pest control or biomonitoring), can be substantially different when distinct semaphoronts are considered (e.g., Buss & Salles, 2007; Park et al., 2009), which becomes even more problematic in cases where the responses of a given semaphoront are assumed to represent the species as a whole.…”

When faced with the daunting and exciting task of studying biodiversity, one must necessarily come to terms with a few challenging knowledge gaps, the so‐called biodiversity shortfalls. Given that biodiversity is inherently multidimensional, it seems rather natural to admit that hitherto unrecognized shortfalls, on other distinct aspects of biodiversity, should be considered. Here, we introduce the Haeckelian shortfall, which has as its nexus organismal ontogeny, and refers to the relative scarcity of knowledge about the distinct semaphoronts of a substantial fraction of all known species. The Haeckelian shortfall has a profound relevance on the matter of total evidence, in the context of systematics, besides several indirect effects on the other shortfalls, as they all are intimately interconnected. The importance of studying distinct semaphoronts is crystal clear: Besides the purest and most descriptive access to the ontogeny of species (the idiographic aspect), assessing those semaphoronts will certainly promote the advancement of relevant nomothetic knowledge, contributing to an increasingly meaningful eco–evo–devo. Overcoming the Haeckelian shortfall is certainly a major challenge in our task of knowing and preserving biodiversity.
