“…In addition, wild cottons vary in seasonal timing of ßower and fruit production (Ulloa et al 2006), and boll weevils may be adapted to different phenologies of particular Sonoran hosts, attacking plants at different times. Such differences have been reported for TW on wild cotton versus boll weevils adapted to cultivated Þelds in Arizona, accounting for the purported lack of economic importance for the former (Fye 1968, Bottrell 1983.…”

Although the boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), is a devastating pest in the United States and Mexico, its population structure and genetic diversity in Mexico on wild and cultivated cotton hosts (genus Gossypium) is poorly understood. Past studies using morphology, host use, and distribution records suggest that A.grandis grandis comprises three forms with host-associated characteristics: the southeastern form (from domesticated Gossypium hirsutum L., southeastern United States and northeastern Mexico), the thurberia form (from Gossypium thurberi Todaro, Arizona and northwestern Mexico), and the Mexican form (from multiple Gossypium species and other malvaceous plant genera in the remainder of Mexico and Central America). However, the phylogenetic relationships, host preferences, and distributions of these forms are not completely understood. An alternative hypothesis of an eastern and western form of the boll weevil is suggested by the suspected phylogeographic range expansion from an ancestral distribution in the tropics northward along both Mexican coasts, culminating in the maximally contrasting phenotypes observed in the northeastern and northwestern arms of the current distribution. In this study, we sequenced one mitochondrial and four nuclear genes to gain insight into the evolutionary relationships among the putative forms and their distributions on wild and domesticated cotton hosts. Using models of evolution, we compared the three-form to the two-form classification and to two alternative classifications that incorporate geography and host use traits. The genetic data at most loci provide stronger support for the two-form than the three-form hypothesis, with an eastern and western group separated by the Sierra Madre Occidental mountain range. They do not support separate taxonomic status for boll weevils developing onG. thurberi.

“…1976, Curry ei al. 1982. Bottrell 1983 tem demonstrado que, quando no ecossistema da cultura do algodoeiro a umidade relativa é igual ou menor que 50% e a temperatura do solo for maior que 38°C, em tempo reduzido os bicudos imaturos morrem no interior dos botões florais.…”

“…Logo em seguida, o botão floral cai ao solo ou fica dependurado por um fio que liga seupedúnculo àplanta. Seaprimeira hipótese ocorre, fica expostoa alterações do microambiente que variam desde completa sombra até inteira exposição à luz solar (Bottrell 1983), o que vai determinar sua menor ou maior perda de umidade e, consequentemente, a chance de sobrevivência da forma imatura que se encontra em seu interior. Fica, então, claro que a sobrevivência do inseto é influenciada pelo botão floral em si e pela sua exposição à insolação, temperatura e umidade (De Michele ei al.…”

Relation Between Soil Surface Temperature and Boil Weevil Anthonornusgrandis Boh.(Coleoptera: Curculiomdae) EmergenceA possible interference of soil surface temperature ou boil weevil Anlhonomus grandis Boh. development was investigated. Cotton fields were planted with cv. IAC-20, with rows spaced 0.80m, and five plants/linear meter, were established in Campinas Experimental Station, São Paulo State, Brazil from November 1991 to Januaiy 1994. The soil surface temperatures were registeredwith a soil termogrnph, and the evaluation of temperature effect was conducted with teniperatures higlier than 38°C. Boli weevil emergence was 71.3, 53.8 and 3 5.9% for 9 1/92; 92/93 and 93/94 seasons, respectiviely, when the infested squares remained underconditions of soil surface temperature higherthan 38°C. However, itwas observed 355 and 46.1% of no emergence for 91/92 and 93/94 seasons, respectively when soil surface temperature remained below 38°C. Intact anthers, larvae, pupae and adults death, and parasitized larvae were found inside squares in both conditions of soil surface temperatures (above and below 38°C). These results indicated that soil surface temperature had no interference with boil weevil development.

“…In such schemes a variety of control techniques and information are systematically combined to exert an overall check on a given pest, but not on the whole pest complexes in the biocenosis of the crop in question (Soerjani and Morallo-Rejesus, 1980). But, because the programme had dealt mainly with the problem of the boll weevil, Anthonomus grandis, other pest problems in the cotton biocenosis would in the long run be created or intensified as discussed by some authors (Bottrell, 1983;Matthews, 1983).

Despite the growing acceptance and adoption of the IPM concept, up until now no "optimal" or pragmatic IPM programme has been realized. This is apparently because most of these programmes are still in need of new types of pesticides, with no or negligible adverse impact on the environment including the non-target beneficial arthropods. From a practical perspective, such pesticides are still rather far reaching. Most, if not all, pesticides in current use as components of IPM programmes are so far belonging, in one way or another, to the conventional pesticides. It is admitted that in designing IPM programmes, several efforts should be made to minimize not only the frequency of pesticide applications but also their negative consequences on beneficial arthropods. Whilst the first goal has been achieved in several situations, the other one appeared hardly accessible. A number of methodologies are currently being suggested to cause conventional pesticides more selective, but apart from having many technical and other constraints, they might at best have fallen short of providing the hopeful solution. These together with other problems facing the development and practical utilization of juvenoids and related compounds are discussed mainly in view of their possible contribution to tropical pest management.Resume-Bien que le concept MIP ait ete reconnu et que son application pratique soit de plus en plus frequente, aucun programme pragmatique satisfaisant n'a ete realise jusqu'a present.Peut-etre est-ce parce que la plupart de ces programmes demandent l'introduction de nouveaux types de pesticides exercant peu ou pas d'action nocive sur l'envirronement y compris sur les arthropodes. Malheureusement, il est impossible que de tels pesticides soient fabriques a plus ou moins breve echeance. En ce qui concerne la plupart des pesticides d'usage courant, comme ceux des programmes MIP, on doit s'appliquer a en diminuer non seulement la frequence d'utilisation mais aussi l'action nocive sur les arthropodes.Mais s'il est relativement facile d'atteindre le premier objectif, on se heurte a des problemes insolubles quant au second. Par consequent, on se contente generalement de proposer des methodes permettant de rendre les pesticides conventionnels plus selectifs, car les differentes contraintes, techniques et autres, constituent des obstacles insurmontables a la realisation des solutions souhaitees. Tous ces problemes ainsi que ceux auxquels on se heurte dans l'utilisation de plus en plus frequente des juvenoides et produits similaires, sont au coeur des discussions, puisque leur solution rendra possible une lutte efficace contre les insectes nuisibles des regions tropicales.
